Effector Triggered Susceptibility and Immunity in Bacterial Diseases of Leaf Blight and Streak in Rice

Rice
Rice (Oryza sativa), a staple crop for over half of the global population, is significantly threatened by bacterial blight (BB) and bacterial leaf streak (BLS), caused by Xanthomonas oryzae pv. oryzae (Xoo) and X. oryzae pv. oryzicola (Xoc), respectively.

Molecular mechanisms of pathogenesis in pathovars of the rice pathogenic bacterial species Xanthomonas oryzae [PDF]

, 2005
The pathogenicity of the two closely related phytopathogens Xanthomonas oryzae pv. oryzae and Xanthomonas oryzae pv. oryzicola was studied. These bacteria cause two different diseases with distinct tissue specificities on the same host plant rice. First,

Antimicrobial Activity of UV-Induced Phenylamides from Rice Leaves

Molecules, 2014
Rice produces a wide array of phytoalexins in response to pathogen attacks and UV-irradiation. Except for the flavonoid sakuranetin, most phytoalexins identified in rice are diterpenoid compounds.

Variation suggestive of horizontal gene transfer at a lipopolysaccharide (lps) biosynthetic locus in Xanthomonas oryzae pv. oryzae, the bacterial leaf blight pathogen of rice

BMC Microbiology, 2004
Background In animal pathogenic bacteria, horizontal gene transfer events (HGT) have been frequently observed in genomic regions that encode functions involved in biosynthesis of the outer membrane located lipopolysaccharide (LPS). As a result, different
