Project description:To identify putative regulatory elements enriched in the promoters of target genes of the PGE-dependent retrograde signaling pathway, we analyzed 500 bp regions of sequence upstream of genes whose expression was down-regulated by lincomycin. We treated dark-grown Arabidopsis seedlings with lincomycin, sampled them before or after a short illumination and examined the genomic response using Affymetrix ATH1 oligonucleotide microarrays. Differentially regulated genes were ranked based on descending degree of significance (p-value) and the top 50 genes affected by lincomycin in dark grown seedlings and top 50 genes affected by the antibiotic after illumination were selected for further analysis. Experiment Overall Design: 2*2 factorial design, two variables are (1) with/without lincomycin treatment (2) with/without red illumination. There are 2 replicates for each condition.

Project description:The role of abscisic acid (ABA) signalling in the ascorbic acid (AA)-dependent control of plant growth and defence was determined using the vtc1 and vtc2 mutants, which have impaired ascorbic acid synthesis, and in the abi4 mutant that is impaired in ABA-signalling. ABA levels were increase in the mutants relative to the wild type (Col0). Like vtc1 the vtc2 mutants have a slow growth relative to Col0. However, the wild type phenotype is restored in the abi4vtc2 double mutant. Similarly, the sugar sensing phenotype of in the abi4 is reversed in the abi4vtc2 double mutant. The vtc1 and vtc2 leaf transcriptomes show up to 70 % homology with abi4. Of the transcripts that are altered in the mutants a relative to Col0, only a small number are reversed in the abi4vtc2 double mutants relative to either abi4 or vtc2. We conclude that AA controls growth via an ABA and abi4-dependent signalling pathway. The vtc and abi4 mutants have enhanced glutathione levels and common redox signalling pathways leading to similar gene expression patterns.

Project description:The AP2/ERF domain transcription factor ABSCISIC ACID INSENSITIVE4 (ABI4) modulates diverse developmental and physiological processes by integrating multiple environmental factors and phytohormone signals in plants. To further investigate the molecular mechanism of ABI4 in plant development, we examined the global gene expression in the WT and abi4-1 plants using RNA sequencing.
