Weed Technology, 10(4):835-841; 22 ref. In this article, we report a de novo assembly of a landrace (A.hyp_K_white) and demonstrate that, in the presence of a reference genome for a distal variety, a chromosome-level assembly can be generated at a reasonable cost. U.S.A. 110, 1785–1790. Figure 4 validates taxonomy-based classification (color-coded accessions) of the majority of the accessions and landraces. The bam files of each sample can be visualized in the respective genome browser (link to the same is available in the data availability section) Also, the expression profiles of all the 12 predicted genes from the lysine pathway across developmental stages is provided in Figure 5A along with the corresponding exon number and sizes compared to Arabidopsis Figure 5B. It is among the species consumed as Quelite quintonilli in Mexican food markets. Sci. A. hybridus with accession of PI605351 clusters in the same clade as Suvarna with another accessions (PI477913) from A. cruentus. Phytochemical Studies of Rajigara Amaranthus Species for its Potential use in Medicine. Amaranthus hecticus Willd. Bioinformatics 26, 841–842. Whole-genome sequencing from a few landraces and ornamental varieties generated in-house and several other accessions from public sources are clustered using 20,548 SNPs out of the 27,658 SNPs reported for grain amaranths (Figure 3A). doi: 10.1186/gb-2009-10-8-r88. Since this landrace is more closely similar to all other landraces and accessions for A. hypochondriacus from India and South Asia (Supplementary Table S1), AhKP offers a better reference for the improvement of grain amaranth crops in South Asia. The clusters were generated in cBot and paired-end sequenced on Illumina HiSeq 2500 platform. Figure 3. The mapped files were processed using samtools (Li et al., 2009) and raw read count was counted for all predicted genes using bedtools multiBamCov (Quinlan and Hall, 2010). A. 81, 559–575. Avaliable at: https://hort.purdue.edu/newcrop/proceedings1999/v4-184.html (accessed October 4, 2020). Whole Genome libraries for A.hyp_K_white, A.hyp_K_red, A.cru_ornamental, A.cau_ornamental and A.cru_Suvarna were prepared using the TruSeq DNA Sample Preparation Kit (Illumina) by following the manufacturer’s low throughput protocol. We generated WGS data with coverage of ∼50–150X using the Illumina platform for selected landraces and ornamental varieties. The quality, quantity, and size distribution of the libraries were evaluated using Qubit (Invitrogen) and TapeStation (Agilent) (Sunil et al., 2014). Annotation of AhKP was done using multiple approaches (i) Augustus (Hoff and Stanke, 2019) (v3.2.3) prediction using Arabidopsis as model and (ii) MAKER (Campbell et al., 2014) genome annotation pipeline with (with and without Augustus) default parameters, was used for AhKP annotation. This platform is a single-molecule, real-time (SMRT) sequencing machine that uses a sequencing-by-synthesis method to generate good quality very long reads. J. Janick (Alexandria, VA: ASHS Press), 184–189. 13(2): 259. 15:74. doi: 10.1186/s12915-017-0412-4, Love, M. I., Huber, W., and Anders, S. (2014). Correction: chromosomal-level assembly of the asian seabass genome using long sequence reads and multi-layered scaffolding. BMC Biol. As a second approach, the phylogenetic tree shown in Figure 4A and generated using AhKP as reference (Figure 4A) combines variants called for the 94 accessions using both raw genotyping-by-sequencing (GBS) data from public sources (Wu and Blair, 2017) and whole-genome sequencing (WGS) data for listed accessions in Supplementary Table S2. More recently, a high-quality chromosome-level assembly of A. hypochondriacus (PI558499, Plainsman) was reported. Natl. Purcell, S., Neale, B., Todd-Brown, K., Thomas, L., Ferreira, M. A. R., Bender, D., et al. incurvatus Amaranthus hybridus Linnaeus, subsp. Although the family (Amaranthaceae) is distinctive, the genus has few distinguishing characters among the 75 species present across six continents. doi: 10.1073/pnas.1220349110, Kolmogorov, M., Yuan, J., Lin, Y., and Pevzner, P. A. The merged SNP file was processed using PLINK (Purcell et al., 2007) and ADMIXTURE (v1.3) was used to analyze the population structure (Alexander and Lange, 2011). Amaranthus hybridus grows from a short taproot and can be up to 2.5 m in height. (synonym) Amaranthus hybridus var. bioRxiv [Preprint].

Br. Here, a chromosome level assembly (AhKP) of a landrace, A.hyp_K_white, under contiguous cultivation in India for over several centuries is reported. Bioinformatics 25, 2078–2079. Genomic DNA was extracted from fresh leaves using the DNeasy Mini Plant DNA Extraction kit (Qiagen) following the manufacturer’s protocol and quantified using fluorometry (Qubit 2.0, Invitrogen). Similarly, the malarial strain, Plasmodium falciparum HB3, was improved using the reference of P. falciparum 3D7 combined with an assisted assembly approach that significantly improved the contiguity of the former (Gnerre et al., 2009). Lh3/Wgsim. No use, distribution or reproduction is permitted which does not comply with these terms. (B) block plot, (C) circular and (D) dot plot showing synteny of chromosomes of AhKP assembly on to Plainsman (A.hyp.V2.1). Toward this end, our lab had initiated sequencing the genome of Amaranthus (A.) Only 97 out of 107 samples from both GBS and WGS data were filtered based on their good clustering and bigger sample size. Am. hybridus S. Watson Amaranthus eugenii Sennen Amaranthus flavescens Moq. We selected this landrace because it is well adapted for cultivation in India during the last century and is currently a candidate for TILLING-based crop improvement. Amaranthus hybridus can be consumed in various ways, namely made vegetables, directly consumed when raw, or made into … Possible aliases, alternative names and misspellings for Amaranthus hybridus. While a large number of landraces, adapted to local environments for small scale cultivation exist, their origins and relations to the large germplasm, collection at GRIN-Global are not established. (2017) from 16 developmental stages including leave, stem and root from 15,20,25 and 30 day plant, bud, flower, young seed and mature seed were mapped to AhKP reference using bowtie2 (Langmead and Salzberg, 2012). This suggests that A. caudatus is a major clade under A. quitensis. Amaranthus hybridus L. is a competitive weed for summer crops in South America.In this article, we intend to unravel the molecular mechanisms by which an A. hybridus population from Argentina has become … (2017). Briefly, for PE libraries, the fragmented DNA was end-repaired, 3′-adenylated, ligated with Illumina adapters, and PCR enriched with Illumina sequencing indexes. VASCAN was last updated on 2020-09-04; Comment nous citer. Anuales, tallos erectos, glabros abajo, tornándose subglabros o escasamente pubescentes hacia arriba con tricomas de hasta 1 mm de largo, muy delgados e irregularmente doblados; monoicas. Also, the tree generated prior to the normalization method has been presented in Supplementary Figure S3 for highlighting the extent of improvement upon normalization. Stems angled or with longitudinal lines or ridges, green or brown, leaves alternate, broadly lance late to ovate, discolors, conspicuously veined beneath, up to 7 cm long, 4 cm wide. We have devised a method to normalize for the same during the variant calling (see section “Materials and Methods”). At K = 6 other unique components within A. hypochondriacus gets resolved. Meera, N., Lohithaswa, H. C., Murthy, N., and Hittalmani, S. (2014). thus retroflexus, Amaranthus graecizans, Amaranthus dubius, and Amaranthus hybridus. Workflow used in integrating WGS data with GBS. Also, the two landraces under A. hypochondriacus, A.hyp_K_white and A.hyp_K_red, cluster apart within the same clade validating our observation that the seeds of these two varieties faithfully produce plants with inflorescence unique to the respective phenotype. incurvatus (Grenier & Godron) Brenan, Watsonia 4: 268. 77, R93–R104. 990. Figure 6. All the accessions from A. quitensis and A. caudatus clusters together in a single clade with two branches of A. quitensis enclosing A. caudatus, which is also reported using only GBS data using A.hyp.V.2.1 as reference (Lightfoot et al., 2017).

A high-performance computing toolset for relatedness and principal component analysis of SNP data. 3 Vegetable Ama-ranthus can be easily distinguished by inflorescence features like mostly or exclusively axillary glomerules or short spikes (Fig. It is interesting to note that A.cau_ornamental clusters close to A.cau_Bolivia_PI642741. Grain amaranth, also known as Ramdana (The God’s grain) or Rajgira or Rajeera, has been in continuous cultivation at least since last century in India. 10:R42. The plant was used for food and medicine by several Native American groups and in traditional African medicine. More recently, our group demonstrated that two draft genomes of the same species could be used to mutually improve scaffolding of the genome of Anopheles stephensi to the point that a set of low-resolution physical markers was sufficient to build the chromosomes (Chida et al., 2020). doi: 10.1016/S0022-2836(05)80360-2, Batzoglou, S. (2005). Amaranthus chlorostachys var. Giving chromosomal context to genes and other genetic elements is one of the most sought-after goals in genome assembly. Amaranthus powellii: bracteoles mostly 4.5--6 mm long, mostly 2--3 times as long as the sepals (vs. A. hybridus, with bracteoles mostly 2.5--4 mm long, 1.2--2 times as long as … Suvarna (R 104-1 -1), a pureline released by University of Agricultural Sciences (UAS), Bangalore-1992 from the material “Rodale Plus” received from Rodale Institute (Rathod, 2017) has previously been classified as A. hypochondriacus in Meera et al., 2014. In the context of increasing demand on water and other natural resources from an increasing world population, grain amaranths offer an alternative to other staple cereals such as rice or wheat. ADMIXTURE analysis shown in Figure 4B suggests that there is significant gene flow between A. caudatus and A. quitensis. This landrace was selected for its aggressive growth, and its yield compared to a few other landraces including one with red inflorescence cultivated in India. Reference-assisted chromosome assembly.

Curr. While GBS is a cost-effective technology for classifying large number of accessions, it covers only 10% of the genome, which depends on the sample preparation protocol and reagents used. The reads were demultiplexed using GBSX (Herten et al., 2015) using the provided barcode sequences. Protoc. A classification based on hundreds of thousands of SNPs validated taxonomy-based classification for a majority of the accessions providing the opportunity for reclassification of a few. This Whole Genome Shotgun project has been deposited at DDBJ/ENA/GenBank under the accession JPXE00000000. bellardii Moq. Amaranthus hybridus L. (Amaranthaceae) commonly known as ‘Cheera’ in Malayalam, is an erect branched annual herb distributed throughout tropical and temperate regions of India as a common weed in the agricultural fields and wastelands. The two predicted libraries of repeat elements were merged together and repeat masking was done using RepeatMasker version 4.1.0 (Smit and Hubley, 2008–2015). Amaranthus hybridus var. The tree generated using the 20,548 SNPs (Figure 3B) is independent of any reference and hence, can be considered unbiased.

Leaves glabrous or with sparse hairs on the main veins below… Effect of plant density and planting geometry on growth and yield of grain amaranths. In this report, Suvarna is undoubtedly classified as A. cruentus based on 20,548 reported SNPs and roughly 6 million variants covered in WGS data (Figure 3). Guillen-Portal, F. R., Baltensperger, D. D., Nelson, L. A., and D’Croz-Mason, N. (1999). Interestingly, similar to Figure 2, A.hyp_K_white and A.hyp_K_red, both landraces from India cluster closely together along with accessions A.hyp_Nepal_PI619259 and A.hyp_India_PI481125. J. Genes involved in lysine biosynthesis pathway were identified by BLASTP (Altschul et al., 1990) analysis using Arabidopsis proteins. More recently, using genotyping-by-sequencing (GBS), 94 accessions for grain amaranths have been classified (Wu and Blair, 2017). From the mapped reads, variants were called using samtools (v1.9) mpileup (Li et al., 2009) and bcftools (v1.9) (Li et al., 2009). 2017 (Wu and Blair, 2017) WGS (Lightfoot et al., 2017)2. U.S.A. 108, 10249–10254. Canu: scalable and accurate long-read assembly via adaptive k-mer weighting and repeat separation. Amaranthus hybridus is a herbal plant that is grown to be consumed leaves. PacBio reads using RSII technologies sequenced in 2013 with an average length of 7.5 kb with a coverage of 25X for A.hyp_K_white were assembled using state-of-the-art tools CANU (Koren et al., 2017)and FLYE (Kolmogorov et al., 2019) to obtain an assembly with L50 values of 1395 and 944, respectively, as shown in the flowchart in section “Materials and Methods” (Figure 6). Amaranthus hybridus was originally a pioneer plant in eastern North America. JBrowse: a next-generation genome browser. It is also found in many provinces of Canada, and in parts of Mexico, the West Indies, Central America, and South America. boiRxiv [Preprint]. Nucleic Acids Res. The Amaranth database is running on EC2 instances of Amazon cloud service (AWS). The sequence alignment/map format and SAMtools. BMC Bioinformatics 16:73. doi: 10.1186/s12859-015-0514-3, Hoff, K. J., and Stanke, M. (2019). In this context, the draft assembly of a landrace from India was sequenced and reported (Sunil et al., 2014). Sci. Here, to understand/translate the high-lysine phenotype and to validate the gene structure obtained from our annotation efforts, the transcriptomes have been mapped to AhKP reference and the expression profiles of the predicted genes have been generated across the developmental stages. Li, H. (2020). The size selection for all the libraries were done using solid-phase reversible immobilization (SPRI) beads (Agencourt AMPure XP Beads) from Beckman Coulter. 39:e68. Amaranthus hybridus is an erect annual plant with a stem that can be much-branched to nearly free of branches; it usually grows 30 - 200cm tall, occasionally to 250cm 270 Title Acad. Before long-read sequencing became commonplace, experimentally generated mate-pair reads of increasing insert sizes were routinely used to generate scaffolds from contigs. A whole-genome assembly of the domestic cow. This section is divided into three parts. Smooth Pigweed (Amaranthus hybridus (syn: quitensis)) is a dicot weed in the Amaranthaceae family. In the age of genomics-based crop improvement, a high-quality genome of a local landrace adapted to the local environmental conditions is critically important. In fact, using independent mapping data and conserved synteny between the cattle and human genomes, 91% of the cattle genome was placed onto 30 chromosomes (Zimin et al., 2009). The taxonomy-based classification seems reproducible with green being A. hypochondriacus, light blue being A. cruentus, dark blue being A. caudatus and yellow being Amaranthus quitensis. J. DNA Res. Whole-genome PacBio sequencing was done by Molecular Biology and Genomic Core, Washington University using P5/C3 chemistry on the Pacific Biosciences RSII platform. Amaranthus hybridus var. (2004).

The circular DNA was sheared again as explained earlier, and the biotinylated fragments were purified using streptavidin beads (DynabeadsTM M-280 Streptavidin, Invitrogen), the fragments were end-repaired, 3′-adenylated and ligated with Illumina adapters. A decade-long research conducted by the Rodale Institute during the 1980s enabled the creation of more than 800 species/varieties, which are currently maintained in a germplasm (GRIN-Global). paniculatus Dostal, Kvetevna CSSR 444. Amaranthus hybridus Taxonomy ID: 3565 (for references in articles please use NCBI:txid3565) current name. It grows in many different places, including disturbed habitats. This was further improved by merging the Illumina assembly from the draft genome reported elsewhere and polished using the Illumina reads. These two assemblies were then merged using Quickmerge (Chakraborty et al., 2016) to improve the L50 to 623. One way to do this would be to identify and use the alleles found from GBS data with the respective alleles found from WGS. doi: 10.1101/gr.215087.116, Korf, I. Proc. More recently, the plummeting cost of sequencing has democratized the application of genomics technologies not only to non-model crops but has extended its reach to individual landraces with direct benefit to local farmers. Users can access the Jbrowse by clicking on the Genome browser button or using the tools menu. Farm Sci. Front Plant Sci. At this stage, the scaffolds were long enough to allow the use of HiC data generated for Plainsman to obtain high-resolution assembly (AhK20). Such an approach can simply be extended for reference-guided improvement of draft genomes of a plant using simulated mate pairs of varying insert sizes from an existing assembly of a different variety/cultivar of the same species. The seed could be … The assembly statistics of the initial assembly was sufficient for reference-based scaffolding using both the simulated mate-pairs from the reference genome and raw HiC data for Plainsman from public resources (Lightfoot et al., 2017). Repeat elements for the Plainsman and the A.hyp_K_white variety of A. hypochondriacus assemblies were predicted using RepeatModeler version 2.0.1 (Flynn et al., 2019) along with LTR discovery. Beck Homonyms Amaranthus hybridus L. Amaranthus hybridus Vell. A brief comparison of major agronomic traits between A.hyp_K_white and Plainsman (Supplementary Figure S1) is shown in Supplementary Table S3. doi: 10.1002/0471250953.bi0411s48, Caselato-Sousa, V. M., and Amaya-Farfán, J. Grain amaranths produce highly nutritional grains with a multitude of desirable properties including C4 photosynthesis highly sought-after in other crops. SNAP (Korf, 2004) and Augustus were also used to predict gene models and used in the subsequent rounds of MAKER (Campbell et al., 2014). Amaranthus hybridus var. 14, 155–167. Also, morphological features like stem solidness and total height at maturity as mentioned by Malligawad and Patil (2010) and seed size (Figure 2F) supports this classification. Introduction. Amaranthus is part of the Amaranthaceae that is part of the larger grouping of the Carophyllales. Popped Amaranth is added to bread, tofu or meat. 12:e1006500. ... Amaranthus caudatus, Amaranthus cruentus, and Amaranthus hybridus (Lightfoot et al., 2017). This assembly was improved using HiC data from Painsman (Lightfoot et al., 2017) to obtain an assembly with a L50 of 99 (column 3, Table 1). Amaranthus caudatus Baker & Clarke, in Dyer Amaranthus chlorostachys Willd. Amaranthus hybridus f. aciculatus Thell. Also, assisted assembly of closely related species significantly improved the contiguity of low coverage mammalian assemblies (Gnerre et al., 2009). doi: 10.1073/pnas.1107739108, Skinner, M. E., Uzilov, A. V., Stein, L. D., Mungall, C. J., and Holmes, I. H. (2009). We utilized a combination of Pacific Biosciences long-read sequencing and chromatin contact … Recently, a chromosome level genome of Lates calcarifer was assembled from a draft genome using long-read sequencing, transcriptome data, optical/genetic mapping and synteny to two closely related seabasses (Vij et al., 2016). SPD: classification, characterization and writing of the manuscript. State of knowledge on amaranth grain: a comprehensive review. 215, 403–410. Basic local alignment search tool. 1849. Avaliable at: http://www.repeatmasker.org. At K = 4, a significant component of A. quitensis is found in all four species. (A) Gene expression profile of 12 genes involved in lysine biosynthesis pathway across different developmental stages (15, 20, 25, and 30 days) of different tissues (Rt, root; St, stem; L, leaf; Bud, Flwr, Flower; YSe, young seed; and MSe, mature seed). The two assemblies obtained were then merged together using Quickmerge (Chakraborty et al., 2016). Interestingly, this germplasm includes seeds from many amaranth landraces from South Asia including India. Amaranth is added as an ingredient in pasta, bread, instant drinks, baby’s food, etc. The database is built using HTML5, bootstrap and JavaScript. PLoS Comput. Also, the read depth considered during variant calling was restricted using samtools mpileup to 10 to match the depth of GBS data (Li et al., 2009). However, according to our classification with 271,305 SNPs, by combining GBS and WGS data, we reproduce the observation made by Wu and Blair (2017). Amaranthus hybridus was originally a pioneer plant in eastern North America. J. Hum. 10:R88. All three trees in Figure 3 suggest that A.hyp_Plainsman_PI558499 (red star) is distal to the clade belonging to A.hyp_K_white (green star). This is an open-access article distributed under the terms of the Creative Commons Attribution License (CC BY). The landrace A.hyp_K_white is currently being used to identify mutations in targeted loci for a given desirable phenotype from a germplasm collection using eco-TILLING and to discover novel mutations that result in desirable traits like determinate growth, enhanced seed yield, seed lysine content and oil content using TILLING-based approaches. The resultant VCF files were merged and based on the presence or absence of SNPs, a binary matrix was constructed from which a phylogenetic tree was obtained as mentioned above. Fast gapped-read alignment with Bowtie 2. However, A.hyp_Plainsman_PI599488 clusters in a distal clade with A.hyp_Mexico_PI511731 in both Figures 3B, 4A as expected because Plainsman is a cross between A. hypochondriacus from Mexico and A. hybridus from Pakistan (Guillen-Portal et al., 1999). doi: 10.1371/journal.pcbi.1007273, Gnerre, S., Lander, E. S., Lindblad-Toh, K., and Jaffe, D. B. Amaranthus shows a wide variety of morphological diversity among and even within certain species. Since GBS only covers 10% of the genome, there is a need to normalize the variants from WGS data for comparison. For improving the agronomic traits of grain amaranth and for the transfer of desirable traits to dicot crops, a reference genome of a local landrace is necessary. One microgram and 10 μg of the DNA were used for the preparation of Paired-End (PE) and Mate-Pair (MP) libraries, respectively. The accession PI490752 originally classified as A. hypochondriacus now classifies under A. quitensis. doi: 10.1093/bioinformatics/btq033. *Correspondence: Subhashini Srinivasan, ssubha@ibab.ac.in; Bibha Choudhary, vibha@ibab.ac.in, †These authors have contributed equally to this work, Front.
