植物体内糖分子的长距离运输及其分子机制

植物学报 2015年第1期50卷 107-121页

作者：张懿张大兵刘曼上海交通大学生命科学技术学院上海200240 上海瑞丰农业科技有限公司上海201106

植物器官(如叶、叶鞘、绿色的茎等)可以通过光合作用将CO2合成为碳水化合物,并经过长距离运输到达库组织(如新生组织、花粉、果实等)中进行贮存或利用。蔗糖是高等植物长距离运输碳水化合物的主要形式。蔗糖分子从源到库的运输包括源组... 详细信息

植物器官(如叶、叶鞘、绿色的茎等)可以通过光合作用将CO2合成为碳水化合物,并经过长距离运输到达库组织(如新生组织、花粉、果实等)中进行贮存或利用。蔗糖是高等植物长距离运输碳水化合物的主要形式。蔗糖分子从源到库的运输包括源组织韧皮部的装载、维管束的运输和库组织韧皮部的卸载3个步骤。遗传学和分子生物学研究证明,蔗糖转运蛋白、转化酶和单糖转运蛋白在糖分子的装载和卸载过程中发挥重要作用。该文综述了目前对光合产物运输过程及其调控分子机制的最新研究进展。

Genetic variation, including agronomic trait variation, often occurs in somatic cell culturing. In this study, we compared the main agronomic traits of two rice mutants, M3 and M14, which were derived from Shenxiangjing 5 somatic cell culturing. Significant differences were found between the two mutants and the wild rice Shenxiangjing 5 (Table 1). Results were as follows:1. Compared with Shenxiangjing 5, the mutant had higher plant and longer panicle.

MADS-box蛋白可以通过形成多聚体复合物发挥功能。Os MADS34作为一个多样功能的SEPALLATA（SEP）基因,其可以控制水稻花序及小穗的发育。为了了解Os MADS34在控制水稻花序及花发育的机理,我们利用水稻Os MADS34作诱饵蛋白,从构建的水稻枝梗分生组织的c DNA文库中筛选可以互作的未知蛋白。利用酵母双杂交分析,筛选到了互作蛋白Os MADS56,并通过自激活验证及蛋白定位分析降低了假阳性及假阴性的因素影响。利用定量PCR对Os MADS56的表达模式进行分析,Os MADS56在水稻花序和小穗发育时期表达,Os MADS56可能是在蛋白水平上与Os MADS34相互作用共同调控水稻花序的发育。本工作为今后进一步研究Os MADS34及开花基因如何调控水稻花序和花发育提供了见解。
