Blue-light-induced PIN3 polarization for root negative phototropic response in Arabidopsis.

It is reported that the auxin efflux carrier PIN-FORMED (PIN) 3 is involved in asymmetric auxin distribution and root negative phototropism.

Glucose inhibits root meristem growth via ABA INSENSITIVE 5, which represses PIN1 accumulation and auxin activity in Arabidopsis.

The data suggest that ABI5 functions in the glucose-mediated inhibition of the root meristem zone by repressing PIN1 accumulation, thus leading to reduced auxin levels in roots.

Proper PIN1 Distribution Is Needed for Root Negative Phototropism in Arabidopsis

It is shown that the auxin efflux carrier PIN-FORMED (PIN) 1 is involved in asymmetric auxin distribution and root negative phototropism.

WRKY13 Enhances Cadmium Tolerance by Promoting D-CYSTEINE DESULFHYDRASE and Hydrogen Sulfide Production1

It is reported that DCD-mediated H2S production enhances plant Cd tolerance in Arabidopsis (Arabidopsis thaliana), and the expression of DCD was stimulated by Cd stress, and this up-regulation was mediated by a Cd-induced transcription factor, WRKY13, which bound to the DCD promoter.

A gain-of-function mutation in IAA8 alters Arabidopsis floral organ development by change of jasmonic acid level

Results indicated that in IAA8::GFP-mIAA8 plants, JA biosynthetic genes including DAD1, AOS, and ORP3 were dramatically down-regulated and JA level in the flowers was reduced to 70 % of that in wild-type.

The COP1 Target SHI-RELATED SEQUENCE5 Directly Activates Photomorphogenesis-Promoting Genes

These results demonstrate that SRS5 directly activates the expression of downstream genes HY5, BBX21, and BBX22 and is a target of COP1-mediated degradation in Arabidopsis, and indicates that S RS5 is a positive regulator of photomorphogenesis.

Auxin abolishes SHI-RELATED SEQUENCE5-mediated inhibition of lateral root development in Arabidopsis.

The data reveal that SRS5 negatively regulates LR formation by repressing the expression of LBD16 and LBD29 and that auxin releases this inhibitory effect through ARF7 and ARF19.

[Activation of hippocampal D1 dopamine receptor inhibits glutamate-mediated depression induced by chronic unpredictable mild stress in rats].

The results suggest that agonists of D1 dopamine receptor could reduce the concentration of glutamic acid in hippocampus, and its antidepressant effect may be mediated by AMPA receptor partially.
