“…Cr_10687 is orthologous to RPM1 gene, well known for conferring resistance against bacterial leaf spot caused by Pseudomonus syringae pv. maculicola 43 . Of the remaining 16 genes of total 120 RGHs, 3 genes were not found in the cultivated chickpea assemblies, 3 genes showed large deletions in the wild species as compared to the corresponding genes in the cultivated species and 10 genes showed deletion in the wild chickpea assembly due to the presence of ambiguous bases (N).…”

Cicer reticulatum L. is the wild progenitor of the fourth most important legume crop chickpea (C. arietinum L.). We assembled short-read sequences into 416 Mb draft genome of C. reticulatum and anchored 78% (327 Mb) of this assembly to eight linkage groups. Genome annotation predicted 25,680 protein-coding genes covering more than 90% of predicted gene space. The genome assembly shared a substantial synteny and conservation of gene orders with the genome of the model legume Medicago truncatula. Resistance gene homologs of wild and domesticated chickpeas showed high sequence homology and conserved synteny. Comparison of gene sequences and nucleotide diversity using 66 wild and domesticated chickpea accessions suggested that the desi type chickpea was genetically closer to the wild species than the kabuli type. Comparative analyses predicted gene flow between the wild and the cultivated species during domestication. Molecular diversity and population genetic structure determination using 15,096 genome-wide single nucleotide polymorphisms revealed an admixed domestication pattern among cultivated (desi and kabuli) and wild chickpea accessions belonging to three population groups reflecting significant influence of parentage or geographical origin for their cultivar-specific population classification. The assembly and the polymorphic sequence resources presented here would facilitate the study of chickpea domestication and targeted use of wild Cicer germplasms for agronomic trait improvement in chickpea.

AgriculturalSciences. He has more than 22 years of research experience in oilseed crop disease management and has significantly contributed in the areas of understanding the host-pathogen interactions, epi demiology, and integrated disease management in sunflower, safflower, sesame, peanut, and rape seed-mustard crops. He has published more than 70 peer-reviewed research papers and 4 books. Dr. Chattopadhyay has to his credit several academic awards and one patent. His significant research achievements include the development of Fusarium wilt-resistant genotypes in safflower, the iden tification of genotypes of Brassica juncea resistant to a mixture of isolates of Albugo candida, the development of a biocontrol agent formulation to reduce the use of fungicides in the management of major diseases of oilseeds (Brassica), and seed treatment (and foliar application) of aqueous bulb extract of Allium sativum for the management of major foliar diseases (Alternaria blight, white rust, powdery mildew, and Sclerotinia stem rot) of mustard.

Indian mustard (Brassica juncea) is an allotetraploid (AABB, 2n = 18), formed by hybridization between the A and B genome diploid Brassica species B. rapa and B. nigra, respectively. Yang et al. (2016) recently sequenced the B. juncea genome and reported a genome size of 954.90 Mb, providing the first Brassica B genome assembly. B. juncea is an important winter season oilseed crop (Kumar, 2012) that is also grown as a condiment crop and as a green vegetable (Rakow, 2004). It is cultivated worldwide, with
