Stress Responses to Tomato Yellow Leaf Curl Virus (TYLCV) Infection of Resistant and Susceptible Tomato Plants are Different

摘要: Two genetically close inbred tomato lines, one resistant to Tomato yellow leaf curl virus (TYLCV) infection (R), the other susceptible (S), showed completely different stress response upon TYLCV infection. S plants were stunted and do not yield, while R remained symptomless yielded. Comparison of protein profiles metabolites patterns in infected tomatoes revealed a host response. characterized by higher levels reactive oxygen species (ROS) ROS compounds, anti-oxidative, pathogenesis-related (PR) wound-induced proteins predominant. In contrast, did drastically activate same defense mechanisms as plants, homeostasis was much more effectively maintained chemical chaperones. Sources carbon nitrogen less affected than which could make balanced fit sustain Even though both types contained comparable amounts at specified stage infection, cellular immune responses different. Presented results are preliminary indicate so concrete data but global tender understanding background resistance susceptibility TYLCV.
