-//Bs3// is a dominant resistance gene and not expressed during normal life of the plant. The TAL effector AvrBs3 from //Xanthomonas euvesicatoria//pv. //euvesicatoria// (aka //Xanthomonas campestris// pv. //vesicatoria//) binds to the promoter of //Bs3// and causes expression which results in programmed cell death (Römer //et al//., 2007). //Bs3// encodes an unusual flavin monooxygenase, but it is unknown whether the Bs3 protein has any enzymatic activity. The //bs3// variant has a deletion in the promoter which prohibits binding of AvrBs3 (Römer //et al//., 2007). Instead, //bs3// is triggered by binding of a variant of AvrBs3 with deletions of several repeats that cause it to recognize the modified sequence in the promoter of //bs3 // (Römer //et al//., 2007).
