(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) Plant homeodomain (PHD) finger proteins affect growth and development by regulating transcription and reading epigenetic modifications of histones, but their functions in abiotic stress responses remain largely unclear. Here we characterize seven Arabidopsis thaliana Alfin1-like PHD finger proteins (ALs) in the response to abiotic stresses. ALs localize to the nucleus and repress transcription. Except AL6, all the ALs bind to G-box element. 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) Arabidopsis ABA hpersensitive germination2-1 mutant shows an enhanced sensitivity to ABA. This mutant has higher levels of endogenous ABA. This mutant also exhibited SA hypersensitivity and dwarf phenotype. Regarding SA hypersensitivity, ahg2-1 exhibits higher endogenous SA level and an enhanced resistance to pathogenic bacteria. Since AHG2 encodes the Arabidopsis polyA specific ribonuclease that is involved in mRNA degradation, presumably abnormal accumulation of some mRNAs confers the unique phenotype. more...

(Submitter supplied) In plants, endogenous and environmental signals such as light control the timing of the transition to flowering . Two phytochrome B-interacting transcription factors, VASCULAR PLANT ONE–ZINC FINGER1 (VOZ1) and VOZ2 redundantly promote flowering in Arabidopsis thaliana. In the voz1 voz2 mutant the expression of FLOWERING LOCUS C (FLC) was up-regulated and expression of FLOWERING LOCUS T (FT) was down-regulated, which was proposed to be the cause of late flowering in voz1 voz2. more...

(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) Cold stress is one of the most severe environmental conditions which cause huge losses in crop production worldwide. We identified a DEAD box RNA helicase, RCF1 (Regulator of CBF gene expression 1) that controls pre-mRNA splicing of cold-stress-responsive genes including positive and negative regulators of CBF genes. We used whole genome tiling array analysis under cold stress to identify transcripts which are mis-spliced/intron-retained in rcf1-1.

We identified a DEAD box RNA helicase, RCF1 (Regulator of CBF gene expression 1) that controls pre-mRNA splicing of cold-stress-responsive genes including positive and negative regulators of CBF genes.

(Submitter supplied) Leaf growth is a complex developmental process that is continuously fine-tuned by the environment. Various abiotic stresses, including mild drought stress, have been shown to inhibit leaf growth in Arabidopsis thaliana (Arabidopsis), but the underlying mechanisms remain largely unknown. Here we identify the redundant Arabidopsis transcription factors ETHYLENE RESPONSE FACTOR 5 (ERF5) and ERF6 as master regulators which adapt leaf growth to environmental changes. more...

(Submitter supplied) To identify chloroplastic H2O2-responseive genes, an estrogen-inducible RNAi method was used for silencing of tAPX, a H2O2-scavenging enzyme in chloroplasts. At 48 h after treatment with estrogen, the expression of tAPX was silenced in the IS-tAPX-19-23 plants, but not in the IS-GUS-2-17 plants (negative control), resulting a large change in gene expression. These genes are candidates for chloroplastic H2O2-responseive genes.
