Application

Application	Comment	Organism
agriculture	in seeds of the galactinol synthase GS1/GS2 and raffinose synthase RFS5 mutant the timing of desiccation tolerance acquisition is delayed as compared to wild type. Seeds from GS1/GS2 overexpressing plants with high levels of galactinol, raffinose, and stachyose, and RS5 overexpressing plants possess more raffinose and stachyose but less galactinol compared to wild type. These lines show greater germination percentage and shorter time to 50% germination after desiccation treatment at 11 and 15 days after flower. The role of raffinose family oligosaccharides is time limited and mainly affects the middle stage of seed development by enhancing seed viability and the ratio of GSH to GSSH in cells, but there is no significant difference in desiccation tolerance of mature seeds	Arabidopsis thaliana
