Abstract :
Sesame is one of the oldest oilseed crops grown mainly in Africa and Asia. Although genetic and genomic studies on sesame have started late, the past 5 years have witnessed extensive progresses in these areas on this crop.
Important genomic sequence resources such as functional markers, genes and QTLs linked to agronomically important traits, have been generated through linkage mapping and association analysis to assist sesame improvement programs. However, most of these data are scattered in different maps making them hard to be exploited efficiently in breeding programs. In this study, we report a comprehensive physical map gathering 151 published genomic
sequence resources which highlighted some hotspot functional regions in the sesame genome. Moreover, 83,135 non-redundant SSRs have been supplied along with their physical position and motif composition. This will assist future research in fine mapping or pinpointing more functional genes based on the already published QTLs and functional markers. This physical map represents a good landmark for further non-overlapping genetic and genomic studies working towards sesame improvement.
