Stress Induced Calcium Signaling Facilitates ABA Mediated Transcriptional Adaptation

Project description:ABA and calcium both function as central signals in developmental programs and environmental responses. Little is known about the way how both messengers functionally interact. Here we report that stress induced calcium signatures are essential and likely sufficient for inducing ABA accumulation in roots. Moreover, we show that calcium activated calcium sensor/kinase complexes directly phosphorylate and activate ABA responsive transcription factors. Our results reveal a molecular mechanism that allows for integrating, fine tuning and termination of hormonal and calcium signaling on the level of gene transcription.

Cytosolic calcium and nuclear calcium-regulated transcription networks in response to ABA and JA

Project description:Calcium acts as a universal second messenger to regulate gene expression in both developmental processes and responses to environmental stresses. Previous studies showed that a number of stimuli can induce calcium increases in the cytoplasm and nucleus, independently. However, the gene expression network deciphering [Ca2+]cyt and/or [Ca2+]nuc signaling pathway remain obscure. Using transgenic Arabidopsis containing a fusion protein, comprising rat parvalbumin (PV) with either a nuclear export sequence (PV-NES) or a nuclear localization sequence (NLS-PV), to selectively buffer the cytosolic or nucleosolic calcium, we identified the [Ca2+]cyt- or /and [Ca2+]nuc-regulated ABA- and MeJA-responsible genes with the Arabidopsis Genome Oligo array.

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.

RNA-seq analysis of ABA-treated Nicotiana benthamiana seedlings

Project description:Analysis of abscisic acid (ABA) perception and signaling in crops is complicated by the multigenic nature of the PYR/PYL/RCAR ABA receptor family and the reported functional redundancy, which is a formidable challenge, particularly in polyploid plants. Therefore, few molecular genetics studies have been performed in crop species to study the contribution of ABA signaling to balance plant growth and adaptation to the environment. Our data reveal ABA-responsive genes in Nicotiana benthamiana, an allotetraploid biotech crop, and provide a molecular framework for gene expression analyses aimed at optimizing plant growth and environmental adaptation in agriculture. To obtain the genome-wide transcriptional effect of ABA in Nb WT plants, we performed RNA-seq studies as described in experimental procedures. Differential gene expression analysis between mock- and ABA-treated seedlings was done with DESeq2 and genes with an absolute value of log2 fold change (log2FC) > 1 or (log2FC) < -1 and p-adjusted value (padj) < 0.05 were selected

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.

JAZ1 attenuates drought resistance by regulating JA and ABA signaling in rice

Project description:Jasmonates (JA) and abscisic acid (ABA) are phytohormones known to play important roles in plant response and adaptation to various abiotic stresses including salinity, drought, wounding, and cold. JAZ (JASMONATE ZIM-domain) proteins have been reported to play negative roles in JA signaling. However, direct evidence is still lacking that JAZ proteins regulate drought resistance. In this study, OsJAZ1 was investigated for its role in drought resistance in rice. Expression of OsJAZ1 was strongly responsive to JA treatment, and it was slightly responsive to ABA, salicylic acid, and abiotic stresses including drought, salinity, and cold. The OsJAZ1-overexpression rice plants were more sensitive to drought stress treatment than the wild-type rice Zhonghua 11 (ZH11) at both the seedling and reproductive stages, while the jaz1 T-DNA insertion mutant plants showed increased drought tolerance compared to the wild-type plants. The OsJAZ1-overexpression plants were hyposensitive to MeJA and ABA, whereas the jaz1 mutant plants were hypersensitive to MeJA and ABA. In addition, there were significant differences in shoot and root length between the OsJAZ1 transgenic and wild-type plants under the MeJA and ABA treatments. A subcellular localization assay indicated that OsJAZ1 was localized in both the nucleus and cytoplasm. Transcriptome profiling analysis by RNA-seq revealed that the expression levels of many genes in the ABA and JA signaling pathways exhibited significant differences between the OsJAZ1-overexpression plants and wild-type ZH11 under drought stress treatment. Quantitative real-time PCR confirmed the expression profiles of some of the differentially expressed genes, including OsNCED4, OsLEA3, RAB21, OsbHLH006, OsbHLH148, OsDREB1A, OsDREB1B, SNAC1, and OsCCD1. These results together suggest that OsJAZ1 plays a role in regulating the drought resistance of rice partially via the ABA and JA pathways.
