A Cf-9 Mutant Carrying the Specificity Determinants of Cf-4 Confers Recognition of AVR4.
The specificity of mutant 37, which confers full AVR9 recognition upon transient expression in tobacco (Figure 2A), was changed into specificity for AVR4 by deleting LRRs 11 and 12 and introducing W389, G411, and F457, resulting in mutant 367. For further details, see legends to Figures 1 and 2.
