The resistance is rapidly overcome in the field by mutation of //avrBs1// in the bacteria making this resistance unsuitable for commercial breeding.

 === Brief description === === Brief description ===

 +The dominant //Bs2// resistance gene encodes an NB-LRR protein which interacts with the AvrBs2 protein from //Xanthomonas euvesicatoria //pv. //euvesicatoria// (aka //Xanthomonas campestris //pv. //vesicatoria//)and causes a hypersensitive response (Tai //et al//., 1999). Expression of //Bs2// in other solanaceous plants, but not nonsolanaceous plants, also triggers hypersensitive response to AvrBs2. //Bs2// was broadly used in resistance breeding and in 2000 nearly 100% commercial bell peppers contained the //Bs2// resistance. Because pathogen strains with mutations in //avrBs2// emerged, //Bs2// was only effective for commercial control of bacterial spot disease for 5-6 years.

 +//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). The TALE AvrHah1 from //Xanthomonas gardneri// also elicits the //Bs3// resistance. Commercial pepper lines containing //Bs2// and //Bs3// were used.
