Plants are powerful models for the study of adaptive evolution. Since they are rooted in place, they must directly face environmental insults, making adaptation to local conditions vital. In addition to adaptation to natural conditions, some plant species have held a central role in human subsistence over the past several thousand years. In these species, humans exerted strong selective pressures on traits of agricultural importance. Recently, an increasing number of studies have aimed to identify the genomic basis of adaptation. These studies have provided insights into the mechanisms through which the raw materials of adaptation were introduced as well as the modes of adaptation in wild and domesticated species.
植物是研究适应性进化的有力模型。由于它们扎根于原地，必须直接面对环境侵害，因此适应当地条件至关重要。除了适应自然条件外，在过去几千年里，一些植物物种在人类生存中发挥了核心作用。在这些物种中，人类对具有农业重要性的性状施加了强大的选择压力。最近，越来越多的研究旨在确定适应的基因组基础。这些研究为适应的原材料引入机制以及野生和驯化物种的适应模式提供了见解。
