+ | Expression analysis | ||
+ | |||
+ | In resistant pepper plants, the promoter of //Bs3// contains a //UPA// box that is bound by AvrBs3 resulting in the transcription of the gene //Bs3//. //Bs3// encodes a protein that is homologous to flavine-dependent mono-oxygenases (Römer //et al//., 2007) and its expression causes rapid cell death thus preventing the spread of the pathogen (Bonas //et al//., 1989; Bonas //et al//., 1991). | ||
+ | |||
+ | The central region of the //avrBs3// gene consists of 17.5 nearly identical 102 bp repeats. Each repeat encodes 34 amino acids (Bonas //et al//., 1989). Repeat variable di-residues (RVDs) at positions 12 and 13 determine the specificity of each repeat (Boch //et al//., 2009; Moscou & Bogdanove, 2009). Rearranging individual repeats enables construction of any desired DNA-binding specificity (Boch //et al.//, 2009). | ||
