Project description:rs06-01_pld - pld - Role of PLDzeta to abiotic stress adaptation - A double mutant PLDzeta1,2 was obtained in a Columbia background. 12-day-old Arabidopsis seedlings, wt or double mutant, were treated with either NaCl (200 mM), mannitol (400 mM) or with 4degreeC temperature during 3 h. 3 biological replicates were pooled. Keywords: gene knock out,treated vs untreated comparison
Project description:Post-translational histone modifications and the dynamics of histone variant H2A.Z are key mechanisms underlying the floral transition. In yeast, SWR1-C and NuA4-C mediate the deposition of H2A.Z and the acetylation of histone H4, H2A and H2A.Z respectively. Yaf9 is a subunit shared by both chromatin remodeling complexes. The significance of the two Arabidopsis YAF9 homologs, YAF9A and YAF9B, is unknown. We performed a transcriptomic analysis of wild-type and yaf9a yaf9b double mutant seedlings in order to reveal target genes whose transcription is regulated by YAF9 proteins.
