Analysis of small GTPase rop10-1 knockout mutant seedlings following treatment with 1 uM abscisic acid (ABA). ROP10 is involved in the negative regulation of ABA responses. Results provide insight into the mechanisms underlying the regulation of the ROP10-mediated ABA signaling network.

(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) High salinity is one of the major environmental factors, which hampers plant growth, development and productivity. To better understand the regulatory mechanisms by which plants cope with salt stress, we used genetic approaches to identify salt hypersensitive mutant 9 (sahy9), a new allele of apum23, in Arabidopsis thaliana. The sahy9/apum23 mutant seedlings display postgemination developmental arrest and later become bleached under agar plates supplemented with various salt stressors. more...

(Submitter supplied) Soil salinity increasingly causes crop losses worldwide. Although roots are the primary targets of salt stress, the signaling networks that facilitate metabolic reprogramming to induce stress tolerance are less understood than those in leaves. Here, a combination of transcriptomic and metabolic approaches was performed in salt-treated Arabidopsis thaliana roots, which revealed that the group S1 basic leucine zipper transcription factors bZIP1 and bZIP53 reprogram primary C- and N-metabolism. more...

(Submitter supplied) Early rapid changes in response to the phytohormone abscisic acid (ABA) have been observed at the transcript level, but little is known how these transcript changes translate to changes in protein abundance under the same conditions. Here we have performed a global quantitative analysis of transcript and protein changes in Arabidopsis suspension cells in response to ABA using microarrays and quantitative proteomics. more...

(Submitter supplied) Growth daylength, ambient CO2 level, and intracellular hydrogen peroxide (H2O2) availability all impact plant function by modulating signalling pathways, but interactions between them remain unclear. Using a whole-genome transcriptomics approach, we exploited the conditional photorespiratory nature of the catalase-deficient cat2 mutant to identify gene expression patterns responding to these three factors. more...

(Submitter supplied) Abiotic stress is a major environmental factor that limits cotton growth and yield, moreover, this problem has become more and more serious recently and multiple stresses often occur simultaneously due to the global climate change and environmental pollution. We used microarrays to analyze the crosstalk of responsive genes to multiple abiotic stresses including ABA, cold, drought, salinity and alkalinity in cotton.

(Submitter supplied) Background: Over application of phosphate fertilizers in modern agriculture contaminates waterways and disrupts natural ecosystems. Nevertheless, this is a common practice among farmers, especially in developing countries as abundant fertilizers are believed to boost crop yields. The study of plant phosphate metabolism and its underlying genetic pathways is key to discovering methods of efficient fertilizer usage. more...

(Submitter supplied) To investigate differences in plant responses to salt and ABA stimulus, differences in gene expression in Arabidopsis in response to salt and ABA were compared using an Agilent oligo microarray. Four-week-old Arabidopsis thaliana ecotype Columbia (Col-0) seedlings were treated with either 150 mM NaCl or 10 μM ABA for 6 hours; unstressed seedlings (control sample) were collected in parallel to avoid the possible effects of circadian rhythms. more...

(Submitter supplied) Arabidopsis plants that have experienced stress from water withdrawal show an improved ability to tolerate subsequent exposures as a ‘memory’ from the previous stress. This physiological stress memory is associated with ‘transcriptional memory’ illustrated by a subset of dehydrations stress responding genes that produce significantly different transcript amounts during repeated dehydration stresses relative to their response in the first. more...

Background: The branching habit of plants is a key determinant of overall plant form and function with great relevance to modern agriculture. Shade signals transduced by phytochromes are major regulators of axillary bud outgrowth, and in turn control branching in both natural and agricultural environments. more...

(Submitter supplied) Knock out mutants of GPA1 (gpa1-5), GCR1 (gcr1-5) as well as their double mutant (gpa1-5 gcr1-5) were used to obtain genomewide transcriptome profile to deduce genomewide effect of both the subunits alone or in combination. Heterotrimeric G-protein signaling pathways have been implicated in a variety of biological processes in plants. While an impressive range of important plant responses are known to be mediated by G-protein signaling pathways, the genes that respond through these pathways are not yet known completely. more...

(Submitter supplied) The Arabidopsis thaliana mutant wrky33 is highly susceptible to the necrotrophic fungus Botrytis cinerea. Comparing the expression profiles of B. cinerea-infected wrky33 and WT plants we identified 2765 differentially expressed genes dependent on WRKY33, of which 1675 were up-regulated in the mutant (termed WRKY33-repressed genes) and 1090 were down-regulated in the mutant. Combined with ChIP-seq data 318 genes were identified as direct functional targets of WRKY33 at 14 h post inoculation with spores of Botrytis cinerea 2100.

(Submitter supplied) Green plants are more robust to hydrogen peroxide (H2O2) stress and contain high endogeneous H2O2 levels which is generated during photorespiration and photosynthesis. Therefore, exgeneous H2O2 application mostly impose oxidative stress. To reduce endogenous H2O2 background, we adopted a strategy which is to grow Arabidopsis seedlings in the dark to eliminate light-induced H2O2 production, thus to reduce the endogenous H2O2 level. more...

(Submitter supplied) Heterotrimeric G proteins mediate crucial and diverse signaling pathways in eukaryotes. To gain insights into the regulatory modes of the G protein and the co-regulatory modes of the G protein and the stress hormone abscisic acid (ABA), we generated and analyzed gene expression in G protein subunit single and double mutants of the model plant Arabidopsis thaliana. Through a Boolean modeling approach, our analysis reveals novel modes of heterotrimeric G protein action. more...
