The 4.2-kb BamHI fragment from Xoo field isolate PXO2684 does not complement avirulence or aggressiveness functions. (A) The avrXa7 allele from wild-type strain PXO1865, when introduced into Xoo strain PXO99A, confers a HR on IRBB7 whereas the fragment from strain PXO2684 does not. Plasmids containing the avrXa7 alleles (pB1865 and pB2684) were transformed into PXO99A and the transformants were inoculated by infiltration to rice line IRBB7 (Xa7). (B) The 4.2-kb BamHI fragment from PXO1865 restores the ability to elicit strong water-soaked lesions to KL7M, which harbors a mutation in avrXa7, whereas the fragment from PXO2684 does not.
