It has been suggested that Japanese oak (Quercus mongolica var. crispula) in the northern and the southern part of Japan had experienced a different history of adaptation during the glacial age migrations and settlements. In order to detect adaptive changes in genes we cloned phytochrome genes in the oak as one of the candidates. We also collected seeds from the northern and the southern parts of Japan and planted in the experimental forest in Sapporo and Ehime to measure phonological traits. We found three phytochrome genes, and also that nucleotide diversity was high in the northern populations. In the field experiment, we observed that there are considerable difference in early death rates and secondary flash rates in the northern and the southern populations.

有人认为，日本北部和南部的日本橡树（Quercus mongolica var. Crisula）在冰河时代的迁徙和定居过程中经历了不同的适应历史。为了检测基因的适应性变化，我们在橡树中克隆了光敏色素基因作为候选基因之一。我们还从日本北部和南部收集了种子，并将其种植在札幌和爱媛的实验林中，以测量语音特征。我们发现了三种光敏色素基因，并且北方人群的核苷酸多样性很高。在野外实验中，我们观察到北方和南方人群的早期死亡率和二次闪现率存在相当大的差异。
