Project description:Liquid grown, seven day old wild type Arabidopsis seedlings and seedlings carrying a cDNA encoding the ABA INSENSITIVE GROWTH 1 (ABIG1) gene under the control of an estrogen inducible promoter were treated with estrogen for 0, 60 and 120 minutes at which point seedlings were flash frozen and mRNA was extracted.
Project description:To identify targets of the C2H2 zinc finger protein ZINC 34 FINGER OF ARABIDOPSIS THALIANA 14 (ZAT14, AT5G03510), we used an estradiol-inducible system for inducible expression of ZAT14, comparing gene expression in estradiol-treated plants and mock-treated 5-day old seedlings 8 hours after estradiol or mock treatment.
Project description:Transcriptional profiling of Arabidopsis wild-type (Col0) control seedlings with corresponding mutant seedlings is performed using Aligent's Whole Arabidopsis Gene Expression Microarray (G2519F, V4, 4x44K).
Project description:Retrograde signals emanate from the DNA-containing cell organelles (plastids and mitochondria) and control the expression of a large number of nuclear genes in response to environmental and developmental cues. Previous studies on retrograde signaling mainly analyzed the regulation of nuclear gene expression at the transcriptional level. To determine the contribution of post-transcriptional regulation to plastid retrograde signaling, we combined label-free proteomics with transcriptomic analysis of Arabidopsis thaliana seedlings and studied the response in whichto interference with the plastid gene expression (PGE) pathway of retrograde signaling.
