Phylogenetic relationships in the Sorghum genus based on sequencing of the chloroplast and nuclear genes

Abstract Sorghum [Sorghum bicolor (L.) Moench] is an important food crop with a diverse gene pool residing in its wild relatives. A total of 15 sorghum accessions from the unexploited wild gene pool of the Sorghum genus, representing the five subgenera, were sequenced, and the complete chloroplast g...
