Since the concentrations of K, Ca, glucose and protein have been shown to annually fluctuate in xylem sap of poplar, a deciduous tree, analysis of the exp ression of genes related to xylem sap substances was performed in root of Poplus maximowiczii, a native poplar in Japan. The homologous gene of K transporter, PmGORK-like1, was expressed constitutively after short day treatment, but the homologous genes fo r Ca transporter, PmACA-like1, and xylem sap proteins, PmXSP24 and PmXSP25 were induced by short day treatment and more strongly induced by following low temperature treatment. On the other hand, when the plant grown in long day condition was treated with ABA or low temperature, only PmGORK-like1 was strongly induced in root.

由于白杨木质部汁液中K、Ca、葡萄糖和蛋白质的含量每年都有波动，因此对杨树根中木质部汁液物质相关基因的表达进行了分析。钾转运蛋白同源基因PmXSP 24和PmXSP 25在短日照处理后组成型表达，钙转运蛋白同源基因PmACA-like 1和木质部汁液蛋白同源基因PmXSP 24和PmXSP 25在短日照处理后诱导表达，低温处理后诱导表达更强。另一方面，当长日照条件下生长的植物用阿坝或低温处理时，只有PmK-like 1在根中被强烈诱导。
