* Yeast two-hybrid based analyses identified a putative regulator of sugar metabolism, SNF1-related kinase 1 (SnRK1), as an interactor of AvrBsT (Szczesny //et al//., 2010). Gene silencing experiments revealed that SnRK1 is required for the induction of the AvrBs1-specific HR, which is suppressed by AvrBsT (Szczesny //et al//., 2010). Thus, SnRK1 may be involved in the AvrBsT-mediated suppression of the AvrBs1-specific HR (Szczesny //et al//., 2010). | * Yeast two-hybrid based analyses identified a putative regulator of sugar metabolism, SNF1-related kinase 1 (SnRK1), as an interactor of AvrBsT (Szczesny //et al//., 2010).
