Other claims from this paper (11)
- Observation The isolates belonged to five blast races.
- Method / resource Rep-PCR classified the isolates into 15 groups.
- Observation Each blast race had a predominant Rep-PCR group.
- Observation IB17, IC17 and most IA1 and IB1 isolates were avirulent to Katy but virulent to M202.
- Mechanism The authors attributed resistance in Katy to Pi-ta.
- Observation AVR-Pita1 did not amplify from 28 virulent isolates.
- Observation A single AVR-Pita1 allele amplified in 78 avirulent isolates.
- Observation Different AVR-Pita1 alleles were present in each of 12 avirulent isolates.
- Observation Sequence analysis found ten AVR-Pita1 haplotypes, four new.
- Observation New variants had 12 amino acid changes relative to the first described AVR-Pita sequence.
- Mechanism Altered AVR-Pita1 in isolates from rice with and without Pi-ta suggested field adaptation.
