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 expandedcotyledons 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; same as sis4-2.
