重复的表型进化可以发生在种间和种内水平，在驯化植物中尤其突出，人工选择有利于许多不同物种和品种的相同性状。重复进化是由于每个谱系中相同还是不同基因的变化引起的问题，现在可以利用在各种作物中鉴定出的驯化和改良基因来解决。在这里，我们记录的遗传基础的nonpigmented（“白色”）果皮在驯化的非洲水稻（Oryza glaberrima）和比较它与已知的遗传基础相同的性状在驯化的亚洲水稻（Oryza sativa）。在某些情况下，非洲水稻的白色果皮是由于Rc基因的独特突变造成的，而Rc基因也控制着亚洲水稻的果皮颜色变异。在一种情况下，白色果皮似乎是由于在不同的基因或潜在的顺式调控区域的变化。
Repeated phenotypic evolution can occur at both the inter-and intraspecific level, and is especially prominent in domesticated plants, where artificial selection has favored the same traits in many different species and varieties. The question of whether repeated evolution is due to changes at the same or different genes in each lineage can now be addressed using the domestication and improvement genes that have been identified in a variety of crops. Here, we document the genetic basis of nonpigmented (‘white’) pericarps in domesticated African rice (Oryza glaberrima) and compare it with the known genetic basis of the same trait in domesticated Asian rice (Oryza sativa). In some cases, white pericarps in African rice are due to unique mutations at the Rc gene, which also controls pericarp color variation in Asian rice. In one case, white pericarps appear to be due to changes at a different gene or potentially a cis-regulatory region.
