Abstract

Given that plants are sessile organisms, traits involved in adapting to local environments and/or in monitoring the surrounding environment, such as having photoreceptors, are significant targets of natural selection in plant evolution. To assess the intraspecific adaptive evolution of photoreceptors, we investigated sequence variations in four phytochrome genes (PHYA-C and PHYE) of Cardamine nipponica (Brassicaceae), an endemic Japanese alpine plant. The genealogies of haplotypes and genetic differentiations showed inconsistent patterns of evolution across phytochromes, suggesting that evolutionary forces were distinct in phytochromes of C. nipponica. An overall low level of nucleotide diversity in phytochrome genes suggests that the evolution of phytochromes is constrained by purifying selection within C. nipponica, which is consistent with previous findings on phytochromes. However, PHYE alone exhibited a non-neutral pattern of polymorphisms (Tajima's D= 1.91, P
