Abstract
|
|
|
Xanthomonas oryzae pv. oryzae (Xoo) is the causal agent of bacterial blight on rice. In this paper, current status
on molecular genetic study of major virulence genes, hypersensitive response and pathogenicity (hrp), productions
of extracellular polysaccharide (EPS), extracellular enzymes and lipopolysaccharides (LPS), avr genes
were reviewed. The IS elements with 611 copies including 133 ORF IS were inserted in various regions of the
Xoo genome and in expecially regions franking virulence genes. Whole genome sequence of X. oryzae pv.
oryzae KACC10331 were used for defining genetic organization of the virulence genes. Futhermore, the virulence
genes in Xoo genome were compared to those of other Xanthomonas species in Blast GenBank data
base.
