摘要

病原菌侵染引发植株防卫基因表达的信号传导途径水杨酸途径(SA)与虫害(机械损伤)诱发的植物防御信号传导途径茉莉酸途径 (JA)会同时存在,且两种信号途径间存在着相互抑制的拮抗作用。本试验结果表明,水稻植株受到纹枯病菌侵染之后,褐飞虱在RH的感病植株和健康植株中明显倾向于选择感染纹枯病菌的RH水稻植株;但在不同水稻品种上的取食行为以及蜜露排泄量及蜜露氨基酸含量的测定均未发现褐飞虱对于感染纹枯病的抗、感水稻品种有显著的取食趋性。说明抗、感褐飞虱的水稻品种感染纹枯病之后并未显现出更易感虫的性状。

Abstract

There are antagonistic effects between salicylic acid pathway (SA), signal transduction pathway of plant defense gene expression induced by pathogen infection, and jasmonic acid pathway (JAA), plant defense signal transduction pathway induced by insect pests. The results showed that the brown planthopper(BPH) tended to feed on Rathu Hennati (RH) infected with Rhizoctonia solani in Y-tube olfactometer; while electrical penetration graph data, honeydew excretion and contents of amino acids in honeydew were not shown the BPH trend to Rathu Hennati(RH) and Taichung Nativel(TN1) treated with Rhizoctonia solani. It indicated that the presence of Rhizoctonia solani had no significant impact on BHP feeding selectivity.
