Beverly A. Underwood; Denise M. Tieman; Kenichi Shibuya; et al. PLANT PHYSIOLOGY 2005. doi:10.1104/pp.104.051144

Other claims from this paper (9)

Mechanism Ethylene regulates multiple components of floral VOC emission.
Observation PhBSMT1 and 2 mRNA expression declines temporally and spatially in floral organs.
Association Post-pollination VOC emission parallels reduced PhBSMT1 and 2 mRNA.
Association Under day/night cycles, rhythmic PhBSMT mRNA precedes methylbenzoate emission by about 6 h.
Intervention effect Constant darkness decreases PhBSMT mRNA and subsequent methylbenzoate emission.
Intervention effect Constant light increases PhBSMT mRNA and subsequent methylbenzoate emission.
Mechanism Light may influence cyclic methylbenzoate emission more strongly than the circadian clock.
Intervention effect PhBSMT RNAi flowers had minimal changes in other VOCs.
Mechanism The results implicate PhBSMT1 and 2 in methylbenzoate synthesis.

The AIP2 E3 ligase acts as a novel negative regulator of ABA signaling by promoting ABI3 degradation

Xiuren Zhang; Virginia Garreton; Nam-Hai Chua Genes & Development 2005. doi:10.1101/gad.1318705

Other claims from this paper (12)

Observation ABI3 is an unstable protein.
Observation AIP2, which contains a RING motif, can polyubiquitinate ABI3 in vitro.
Observation The AIP2 E3 ligase activity is abolished by mutations C230S and C231S in the RING motif.
Observation The AIP2 (C/S) mutant functions in a dominant-negative manner.
Observation AIP2 has a stronger binding affinity for the B2 + B3 domain of ABI3 than for the A1 + B1 domain.
Observation AIP2 ubiquitinates only the A1 + B1 domain of ABI3, not the B2 + B3 domain.
Intervention effect ABI3 levels are elevated upon induced expression of the AIP2 RING mutant.
Intervention effect The aip2-1-null mutant shows higher ABI3 protein levels than wild type after seed stratification.
Observation The aip2-1-null mutant is hypersensitive to ABA, mimicking the ABI3-overexpression phenotype.
Intervention effect AIP2-overexpression plants contain lower levels of ABI3 protein than wild type.
Intervention effect AIP2-overexpression plants are more resistant to ABA than wild type.
Mechanism The authors conclude that AIP2 negatively regulates ABA signaling by targeting ABI3 for post-translational destruction.
