Molecular basis of productivity improvement through sink development of potato

本研究旨在阐明马铃薯源器官促进光合作用和库器官积累淀粉的机理。该基因是RanGTdR家族的一员。以马铃薯带腋芽的外植体为材料，建立了匍匐茎诱导体系，并对两个RanGT基因的表达进行了分析。结果表明，在匍匐茎诱导的初始阶段，两个内源基因中的一个被专门诱导。

This study was done to clarify the mechanism of promotion of photosynthesis in the source organ and accumulation of starch in the sink organ in potato plants. The gene was a member of the RanGTPase family. We established the in vitro stolon induction system using potato expalnts with axillary buds to analyze the expression of two RanGTPase genes. The results showed clearly that one of the two endogenous genes was exclusively induced in the initial phase of the stolon induction.
