项目摘要
Some plants can tolerate herbivory and tissue damage without reductions in fitness (or yield), yet we know very little about the evolution and ecology of tolerance traits, or even the mechanisms involved in plant compensatory ability. Moreover, we still lack a basic understanding of whether the two components of plant defense against herbivores – resistance (avoiding being eaten) and tolerance (enduring being eaten) – differ in their ecological and evolutionary relationships to plant growth and reproduction. This is despite the fact that the expression and fixation of tolerance responses within plant populations may have immense ecological consequences, e.g. through decreasing the effectiveness of biocontrol agents for invasive weeds, or supporting a more diverse insect community in crops. Indeed, theory suggests that tolerance of herbivory may fundamentally differ from plant resistance in its effects on the population dynamics of insect herbivores and their natural enemies, e.g by avoiding the evolutionary arms race typical in plant-insect resistance evolution. A greater understanding of plant tolerance traits and impact could not only resolve some of the outstanding ecological and evolutionary questions around variation in plant defense and specificity in plant-insect interactions, but also produce an actionable target for plant improvement and protection programs.
一些植物可以在不降低适合度(或产量)的情况下耐受食草性和组织损伤,但我们对耐性性状的进化和生态,甚至对植物补偿能力所涉及的机制知之甚少。此外,我们仍然缺乏对植物抵御食草动物的两个组成部分--抵抗(避免被吃)和耐受(忍受被吃)--的基本了解,它们与植物生长和繁殖的生态和进化关系是否不同。尽管在植物种群中表达和固定耐性反应可能会产生巨大的生态后果,例如通过降低生防剂对入侵杂草的有效性,或者支持作物中更多样化的昆虫群落,但这一点仍然存在。的确,理论表明,食草动物的耐受性可能与植物抗性的根本不同之处在于它对食草动物及其天敌的种群动态的影响,例如通过避免植物-昆虫抗性进化中典型的进化军备竞赛。深入了解植物耐受性状及其影响,不仅可以解决植物防御变异和植物-昆虫相互作用中的特异性等突出的生态学和进化问题,而且还可以为植物改良和保护计划提供一个可行的目标。
