Figure 5: Transcriptional response to NatA depletion.
From: Downregulation of N-terminal acetylation triggers ABA-mediated drought responses in Arabidopsis
ABA steady-state levels and transcription of ABA-related genes were determined in leaves of 6-week-old wild type and NatA depleted grown on soil with regular water supply. (a) Transcript steady-state level of the ABA-inducible marker gene, LEA7. (N=3) (b) Steady-state levels of ABA. (N=5) (a,b) Data are represented as mean±s.e. Asterisks indicate significant differences to wild type. (P<0.05, Student’s t-test). (c,d) Venn diagrams for comparison of downregulated (c) and upregulated genes (d) in wild-type plants by drought stress (10 days) with genes that are regulated in NatA-depleted plants under control conditions when compared with wild type. Global transcriptional response in leaves of well-watered amiNaa10 (green), amiNaa15 (blue) was compared with non-stressed wild-type plants (control) as determined by hybridization of total mRNA to the Gene 1.0 ST Array (Affymetrix, Germany). (N=4).
