| Popis: | Lima bean, Phaseolus lunatus, is closely related to common bean and is high in fiber and protein, with a low glycemic index. Lima bean is widely grown in the state of Delaware, where late summer and early fall weather are conducive to pod production. The same weather conditions also promote diseases such as pod rot and downy mildew, the latter of which has caused previous epidemics. A better understanding of the genes underlying resistance to this and other pathogens is needed to keep this industry thriving in the region. Our current study sought to sequence, assemble, and annotate a commercially available cultivar called Bridgeton, which could then serve as a reference genome, a basis of comparison to other Phaseolus taxa, and a resource for the identification of potential resistance genes. Combined efforts of sequencing, linkage, and comparative analysis resulted in a 623 Mb annotated assembly for lima bean, as well as a better understanding of an evolutionarily dynamic resistance locus in legumes. |
