Gene expression changes induced in Rice (Oryza sativa) leaves following treatment with any one of the following: wild type Xoo, lipopolysaccharide (LPS) and exopolysaccaride (EPS) deficient Xoo mutant; LPS proficient but EPS deficient Xoo mutant

Lipopolysaccharide is a Microbe Associated Molecular Pattern (MAMP) that is known to induce defense responses in plants. In rice we have shown that Xoo LPS induce callose deposition, reactive oxygen production and induced resistance response. The exopolysaccaride (EPS) secreted by Xoo might be involved in supressing these defense responses.
