虫蛀对植物代谢产物分布的影响因植物基因型而异。在这项研究中，两个桉树基因型具有不同的电阻水平，和几个初级和次级代谢产物的水平，以及植物激素的虫瘿和无虫瘿部分的虫瘿叶由瘿蜂Leptocybe invasa，和无虫瘿（对照）叶片进行了比较。结果发现，两种植物基因型的虫瘿积累较高浓度的碳，总酚，赤霉素（GA），脱落酸（阿坝），但有较低的叶绿素含量比未虫瘿部分。高感基因型的虫瘿中氮、细胞分裂素、赤霉素和叶绿素含量高于低感基因型，而碳氮比、总酚、单宁和阿坝含量低于低感基因型。两种基因型的虫瘿和未虫瘿部位的阿坝含量均高于相邻对照叶片。与对照相比，高感基因型的CK和GA含量在虫瘿中增加，而在无虫瘿部分降低。对于不太敏感的基因型，CK水平增加的虫瘿和未虫瘿部分与对照叶相比，但较高水平的单宁，总酚，和GA只检测到虫瘿。因此，我们的研究发现，没有足够的证据表明，这些代谢物和植物激素的分布的影响，扩展到受攻击的叶片，因为他们有很大的差异，植物基因型。
Impacts of galling on the distributions of plant metabolites can vary greatly with plant genotype. In this study, two Eucalyptus genotypes with different resistance levels were chosen, and the levels of several primary and secondary metabolites, as well as phytohormones in galls and ungalled portions of galled leaves infested by the gall wasp Leptocybe invasa, and gall-free (control) leaves were compared. It was found that galls of both two plant genotypes accumulated higher concentrations of carbon, total phenolics, gibberellins (GA), and abscisic acid (ABA) but had lower chlorophyll content than ungalled portions. However, galls of highly susceptible genotype contained higher nitrogen (N), cytokinins (CK), GA, and chlorophyll content but lower C/N ratio, total phenolics, tannins, and ABA than less susceptible genotype. For both two genotypes, ABA in galls and ungalled portions increased compared with adjacent control leaves. CK and GA levels increased in galls but decreased in ungalled portions of highly susceptible genotype, compared with control leaves. For less susceptible genotype, CK levels increased in both galls and ungalled portions compared with control leaves, but higher levels of tannins, total phenolics, and GA were only detected in galls. Therefore, our study found insufficient evidence that the impact of galling on the distributions of these metabolites and phytohormones extended beyond the attacked leaves, because they varied greatly with plant genotype.
