Small GTPase of the Rab family functions as molecular switch in vesicle trafficking, regulated by guanine nucleotide exchange factors (GEFs) and GTPase-activating proteins (GAPs). In our ongoing efforts to study the pathogenesis of Colletotrichum fructicola, the causal agent of anthracnose in edible-oil plant Camellia oleifera, we identified CfRab6 as the Rab GTPase and characterized its roles in C. fructicola. Consistent with our hypothesis, targeted gene deletion revealed that the ΔCfrab6 mutant displays defects in vesicle trafficking, inclu...
