Raffinose family oligosaccharides (RFO), raffinose and stachyose, accumulating during seed development are thought to play some role in desiccation tolerance of seeds. However, functions of RFO in drought tolerance of plants have not been elucidated. Sugar analysis showed that drought-, high-salinity- and cold-treated Arabidopsis plants accumulate a large amount of raffinose and galactinol, but not stachyose. This suggests that raffinose and galactinol are involved in the tolerance to drought, high-salinity and cold stresses. Galactinol synthase (GolS) catalyzes the first step in the biosynthesis of RFO from UDP-galactose. We identified three stress-responsive GolS genes (AtGolS1, 2 and 3) among 7 Arabidopsis GolS genes. Overexpression of AtGolS2 in transgenic Arabidopsis caused an increase in endogenous galactinol and raffinose, and showed reduced transpiration from leaves to improve drought tolerance. Microarray analysis did not reveal any genes that are significantly upregulated or downregulated in the AtGolS2-overexpressing plants, which suggests that galactinol and raffinose do not function as signaling molecules but funtion as osmoprotectants.
