摘要
山梨醇是蔷薇科植物主要的光合产物和转运物质,人们对其代谢转运进行了大量研究。山梨醇相关基因转入非蔷薇科植物中,可以提高其抗逆性;在植物离体培养中添加山梨醇可以广泛地、明显地提高愈伤组织的分化和再生能力,但是,对于其促进分化再生的机理尚不明确。概述了近年来山梨醇在植物研究中取得的进展,以期为认识山梨醇代谢途径、创建高效组培技术以及明确山梨醇在组培中的作用机理提供参考。
Sorbitol is the major photosynthetic products and transport materials in rosaceous plant , a lot of works had done on the metabolism and transportation.Meanwhile, some studies showed that sorbitol-related genes into the non-rosaceae could increase its stress resistance. In recent years, a large number of studies indicated that adding sorbitol into plant tissue culture could widely and significantly improve differentiation regeneration , however, the mechanism of that is not clear.This paper summarized the research progress about sorbitol in plants in recent years , it could provide references for understanding sorbitol metabilism pathway , creating highly efficient techniques of plant tissue culture and study the mechanism of sorbitol in tissue culture.
