Function
Blast is a very common disease found in rice. Blast causes immense damage to rice in rice-growing countries .And Pi9 alleles are mainly responsible for resistance to rice blast. We can use Pi1 and pi2 to improve the resistance ability to blast through hybridization.
The rice disease blast, caused by the fungus Magnaporthe oryzae, is one of the most devastating diseases afflicting the rice crop [1]and is best combated by the deployment of genetic resistance [2].
Expression
editing We test the relationship between Pi1,Pi2 and D12 gene in expression. When Pi1,Pi2 and D12 gene unit together, they will improve the resistance to blast by a great deal in the field condition.Pi9 gene lies on the chromosome6.
Evolution
To evaluate the phylogenetic relationship among the Pi9 alleles, we constructed neighbor-joining trees using the full-length fragment, the NBS region, and the LRR region. The analysis indicated that all these alleles are clustered into the same clade and belong to the same NBS-LRR sub-family. Two obvious haplotypes are distinguishable in the phylogenetic tree. Group I is mainly composed of the Asian cultivated rice O. sativa and its two ancestors, O. nivara, and O. rufipogon. Most of the African cultivated rice O. glaberrima and its ancestor O. barthii are clustered in group II. These results suggest that different selection pressures have occurred in the two unique groups of the Oryza species during domestication and/or natural selection.[3]
Nucleotide Polymorphism of the Pi9 Alleles
Of 2,927 nucleotides, 435 polymorphic sites including alignment gaps (∼18.9%) were detected among the 40 sequences using the DnaSP program. An intermediate-diversified nucleotide diversity (π=0.03348, P=0.000293) for the Pi9 alleles was observed based on the previously published criteria (Yang et al. 2008). The average nucleotide diversity of the LRR region (π=0.04554, P=0.00354; θ=0.04307, P=0.01263) is much higher than that of the NBS region (π=0.02098, P=0.00194; θ=0.02746, P=0.00816) (Table 2; Fig. 2). Both values are similar in cultivated rice and wild rice groups (Table 2; Fig. 2). These results suggest that the LRR domain is important in the variation of the Pi9 alleles.
