摘要: The bacterial blight gene locus Xa 27 in rice has two striking differences in the presumed promoter-raised resistant/susceptible allele expression. We used a functional marker targeting the 25 deletion at 18 bp upstream of the putative TATA box and assayed the allelic status at Xa 27 in 572 rice genotypes. The alleles evaluation obtained from 191 cultivars tested may contribute to little information of the resistance specificity associated with allele diversity. The allele frequency associated with complete resistance in the indica was different from that associated with complete resistance in the japonica.
