| avrBs2 allele | Mutation | Position(s)a | Effectb | No. of strains | Representative X. campestris pv. vesicatoria strain |
|---|---|---|---|---|---|
| avrBs2-1 | CGCGC insertion | 1508–1526 | Frameshift | 3 | GM97-157 |
| avrBs2-2 | CGCGC deletion | 1508–1526 | Frameshift | 1 | GM98-38 |
| avrBs2-3 | G to C | 1386 | R403P | 15 | GM98-16 |
| avrBs2-4 | C to A | 1407 | A410D | 1 | GM97-1 |
a
Numbering of nucleotides is according to the work of Swords et al. (34).
b
Amino acids are numbered by assuming initiation of translation at the second Met (codon at nucleotide positions 179 to 181). See the text for details of frameshift mutations.
