Stabilization of the life cycle of temperate fruit trees under irregular climates - elucidation of the molecular mechanism on water movement and redox regulation in the dormant buds

芽内休眠状态的转变以休眠芽组织中谷胱甘肽含量显着增加为特征。芽中GSH的积累与GSH 1和GSH 2基因以及氧化还原调节酶基因（如交替氧化酶（AOX））的转录模式的主要增加相一致。根据MRI观察的结果，水含量逐渐增加到所需的桃休眠芽活动的结束时，内优势是由于通过水通道蛋白的膜运输特性的细胞间和细胞内的通信。低冷量处理下，日本梨混合芽的水分流动性和含水量均较低，尤其是鳞片。与此相反，增加水的流动性和相对含量，观察到在特定的部分，这是更强调在温和的冬季条件下生长了几个季节的植物的混合芽，导致花原基坏死，和新的花序，这对应于一个不规则的花的形式的发展。

The transition from bud endodormancy state was characterized by a significant increasing on glutathione content in dormant bud tissues. The GSH accumulation in the buds was coincided with major increases in transcript patterns of genes GSH1 and GSH2 and redox regulating enzyme genes such as the alternative oxidase (AOX). According to the findings by MRI observation, a gradual increase in water content to that required for peach dormant bud activity at the end of endodomancy was resulted from inter- and intracell communication through membrane transport properties of aquaporins. And also, the mixed buds of Japanese pear subjected to low chilling accumulation showed low water mobility and water content especially in scales. In contrast, increased water mobility and relative content were observed in specific portions, which was more accentuated in the mixed buds of plants grown for several seasons under mild winter conditions, resulting in the necrosis of floral primordia, and the development of new inflorescences which corresponds an irregular floral form.
