(Submitter supplied) The functions of AP2/ERF family transcription factors in stress responses are well documented, but their roles in the brassinosteroid (BR)-regulated growth and stress responses have not been established. Here we show that stress-inducible AP2/ERF family transcription factor TINY inhibits BR-regulated growth while promoting drought response. TINY overexpression plants have stunted growth, increased sensitivity to BR biosynthesis inhibitors and compromised BR-responsive gene expression. more...

(Submitter supplied) To find genes directly regulated by ORA47, the P35S:ORA47-GR transgenic line was grown in the normal condition, treated with DEX and as well cycloheximide (CYC), prevented secondary transcriptional regulation downstream of ORA47 regulation by blocking protein synthesis. Gene expression patterns were then analyzed by microarray.

(Submitter supplied) CDK8 is a key subunit of Mediator complex, a large multiprotein complex that is a fundamental part of the conserved eukaryotic transcriptional machinery. However, the biological functions of CDK8 in plant abiotic stress responses remain largely unexplored. Here, we demonstrated CDK8 as a critical regulator in the abscisic acid (ABA) signaling and drought response pathways in Arabidopsis. Compared to wild-type, cdk8 mutants showed reduced sensitivity to ABA, impaired stomatal apertures and hypersensitivity to drought stress. more...

(Submitter supplied) Based on the distinct phenotypes of BEH2-overexpressing plants, we compared the functional roles of BZR1 and BEH2. The BEH2 is a stronger transcriptional regulator of BR-responsive gene expression than BZR1. It appears that BEH2 also regulates gene expression in a BR-independent manner.

(Submitter supplied) The CAMTA1 mutant and Col-0 were studied under water and drought condition. The camta1 showed stunted primary root growth under osmotic stress. The expression analysis revealed drought recovery as major indicative pathway along with membrane and chloroplast related protein in camta1 under drought stress. Large number of positively regulated genes were related to osmotic balance, transporters, AP2 and ABA. more...

(Submitter supplied) To study the transcriptional changes in waterlogging stress 30 day old Arabidopsis plants were subjected to 4 days of waterlogging stress. We have employed whole genome microarray expression profiling as a discovery platform to identify genes that behave diferentially to the stress. The information could be used to generate transgenic lines that are resistant to waterlogging stress and can be applied to other closely related species to compromise the crop yeild loss. more...

(Submitter supplied) Considering global climate changes, incidences of combined drought and heat stress are likely to increase in the future and will considerably influence plant-pathogen interactions. Until now, little is known about plants exposed to simultaneously occurring abiotic and biotic stresses. To shed some light on molecular plant responses to multiple stress factors, a versatile multi-factorial test system, allowing simultaneous application of heat, drought and virus stress, was developed. more...

(Submitter supplied) We utilized RNA-seq to identify transcriptome changes following knockdown of the Arabidopsis N-terminal acetyltransferase NAA50. Transgenic Arabidopsis plants carrying a dexamethasone-inducible amiRNA were used to study the effects of NAA50 knockdown. Significant changes occurred in the transcriptomes of NAA50 knockdown plants at 12 and 24 hours after dexamethasone treatment. These changes demonstrate that loss of NAA50 results in a reduction in signaling related to plant growth and development, as well as an increase in the expression of stress- and defense-related pathways.
