Fig 1. Genetic diversity of the banana pathogen F. oxysporum f. sp. cubense.
Genotyping-by-sequencing analyses of the hitherto identified 24 vegetative compatibility groups (VCG) in F. oxysporum f. sp. cubense resulted in 12,978 DArTseq markers that divide Foc into two distinct clades—clade 1 and clade 2. VCG01216 is considered the same as VCG01213 [13]. The labels for race 1 isolates are based on personal communications with I. Buddenhagen and M. Dita. Although VCG01213 contains all TR4 isolates that cause the current Panama disease epidemic in Cavendish bananas, VCG0120—which has also been considered as race 4 [5]—and VCG0124 [36] have also been recovered from symptomatic Cavendish plants.
