Arabitol is a five-carbon polyol, it is produced by osmophilic yeast species. It has been studied extensively, that accumulation of arabitol in cell takes place under stress conditions in yeast and other fungal species suggesting it protects cell from drought and salinity stress.In yeast, arabitol dehydrogenase found responsible for the production of arabitol from ribulose-5-phosphate. All plants synthesize ribulose-5-phosphate via pentose pathway in chloroplasts. The result of this study suggests that this gene could be expressed in crop plants to withstand abiotic stresses.
