CHD3 proteins and polycomb group proteins antagonistically determine cell identity in Arabidopsis.

Aichinger Ernst E Villar Corina B R CB Farrona Sara S Reyes José C JC Hennig Lars L Köhler Claudia C

PLoS genetics 20090814 8

Dynamic regulation of chromatin structure is of fundamental importance for modulating genomic activities in higher eukaryotes. The opposing activities of Polycomb group (PcG) and trithorax group (trxG) proteins are part of a chromatin-based cellular memory system ensuring the correct expression of specific transcriptional programs at defined developmental stages. The default silencing activity of PcG proteins is counteracted by trxG proteins that activate PcG target genes and prevent PcG mediate ...[more]

Transcription profiling of Arabidopsis srk2cf mutant plants under drought stress for 0, 1 and 4 hours

Project description:Microarray experiments were performed using Arabidopsis wild type plants (Col-0) and srk2cf double knockout mutants to investigate functions of two osmotic stress-activated protein kinases, SRK2C and SRK2F. Transcription profiles of wild type and mutants were compared under drought stress for 0, 1 and 4 h.

Genome wide analysis of glucose brassinosteroid interaction in Arabidopsis

Project description:Arabidopsis thaliana seeds after imbibition were inoculated in ½ MS medium supplemented with 0.8% agar and 1% sucrose. Once the plant material was uniformly germinated, the experimental conditions were applied. 5d old light-grown uniformly germinated seedlings were washed seven times with sterile water with last wash given by ½ MS liquid medium without sucrose to remove residual exogenous sugar and the plant material was kept in ½ MS liquid without sucrose in the dark for all subsequent steps. Cultures were shaken at 140 rpm at 22oC for 24 h and then 3 h treatment was given with liquid ½ MS without glucose and liquid ½ MS supplemented with BR (0.1 ?M EBR), glucose (3%), glucose (3%) + BR (0.1 ?M EBR). Seedlings were harvested after 3h and preceded for RNA isolation and Microarray analysis.

Transcriptional profiling by array of Arabidopsis ABA auxotroph to identify early downstream targets of transcription in response to a small dose of abscisic acid (ABA)

Project description:Abscisic acid (ABA) is a plant hormone that is important in responding to various environmental stresses. Using an ABA auxotroph in Arabidopsis (aba2-2) as the plant material, we would like to identify early downstream targets of transcription in response to a small dose of ABA, 1 uM. We also added cycloheximide to preferentially obtain immediate targets of ABA addition. We believe that using a sensitized background of an ABA auxotroph would yield a set of genes that are very closely regulated by ABA at the transcriptional level. This data set will be used for network analysis of ABA signaling.
