(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) Salicylic acid (SA) levels increase in Arabidopsis upon exposure to low temperature for more than a week. This cold-induced SA biosynthesis was found to proceed through the isochorismate synthase (ICS) pathway. The sid2-1 mutant is deficient in ICS1 and does not make SA at low temperature. We used microarray analysis to examine the genes differentially regulated by low temperature that were dependent on SA

(Submitter supplied) CAMTA3 is known to be involved in regulation of induction of early cold-responsive genes, CBF1 and CBF2 at cold conditions and of suppression of SA production at warm temperature. Considering a functional redundancy of CAMTA family members in both warm and cold conditions, high-order of camta mutants, camta double and triple mutants, were generated and used to determined the effects of their regulation using microarray analysis.

(Submitter supplied) Water availability is the biggest single limitation on plant productivity worldwide. In Arabidopsis, adjustments to drought stress, involving changes in metabolism and gene expression drive increased drought tolerance and initiate diverse drought avoidance and escape responses. To address regulatory processes that integrate these complex responses we hypothesised that we needed to identify genes that govern early responses to drought. more...

(Submitter supplied) We sequenced mRNA of WT, p35S:AtBBD1 (OX) and atbbd1 (KO) plants. Plants were grown in soil for three weeks at 23 ℃ with 60% relative humidity. mRNA was isolated 6 hours after threating with 20% PEG.

(Submitter supplied) In order to study the improtance of HSFA6b in salt and heat stresses of arabidopsis, we generated the HSFA6b-overexpression (HSFA6b-OE) and dominant-negative (HSFA6b-RD) mutant lines. We used microarray to investigate how genes regulated by HSFA6b after NaCl or heat shock treatment.

(Submitter supplied) In view of the continuous salinization of arable lands world-wide, there is an urgent need to better understand the mechanisms underlying plant responses to salt stress at different stages of their development. We investigated the role of calmodulin (CaM)-binding transcription activator 6 (CAMTA6) under salinity stress during early germination in Arabidopsis. These analyses suggest that ABA signaling is involved in CAMTA6-dependent salt-responsive gene expression, consistent with the ABA hyper-tolerance phenotype and the lack of HKT1 response to ABA and NaCl in the camta6 mutants.

(Submitter supplied) Plants adapt to abiotic and biotic stresses by activating abscisic acid-mediated (ABA) abiotic stress-responsive and salicylic acid-(SA) or jasmonic acid-mediated (JA) biotic stress-responsive pathways, respectively. Although the abiotic stress-responsive pathway interacts antagonistically with the biotic stress-responsive pathways, the mechanisms that regulate these pathways remain largely unknown. 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) AtERF#111/ABR1 belongs to the group X of the ERF/AP2 transcription factor family (GXERFs) and is shoot specifically induced under submergence and hypoxia. It was described to be an ABA-response repressor, but our data hint at a completely different function. Here we present evidence that AtERF#111 is involved in the wounding response. Expression profiling of ERF#111-overexpressing (OE) plants demonstrates that AtERF#111 is a transcriptional activator of wounding response genes. more...

(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...
