| Outline of Final Research Achievements |
Phospholipids-based signaling cascades are common signal transduction mechanisms in plant immune responses. We have been identified genes related to phospholipid turnovers from Nicotiana benthamiana. The SEC14 phospholipid transfer protein (NbSEC14)-silencing compromised jasmonic acid (JA)-dependent immune responses. Activities of phospholipase C and D, and the synthesis of phosphatidic acid (PA) was significantly reduced in NbSEC14-silenced plants. The NbSEC14-silencing compromised pathogen associated molecular patterns (PAMPs)-triggered immune responses and basal defense against Ralstonia solanacearum and Pseudomonas syringae. Among the reported PA-target proteins, we found that respirotary burst oxidase homolog B, phosphoinositide dependent proteinkinase 1 and sucrose non-fermenting 1 related kinase are closely related to immune responses.
