摘要

植物化学表型的多样化通常与空间和时间上可变的植物-昆虫相互作用有关。花香通常被认为是授粉者介导的选择目标,而叶面化合物则被认为是拮抗剂介导的选择目标。然而,花卉和植株的植物化学物质在生物合成上是相互关联的,因此可能作为综合表型而进化。我们利用一个由 28 个多年生草本植物 Arabis alpina(十字花科)种群组成的共同园地,研究了花香化合物和叶面防御化合物(挥发性化合物和组织结合型葡萄糖苷酸盐)内部和之间的整合。在花香挥发物、叶面挥发性化合物和葡萄糖苷酸盐中,植物化学物质通常呈正相关,而且这些组内的相关性比它们之间的相关性更强。因此,我们没有发现化合物组之间存在整合的迹象,这表明这些化合物组可以自由地独立进化。相对于自交不亲和种群,自交不亲和种群的花香化合物之间的相关性更强,花香和叶面挥发物之间的整合度呈下降趋势。我们的研究是对多种生理上相关的植物性状进行整合的罕见测试,这些性状都是昆虫介导选择的潜在目标。我们的研究结果表明,独立的进化力量有可能使植物化学的不同轴线多样化,而不会受到重大限制。

期刊介绍: New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
