There is now ample evidence that plant development, responses to abiotic environments, and immune responses are tightly intertwined in their physiology. Thus optimization of the immune system during evolution will occur in coordination with that of plant development. Two alternative and possibly complementary forces are at play: genetic constraints due to the pleiotropic action of players in both systems, and coevolution, if developmental changes modulate the cost-benefit balance of immunity. A current challenge is to elucidate the ecological forces driving evolution of quantitative variation for defense at molecular level. The analysis of natural co-variation for developmental and immunity traits in Arabidopsis thaliana promises to bring important insights.
现在有充分的证据表明，植物的发育、对非生物环境的反应和免疫反应在生理上是紧密交织在一起的。因此，免疫系统在进化过程中的优化将与植物发育的优化协调进行。有两种替代的、可能互补的力量在起作用：由于两个系统中参与者的多效性作用而导致的遗传限制，以及如果发育变化调节免疫的成本效益平衡，就会发生共同进化。当前的一个挑战是阐明驱动分子水平防御的数量变异进化的生态力量。对拟南芥发育和免疫特性的自然协变分析有望带来重要的见解。
