基于防御分配的生理和生态成本，大多数植物防御理论预测不同类型的反草食动物防御的资源投入之间会发生权衡。为了检验这一预测，我们对 1976 年至 2002 年发表的 31 项研究进行了荟萃分析，这些研究提供了植物基因型中不同防御性状的共变数据。我们发现植物不同防御性状之间没有总体负相关；相反，防御特征之间的关系根据同时发生的防御类型从积极到消极变化。仅在本构防御和诱导防御之间发现了权衡的证据。因此，在很大程度上，植物似乎是多才多艺、多才多艺，可以成功地产生多种类型的防御，而无需付出相当大的代价。因此，我们的调查几乎没有提供证据表明防御性状之间的遗传权衡显着限制了植物多重防御的进化。
On the basis of physiological and ecological costs of defense allocation, most plant defense theories predict the occurrence of trade-offs between resource investment in different types of anti-herbivore defenses. To test this prediction, we conducted a meta-analysis of 31 studies published in 1976-2002 that provided data on covariation of different defensive traits in plant genotypes. We found no overall negative association between different defensive traits in plants; instead, the relationship between defensive traits varied from positive to negative depending on the types of co-occurring defenses. Evidence of trade-off was found only between constitutive and induced defenses. Therefore, to a large extent, plants appear to be jacks-of-all-trades, masters of all and may successfully produce several types of defense without paying considerable trade-offs. Our survey thus provides little evidence that genetic trade-offs between defensive traits significantly constrain the evolution of multiple defenses in plants.
