Project description:The goal of this experiment was to identify the downstream targets of the GOLVEN6 peptide signaling pathway in Arabidopsis thaliana, specifically during lateral root initiation. Using an estradiol inducible GLV6 overexpression construct in wildtype and rgi1rgi5 double mutant (mutant in receptors for the GLV6 peptide) backgrounds, in combination with gravistimulation induced lateral root formation, the RGI receptor dependent transcriptional effects of GLV6 overexpression were characterized. An estradiol inducible GLV6 overexpression line in a wildtype (iGLV6) and in an rgi1rgi5 double receptor mutant background (rgi1rgi5/iGLV6) were used. 4-day old seedlings of both lines were gravistimulated (vertically grown seedlings were turned counterclockwise by 90°) to induce lateral root initiation in the resulting root bends. 8h after gravistimulation, seedlings of both lines were treated with 2µM of estradiol to induce GLV6 overexpression, or DMSO as a mock treatment. 3h and 6h after treatment, root bends were dissected and collected for RNA-sequencing. This yielded a total of 8 samples per replicate; 3h mock treated iGLV6 (IM3), 3h estradiol treated iGLV6 (IE3), 3h mock treated rgi1rgi5/iGLV6 (RM3), 3h estradiol treated rgi1rgi5/iGLV6 (RE3), 6h mock treated iGLV6 (IM6), 6h estradiol treated iGLV6 (IE6), 6h mock treated rgi1rgi5/iGLV6 (RM6), 6h estradiol treated rgi1rgi5/iGLV6 (RE6). For each sample, 4 replicates were obtained. This setup enabled the comparison of the GLV6 induced transcriptional effects between wildtype and rgi1rgi5 mutants at 2 time points after treatment, in samples that are strongly enriched for lateral root initiation events.

Project description:The expresion of dominant negative version of Arabidopsis TFIIS (TFIISmut) in plants lacking funtional TFIIS leads to severe growth defects. The genome-wide analysis of transcriptomic changes upon TFIISmut expression was performed by RNA-seq to better understand the biological importance of TFIIS. 10DAS seedlings of transgenic lines carring inducible GFP-TFIIS or GFP-TFIISmut transgenes were studied by RNA-seq following plants exposure to 24h b-estradiol or EtOH (mock) induction.
