Expression data from dark-grown AtGATA2 (At2g45050) overexpression transgenic line, homozygous bri1-116 and Col-0 wild type

Project description:Molecular genetic analyses support important roles for the AtGATA2 gene in brassinolide (BR) and light regulation of plant development. The overexpression line 6-9 of AtGATA2 suppresses the etiolated phenotype of Col-0 grown in the dark. Using microarray analysis, we identified genes differentially expressed in the AtGATA2ox transgenic line 6-9 compared to wild type, and genes differentially expressed in the AtGATA2ox transgenic line 6-9 compared to the bri1-116 single mutant. Consistent with the phenotypic similarity of bri1-116 and AtGATA2, overall about 93% of the co-regulated genes were affected in the same way by GATA2-ox and bri1-116.

Expression data from dark-grown BR double mutant bzr1-1D;bri1-116, single mutant bri1-116, and wildtype

Project description:Molecular genetic analyses support a central role of BZR1 in Brassinosteroid (BR) regulation of plant development. The dominant bzr1-1D mutation, which stabilizes the BZR1 protein, completely suppresses the de-etiolated phenotype of the null bri1-116 mutant grown in the dark. Using microarray analysis, we identified genes differentially expressed in bri1-116 compared to wild type and genes differentially expressed in the bzr1-1D;bri1-116 double mutant compared to the bri1-116 single mutant. Consistent with the phenotypic suppression of bri1-116 by bzr1-1D, about 80% of the genes affected in bri1-116 were affected oppositely by bzr1-1D BZR1 regulated genes were generated from comparing genes differentially expressed by bzr1-1D;bri1-116 and bri1-116. Genes affected by BRI1 were generated from comparing differentially expressed genes of bri1-116 and Col control. ANOVA was used to find genes whose expression was different between bzr1-1D;bri1-116 and bri1-116 or between bri1-116 and Col samples [see Supplementary file below].

Spatiotemporal brassinosteroid signaling and antagonism with auxin control Arabidopsis root growth.

Project description:Analysis of brassinosteroid (BR) and auxin effects on gene expression in Arabidopsis roots. Our genomic results indicate that BR and auxin induce largely opposite gene expression responses in primary roots. RNA-Seq for 7-day-old Arabidopsis Col-0, dwf4, bri1-116, and bri1-116;bzr1-1D roots grown on regular medium and treated with brassinolide, auxin or mock solution for 4 hr.

Effect of AAF overexpression on the leaves before bolting

Project description:Analysis of leaves from 3-week old transgenic plants overexpressing AAF, which is a senescence-associated gene. Overexpression of AAF promoted leaf senescence and accumulation of reactive oxygen species (ROS) in transgenic plants. Results provide insight in the role of AAF in ROS homeostasis and the function in leaf senescence. 3-week-old plants of Col-0 (wild type, as control) and AAF-OX (overexpression line) were grown in long day condition (16hr light/8hr dark). Rosette leaves of Col-0 and AAF-OX were used for total RNA extraction and cDNA synthesis. cDNA labeling, array hybridization, and scanning followed standard Affymetrix expression array protocol. Two independent sets of microarray analyses were performed in this study.

Chaperone-like protein DAY plays critical roles in photomorphogenesis

Project description:We found that the transcriptome of day RNAi seedlings significantly overlaps with that of the bri1-116 mutant, especially in the dark. These data indicate that DAY acts as a positive regulator of BR signaling.

Impact of RAP2.12 alterations on gene expression in hypoxic and aerobic conditions in Arabidopsis thaliana

Project description:In this study we analyzed the effect of overexpression of an HA-tagged version of the ERF RAP2.12 on the transcriptome levels in aerobic and hypoxic-treated (O2 21% and 1%, respectively) Arabidopsis thaliana rosettes. We also analyzed the effect of a RAP2.12 and RAP2.2 simultaneous silencing in aerobic and hypoxic-treated (O2 21% and 1%, respectively) Arabidopsis thaliana rosettes. We treated Arabidopsis Col-0 (wt) rosettes and transgenic HA::RAP2.12 and amiRAP2.2-12 , 5-week old, grown in 8/16 light/dark photoperiod with: -Control (22°C, dark, 21% O2, 1.5h). -Hypoxia (22°C, dark, 1% O2, 1.5h).
