(Submitter supplied) Transcriptional reprogramming plays a key role in drought stress responses, preceding the onset of morphological and physiological adaptations. The best characterised signal regulating gene expression in response to drought is the phytohormone abscisic acid (ABA). ABA-regulated gene expression, biosynthesis and signalling are highly organised in a diurnal cycle, so that ABA-regulated physiological traits occur at the appropriate time of the day. 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) 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) The ubiquitin 26S proteasome system (UPS) selectively degrades cellular proteins, which results in physiological changes to eukaryotic cells. F-box proteins are substrate adaptors acting within the UPS and are responsible for the diversity of potential protein targets. Plant genomes are enriched in F-box genes, but the vast majority of these have unknown roles. This work investigated the Arabidopsis F-box gene F-BOX STRESS INDUCED 1 (FBS1) by identifying differentially expressed genes between wild type (No-0) and an fbs1 insertion line. more...

(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) ATH1 GeneChip was used for gene expression analysis of wild-type plants and dor mutant under drought treatment (both the wild-type and dor plants were grown under normal watering conditions for 24 days and then stressed by completely depriving of irrigation for 10 days). Two biological repeat experiments were conducted and the raw data was analyzed applying Affymetrix GCOS software. Keywords: both the wild-type and dor plants were grown under normal watering conditions for 24 days and then stressed for 10 days

(Submitter supplied) N-terminal protein acetylation is one of the most common protein modifications in eucaryotes and is catalyzed co-translationally by N-terminal aceytltransferases (Nats). Regarding the number of predictaed substrates, NatA is the main Nat complex in human and yeast and is composed of the catalytic subunit NAA10 and the auxilliary subunit NAA15. The down-regulation of NAA10 and NAA15 results in Arabidopsis in drought resistant plants. more...
