CS22 — Mutant plants had increased ABA content in response to both, low water potential and exogenous ABA. Also, accumulation of proline was reduced 4-5 fold in mutant plants compared to WT, in response to low water potential, and exogenously applied ABA.
CS22 — Mutant showed a similar sensitivity to 25 mM trehalose as wild type (inhibition of root growth).
CS22 — abscisic acid resistant; reduced sensitivity to ABA inhibition of germination; germinates in the presence of 10 microM ABA; increased level of endogenous ABA during seed development; has compromised water relations; increased leaf transpiration rate which leads to symptoms of wilting and withering especially under low relative humidity and water stress; reduced seed dormancy, fresh seeds germinate at high frequency; decreased sensitivity to the presence of GA biosynthesis inhibitors such as paclobutrazol; reduced sensitivity to salt and osmotic stress during germination; reduced ABA-induced cytoplasmic calcium elevations in guard cells.
CS6520 — late flowering phenotype (delay in the transition to flowering is relatively stronger under long day than under short day light conditions), dark-green rosettes with increased number of leaves; very bright green stems and siliques, complete absence of lobed plates and tube-shaped structures on the epicuticular wax layer; dwarf (12-17 cm height), responsive to gibberellin, gibberellin not required for germination; abscisic acid resistant, reduced sensitivity to ABA inhibition of germination.
CS72323 — ABA hypersensitive
abi1-1 bps1-2 — Double mutants were indistinguishable from bps1 single mutants.
abi1td — mutant showed ABA-hypersensitive regulation of seed germination and root growth; increased sensitivity to salt and osmotic stress during germination; increased sensitivity to glucose during germination; reduced leaf transpiration rate; increased ABA-induced stomatal closure; stomatal responses to 0.5 mM H2O2 and Ca2+ as WT; WT sensitivity to GA, NAA and ACC; mutant plants had decreased ABA content in response to drought and ozone; increased ACC production in response to ozone.
ear1-1/abi1-2/abi2-2/hab1-1 — Germination inhibited, root growth arrested by ABA, tolerant to drought stress, ABA treatment resulted in lower PP2C and higher OST1 activity.
