摘要:
植物激素作为信号分子，在调控水稻生长和免疫中发挥关键作用。探究水稻早期响应稻瘟菌侵染的激素信号变化对于增强水稻免疫具有重要意义。以水稻品种CO39和稻瘟病菌Guy11为研究材料，利用代谢组和转录组对水稻早期响应稻瘟病菌侵染的内源激素变化进行分析。结果发现，水杨酸、脱落酸、生长素、赤霉素、茉莉酸和茉莉酸甲酯在稻瘟病菌侵染水稻后含量持续增加，其中茉莉酸、茉莉酸甲酯、生长素在接种72 h大量积累，相对含量分别约为对照组的4.9、9.4、2.4倍。转录组鉴定发现，生长素和茉莉酸相关基因数量最多，且生长素合成途径主要以吲哚乙酰胺(IAM)和吲哚乙醛肟途径(IAN)为主。分别鉴定到9个茉莉酸和8个生长素合成基因在水稻受到侵染后表达量显著增加。本研究结果为深入了解水稻早期响应稻瘟病菌侵染的分子机制提供参考。
