Other claims from this paper (9)

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.

Other claims from this paper (12)

Intervention effect Four inhibitors decreased the endosperm glucose-to-maltose ratio after 10 days.
Intervention effect Three inhibitors reduced endosperm starch degradation.
Intervention effect Three inhibitors reduced seedling growth.
Intervention effect The fourth inhibitor did not affect starch degradation or seedling growth.
Mechanism Amylase inhibition apparently did not explain reduced starch degradation.
Mechanism Inhibitors acted directly on roots and coleoptiles to inhibit seedling growth.
Mechanism Seedling growth inhibition may reflect glycoprotein-processing glucosidase inhibition.
Intervention effect RNA interference lines had α-glucosidase activity reduced by up to 50%.
Intervention effect RNA interference lines did not change starch degradation or seedling growth.
Mechanism HvAGL97 was inferred to be the major endosperm maltose-to-glucose enzyme.
Mechanism HvAGL97 was inferred unnecessary for starch degradation.
Mechanism The inhibitor results imply other unidentified glucosidases are needed for endosperm starch degradation.

Overexpression of MIZU-KUSSEI1 Enhances the Root Hydrotropic Response by Retaining Cell Viability Under Hydrostimulated Conditions in Arabidopsis thaliana

Yutaka Miyazawa; Teppei Moriwaki; Mayumi Uchida; et al. Plant and Cell Physiology 2012. doi:10.1093/pcp/pcs129

Other claims from this paper (7)

Intervention effect MIZ1 overexpressors had a remarkably enhanced root hydrotropic response.
Intervention effect A greater number of MIZ1OE root cells remained viable under hydrostimulated conditions than in the wild type.
Mechanism The decrease in gravitropic response was not attributable to the enhanced hydrotropic response.
Intervention effect The miz2 mutation nullified the enhanced hydrotropic response in MIZ1OEs.
Intervention effect The auxin response inhibitor nullified the enhanced hydrotropic response in MIZ1OEs.
Intervention effect Expression of MIZ1 did not alter the expression of typical genes involved in drought tolerance.
Mechanism The authors suggest MIZ1 positively regulates hydrotropism at an early stage.

Intervention effect myr1 myr2 mutants had increased petiole length, leaf angle and apical dominance.
Mechanism All aspects of the myr1 myr2 phenotype required GA biosynthesis.
Mechanism The early-flowering phenotype of myr1 myr2 required FLOWERING LOCUS T.
Mechanism myr1 myr2 mutants showed an epistatic interaction with the phyB-9 mutant.
Intervention effect Over-expression of MYR1 or MYR2 produced GA-deficiency symptoms.
Intervention effect Application of gibberellic acid (GA3) rescued the GA-deficiency symptoms of MYR over-expression.
Association Loss of MYR1 and MYR2 function was associated with a twofold increase in GA20ox2 expression.
Association Loss of MYR1 and MYR2 function was associated with a 30% increase in GA4 levels.
Association Over-expression of MYR2 was associated with a 50% decrease in GA4 levels.
Mechanism MYR1 and MYR2 repress flowering and organ elongation, at least partly through a negative effect on bioactive GA levels.
