摘要: 花色对吸引传粉者具有非常重要的作用。自然界的花色具有多样性,主要包括色调和着色模式的变异。虽然前人对花色变异的物质和遗传基础做了大量的研究,但许多花色变异模式特别是着色模式的分子机制还不清楚。传粉者与非传粉者因素介导的自然选择对花色表型变异的选择机制也有许多未解之谜。本文主要对已知花色表型变异的分子机制及自然选择对花色表型的选择作用进行综述,以便进一步地探索花色多样性存在的机制和自然选择对花色进化方向的影响。

Abstract: Flower color plays a key role in attracting pollinators, and a staggering variety of flower color variations including color parameters and pigmentation pattern exist in nature. Though many studies have been done on the molecular mechanisms of flower color variation, there is still much unknown, especially for pigmentation pattern. The contributions of pollinator and non-pollinator agents to natural selection on floral color variation are also unclear. The review discusses recent data on genetic mechanisms and natural selection of flower color variation. The summary may as-sist us to further analyze molecular mechanisms of flower color diversity and role of natural se-lection in flower color variation.
