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 sis5-3.
