Genetic structure analysis of Lasiodiplodia theobromae, based on microsatellite data. Bar plots representing the genetic structure of L. theobromae populations as inferred by different clustering methods: (A and E) DAPC analysis; (B, C, F and G) Structure analysis; and (D) GENELAND analysis. Each vertical line represents an individual, with colours indicating cluster membership. Panels A-D show clustering by host species, while panels E-G show clustering by infected sites. The Structure analysis is presented with two different optimal K values (B, C and F, G) to illustrate potential substructure.
