The gene xa5 provides race-specific resistance to X. oryzae pv. oryzae, and encodes the small subunit of transcription factor IIA. How xa5 functions in bacterial blight resistance is not well understood, and its recessive gene action is disputed. Here we show that xa5 is inherited in a completely recessive manner and the susceptible allele Xa5 is fully dominant.

The resistance phenotype was stably transmitted to T1 progeny and inherited as a single locus. The T1 progeny were tested for resistance to 32 X. oryzae pv. oryzae isolates from eight countries. Both the engineered line and the donor line showed resistance to 29 isolates and susceptibility to three isolates. The identical resistance spectrum of both lin…
