Abstract
Legumes are important clade of commercially important family Leguminosae that mainly include medicinal, flowering and edible plants. Although the genomic sequence of legumes is accessible, only the limited number of effective simple sequence repeat markers has been identified by prior research. Additional polymorphic simple sequence repeats marker discovery will aid in the genetics and breeding of legumes. In this study, 13 complete genome sequences were screened for the identification of chromosome-wise simple sequence repeats (SSRs) and 1,866,861 SSRs were identified. Based on the study, it was observed that the number of SSRs in non-coding region was more as compared to coding region and frequency of mononucleotides was highest followed by di-nucleotides while penta- and hexa-nucleotide repeats were least frequent one. The identified genome-wide SSRs and newly developed SSR markers, primers and their mapping will provide a powerful means for genetic researches across Leguminosae plants, including genetic diversity and evolutionary origin analysis, fingerprinting, QTL mapping and marker-assisted selection for breeding as well as comparative genomic analysis studies.
