(Submitter supplied) Analysis of the abh1 mutant Arabidopsis plants following treatment with 50 uM abscisic acid (ABA). ABH1 encodes the large (80kDa) subunit of the nuclear mRNA cap binding complex and affects early ABA signal transduction events (Hugouvieux et al., 2001, Cell 106, 477). Keywords: stress response

Analysis of abh1 mutants treated with abscisic acid (ABA). ABH1 encodes a nuclear mRNA cap-binding protein homolog. The abh1 mutant is hypersensitive to ABA, a plant hormone that regulates development and abiotic stress responses. Results provide insight into the role of ABH1 in ABA signaling.

(Submitter supplied) The processing of Arabidopsis thaliana microRNAs (miRNAs) from longer primary transcripts (pri-miRNAs) requires the activity of several proteins, including DICER-LIKE1 (DCL1), the double stranded RNA binding protein HYPONASTIC LEAVES1 (HYL1), and the zinc finger protein SERRATE (SE). It has been noted before that the morphological appearance of weak se mutants is reminiscent of plants with mutations in ABH1/CBP80 and CBP20, which encode the two subunits of the nuclear cap-binding complex. 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) Whole genome small RNA sequencing (wild-type Col-0, abh1-1, ein5-6, ein5-6 abh1-1) and 5'-RACE (GMUCT) (wild-type Col-0 and ein5-6) sequencing of parenthetically indicated genotypes of Arabidopsis using the Illumina Genetic Analyzer. Whole-genome oligonucleotide tiling microarrays were used for gene expression studies of the entire transcriptome for wildtype Col-0, abh1-1, ein5-6, and ein5-6 abh1-1 plants. more...

(Submitter supplied) In this study, we have identified genes that are respectively activated and repressed by the low concentration of ABA and show that ROP10 gates a specific subset of genes that are responsive only to a low ABA concentration.

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) The development of high-throughput genomic technologies has revealed that a large fraction of the genomes of eukaryotes is associated with the expression of noncoding RNAs. One class of noncoding RNA, the cis-natural antisense transcripts (cis-NATs), are particularly interesting as they are at least partially complementary to the protein-coding mRNAs. Although most studies described cis-NATs involved in the regulation of transcription, a few reports have shown recently that cis-NATs can also regulate translation of the cognate sense coding genes in plants and mammals. more...

(Submitter supplied) Adaptive response to stress involves an extensive reprogramming of gene expression. Under stressful conditions, the induction of efficient changes in mRNA production is crucial for maximized plant survival. Transcription and pre-mRNA processing are two closely related steps in mRNA biogenesis, yet how they are controlled in plant stress response remains elusive. Here, we show that the Arabidopsis nuclear cap-binding complex (CBC) component CBP20 directly interacts with ELF7, a subunit of the transcription elongation factor RNA Pol II-associated factor 1 complex (PAF1c) to promote RNA Pol II transcription in plant response to salt stress. more...
