| 中文摘要: |
| 植物次生代谢物质从其生物合成途径可以将次生物质分成酚类、类萜、含氮化合物和其他次生物质4大类。 植物次生代谢物质对害虫有忌避和毒杀作用,引诱害虫在寄主上产卵,使其后代有较好生存环境。植物次生物质吸 引传粉昆虫繁衍后代,同时也吸引某些共生生物。植物次生代谢物质在昆虫和植物协同进化中具有信号转递功能。 |
| 英文摘要: |
| Plant secondary metabolites are synthesized by different pathways, such as phenylpropanoid pathway and ter-penoid pathway, which have ecological significance. There are four kinds of plant secondary metabolites, namely pheno-lics, terpenoids, nitrogen compounds and other secondary metabolites according to their biological synthesis pathway. Recognition of plants by insects is due to insects' recognition of chemical mapping mediated by the smell of plants' volatiles. Plant secondary metabolites have repellent and toxic effects on insects, which help insects to find appropriate hosts for oviposition and provide good places for their progenies. Plant secondary metabolites not only attract insects to pollen and thereby help plant propagate, but also attract some symbiotic organisms to where they live together. Plant secondary metabolites transmit signals in the coevolution of insects and plants. |
