Phenotype
abscisic acid deficient, ABA and dormancy responses appear to be as expected for aba2; reduced sensitivity to the inhibitory effects of sugars on early seedling development; seeds will germinate and form seedlings with expanded cotyledons and true leaves on concentrations of glucose (0.3M), sucrose (0.3M) and sorbitol (0.4 M) that inhibit these processes in wt plants; very slightly decreased sensitivity to mannose (2mM) on germination and early seedling development; decreased sensitivity to the presence of the GA biosynthesis inhibitor paclobutrazol (35 mg/L); increased rate of water loss (leaf transpiration), which leads to symptoms of wilting and withering especially under low relative humidity and water stress; reduced growth, reduced plant size and vigor; allelic to sis4-1.
