Expression data from Arabidopsis thaliana under phosphate starvation stress

Project description:We performed a transcriptomic analysis of Pi starvation responses in Arabidopsis thaliana (Columbia-0) wild type plants under phosphate starvation stress and in plants with altered PHR1(-like) activity, comparing mutants of phr1 and phr1-phl1 grown in phosphate-lacking medium. Results show the central role of PHR1 and functionally redundant members of its family in the control of transcriptional responses to Pi starvation. The analysis was performed in wild-type plants grown for seven days in complete (+Pi) and Pi-lacking (-Pi) Johnson solid media and the single phr1 and double phr1-phl1 mutants grown for 7 days in –Pi medium. Three independent biological samples of total RNA from shoot and root were hybridized separately.

Expression data from Arabidopsis thaliana PHR1 primary targets genes under phosphate starvation stress

Project description:We performed a transcriptomic analysis of Pi starvation responses in Arabidopsis thaliana (Columbia-0) phr1 mutant plants expressing PHR1 in presence of cicloheximide, that inhibit protein translation, thus preventing any effect of PHR1 on the expression of indirect targets. Results show the primary target genes of PHR1 in the responses to Pi starvation. The analysis was performed in phr1 plants and phr1 plants overexpressing a fusion GR:PHR1 (OXGR:PHR1) whose activity is postranslationally controlled by dexamethasone (DEX), that allows studying gene expression upon PHR1 activation and the concomitant inhibition of translation with cycloheximide (CHX), thus preventing any effect of PHR1 on the expression of indirect targets. To perform this study, phr1 and OXGR:PHR1 phr1 plants were grown for seven days in complete Johnson liquid media (+Pi), 2 days in Pi-lacking media (-Pi) and then supplemented with 5 µM DEX and 10 µM CHX for 6 hours before harvesting. Three independent biological samples of total RNA from shoot and root were hybridized separately.

RNA-seq of Arabidopsis thaliana seedlings treated with MeJA or flg22 under full and low phosphate conditions

Project description:This study evaluates the transcriptome of Arabidopsis thaliana seedlings chronically exposed to the hormone Methyl Jasmonate (MeJA) or to the bacterial elicitor flg22 (a 22-amino acid peptide from flagellin). Treatments were performed under high and low phosphate availability using wild-type Col-0 plants and the phr1 phl1 mutant.

Transcriptional profiling of Arabidopsis thaliana grown under arsenate stress

Project description:We examined the changes in gene expression in Arabidopsis thaliana grown under arsenate stress. The transcriptional profiling reveals antioxidant activity and repression of the phosphate starvation response. Keywords: dual label, stress response This experiment included a comparison of three biological replicate controls against three biological arsenate-stressed replicates with a dye-swap technical replicate for a total of six microarray slide hybridizations.
