Phenotype
abscisic acid resistant, reduced sensitivity to ABA inhibition of germination, germinates in the presence of 5 microM ABA; dormancy response appears to be as expected for abi4; reduced sensitivity to the inhibitory effects of sugars on early seedling development, germinates and forms seedlings with expanded cotyledons and true leaves on concentrations of glucose (0.3 M), sucrose (0.3 M), mannose (2mM) or sorbitol (0.4 M) that inhibit these processes in wt plants; decreased sensitivity to the presence of the GA biosynthesis inhibitor paclobutrazol (35 mg/L ); does not exhibit compromised water relations, not wilty; lacks trichomes on stems and leaves, some trichomes in leaf margins; same as sis5-4.
