Effect of blocking ABA-signaling in different tissues on transcriptomic changes induced by ABA-treatment

Project description:ABA-signaling in disitinct root tissues is important for xylem phenotypes observed both under mock and ABA-treatment. We performed RNA-sequencing on Arabidopsis plants in which ABA-signalling is specifically blocked in the endodermis (J0571), the xylem (J1721) or the procambium (Q0990) to investigate the underlying transcriptomic changes.

Transcriptomic changes upon ABA treatment dependent on VND transcription factors

Project description:Distinct transcriptomic changes upon ABA treatment are dependent on different VND transcription factors. We performed RNA-sequencing on mock and ABA-treated Arabidopsis plants to investigate the impact of VND1/2/3 and VND7 on gene expression changes upon ABA treatment.

Gene expression profiling of retrograde PAP-signaling and ABA-signaling mutants in response to ABA treatment

Project description:Chloroplast-nuclear retrograde signaling is viewed as a mechanism for inter-organelle communication. Here we show the SAL1-PAP (3′-phosphoadenosine 5′- phosphate) retrograde pathway functions more broadly in guard cells, interacting with abscisic acid (ABA) signaling at least in part via exoribonucleases. Unexpectedly, PAP bypasses the canonical signaling components ABA Insensitive 1 (ABI1) and Open Stomata 1 (OST1) by priming an alternative pathway that restores ABA-responsive gene expression, ROS bursts, ion channel function and stomatal closure in ost1-2. This alternative pathway up-regulates lowly expressed Calcium Dependent Protein Kinases (CDPKs) which have the capacity to activate the key slow anion channel SLAC1 in response to ABA-mediated and ost1-2 independent calcium release. The role of PAP in priming an alternative pathway to bypass components previously considered essential for stomatal closure demonstrates how a chloroplast signal can have broader roles as a secondary messenger to directly intersect with and tune hormone signaling.

CRK36 RNAi ABA treatment

Project description:Genome-wide expression studies by an Arabidopsis 3 Oligo Microarray (Agilent Technologies, Switzerland) were performed using wild-type and CRK36 RNAi transgenic plants growing on plate containing ABA. We collected young seedlings growing on the plate containing 0.5 ?M ABA for 10 days.

Sugarcane transcriptome - ABA treatment

Project description:Plants (genotype SP80-3280, CTC, Brazil) cultivated in axenic cultures were transferred to a growth chamber at 26°C on a 16 h/8 h light/dark cycle with a photon flux density of 70 µE.m-2.s-1 and cultivated for 4 weeks. After this period, the phytohormone ABA (Sigma Chem. Co) was added to the culture medium to a final concentration of a 100 µmol.L-1. Control plants were treated with distilled water. Leaves were collected 0 h, 30 min, 1 h, 6 h and 12 h after exposure to ABA and immediately frozen in liquid nitrogen. Six plantlets were used for each time point. Extraction of total RNA was performed separately on each sample pool. Keywords: time course of hormone treatment
