Abstract:
The population structure of Fusarium oxysporum f.sp. radicis-lycopersici (F.o.r.l.), the causal agent of crown and root rot disease in tomato, was studied using the vegetative compatibility grouping approach. Four vegetative compatibility groups (VCGs) were identified among 37 isolates from the UK, the Netherlands, Belgium and France. Three of these VCGs (0090, 0091, 0094) had already been described, whereas VCG 0097 was new. VCG 0094 was dominant in the UK, the Netherlands and Belgium, but not in France. The opposite was true for the cosmopolitan VCG 0091, while the cosmopolitan VCG 0090 was only found in France. Based on hyphal interactions, VCG 0094 was divided into three subgroups, each comprising isolates from at least two countries. One isolate of VCG 0094 did not belong to any of these subgroups, suggesting further variability in this VCG. Isolate FORL-19R from France, previously assigned to VCG 0090 I, was reassigned to VCG 0090 III, a new subgroup of VCG 0090 found in Israel. FORL-19R and additional members of its subgroup manifest cross-VCG compatibility between VCG 0090 and VCG 0092. Along with previous studies, the multiple VCGs and subgroups found among F.o.r.l. in western Europe demonstrate a high level of genetic diversity in this pathogen.
