1.Mechanism of ion transport : The gatting mechanism os calcium channel and chloride channel responsible for generton of action potential was analyzed by Ohkawa and Shimmen. Kiyosawa found that osmoregulation of internodal cells of Characeae is disturbed by increasing the concentration of potassium in the external medium. 2.Ion transport in signal transduction : Role of ion transport in regulation of cytoplsmic steaming was analyzed by kikuyama and Takagi. They found that calcium transport across the plasma membrane is playing central role in controlling the cytoplasmic streaming. Mizuno analyzed the mechanism of involvment of proton pump in control of growth in higher plants and Katou mathematically analyzed the relationship between ion transport and growth. Shimazaki and Iino analyzed the mechanism of proton transport, which is regulated by blue light. 3.Ion transport under stress : Oosumi found importance of vacuole and its proton pump in autophagy in yeast. Okazaki and Yoshida found acidification of the cytoplasm in turgor regulation and under low temperature stress, respedtively. Mimura studied homeostasis of phosphate under phsphate deficiency.

1.离子传输机制：Ohkawa和Shimmen分析了钙通道和氯通道参与动作电位产生的门控机制。Kiyosawa发现，增加外部培养基中的钾浓度会干扰烟草科植物节间细胞的光合调节。2.信号转导中的离子转运：kikuyama和Takagi分析了离子转运在调节细胞质蒸汽中的作用。他们发现钙离子跨质膜转运在控制细胞质流动中起着核心作用。水野分析了质子泵参与高等植物生长调控的机理，加藤从数学上分析了离子运输与生长的关系。Shimazaki和Iino分析了质子运输的机制，这是由蓝光调节的。3.压力下的离子运输：Oosumi发现了液泡及其质子泵在酵母自噬中的重要性。Okazaki和Yoshida分别在膨压调节和低温胁迫下发现了细胞质的酸化。Mimura研究了磷酸盐缺乏时磷酸盐的稳态。
