Abstract	Plants have evolutionarily established resistance responses to a variety of abiotic stress conditions, in which ABA mediates the integrated regulation of these stress responses. Numerous proteins function at the transcription level or at the protein level when contributing to controls of the ABA signaling process.

Abstract	Thaumatin was isolated as a sweet-tasting protein. Arabidopsis has over 20 Thaumatin-Like Protein (TLP)/Osmoti-Like Protein (OLP) genes that belong to the PR5 family. Although biotic stress-related functions of TLPs have been reported from transgenic lines expressing TLPs, it is nonetheless necessary to investigate genetic phenotypes produced by defects in the TLP genes. In this report, four TLP genes were selected based on sequence similarities (Thau1/2/3/4), and the corresponding mutant thau1/2/3/4 was examined for biotic and abiotic stress responses. The thau1/2/3/4 mutant showed increased susceptibility to the Pseudomonas syringae pv. tomato DC3000 infection, and reduced sensitivity to the ABA and drought stress treatments. Each of the four thaumatin genes showed different gene expression patterns for ABA treatment. Moreover, ABA-inductions of Thau1/2/3/4 were largely dependent on the intact ABA signaling pathway mediated by PYR/PYL receptors. Among the many ABA-responsive genes affected by the defects of Thau1/2/3/4, reduced expression of P5CS1 with decreased accumulation phenotype of prolines indicates that compromised proline synthesis may be associated with the stress phenotypes of thau1/2/3/4. Our data suggest that Thau1/2/3/4 have a function in both biotic stress and abiotic stress signal transduction through the regulation of proline synthesis.

Article ; Online: Arabidopsis OSMOTIN 34 Functions in the ABA Signaling Pathway and Is Regulated by Proteolysis

Eun-Joo Park / Tae-Houn Kim

International Journal of Molecular Sciences, Vol 22, Iss 7915, p

2021 Volume 7915

Abstract	Plants have evolutionarily established resistance responses to a variety of abiotic stress conditions, in which ABA mediates the integrated regulation of these stress responses. Numerous proteins function at the transcription level or at the protein level when contributing to controls of the ABA signaling process. Although osmotin is identified as a salt-inducible protein, its function in the abiotic stress response is yet to be elucidated. To examine the role of Arabidopsis OSMOTIN 34 ( OSM34 ) in the ABA signaling pathway, a deletion mutant osm34 generated by a CRISPR/Cas9 system and the double mutant osm34 osml ( osmotin 34-like ) were analyzed for various ABA responses. Both osm34 and osm34 osml showed reduced levels of ABA responses in seeds and leaves. Moreover, proline level and expression of the proline biosynthesis gene P5CS1 was significantly reduced in osm34 osml. Interestingly, OSM34 binds to SKP2A, an F-Box protein whose transcription is induced by ABA. The protein stability of OSM34 was determined to be under the control of the 26S proteasome. In conclusion, our data suggest that OSM34 functions as a positive regulator in the generation of ABA responses and is under post-translational control.

Abstract	Most eukaryotic genes undergo various post-transcriptional processing events before being translated into proteins. Alternative splicing (AS) is one such event and is an essential mechanism in post-transcriptional gene regulation that allows multiple mRNA variants to be expressed from a single pre-mRNA, thereby expending the functional capacity of a gene as well as the organismal complexity. With the advancement of next-generation sequencing technologies, extensive transcriptomic resources in plant species have determined crucial roles of AS in the regulation of developmental processes and adaption to environmental stresses. We review here recent studies of AS events and splicing factors that specifically affect abiotic-stress tolerance in crop plants, including other agricultural traits. Understanding how alternative splicing modulates plant development and abiotic-stress responses may provide new insights for improving the environmental fitness and productivity of crop plants.

Abstract	When plants are subjected to unfavorable environmental conditions, overall gene expression in stressed cells is altered from a programmed pattern for normal development to an adaptive pattern for survival. Rapid changes in plant gene expression include production of stress responsive proteins for protection as well as reduction of irrelevant proteins to minimize energy consumption during growth. In addition to the many established mechanisms known to modulate gene expression in eukaryotes, a novel strategy involving tRNA-derived fragments (tRFs) was recently reported to control gene expression. In animals, tRFs are shown to play a certain role in infected or cancer cells. However, tRFs are expected to function in the regulation of gene expression against abiotic stress conditions in plants. Moreover, the underlying mechanism linking up-regulation of tRFs under stress conditions with the stress tolerant response remains unknown. In this review, the biogenesis and putative function of diverse tRFs in abiotic stress signaling are discussed with a focus on tRFs as a transcriptional/post-transcriptional/translational regulator.

Article ; Online: Production of ABA responses requires both the nuclear and cytoplasmic functional involvement of PYR1.

Abstract	Abscisic acid (ABA) enhances stress tolerant responses in plants against unfavorable environmental conditions. In Arabidopsis, ABA promotes interactions between PYR/PYL/RCARs and PP2C, thereby allowing SnRK2s to phosphorylate downstream components required for the regulation of gene expression or for gating ion channels. Because PYR1 is known to localize to nucleus and cytoplasm it is a question whether nuclear or cytoplasmic PYR1 confer different functions to the ABA signaling pathway, as has been previously shown for regulatory proteins. In order to answer this question, transgenic lines expressing nuclear PYR1 were generated in an ABA insensitive mutant background. Enforced nuclear expression of PYR1 was examined by confocal microscopy and western blot analysis. Physiological analyses of the transgenic lines demonstrated that nuclear PYR1 is sufficient to generate ABA responses, such as, the inhibition of seed germination, root growth inhibition, the induction of gene expression, and stomatal closing movement. However, for the full recovery of ABA responses in the mutant background cytoplasmic PYR1 was required. The study suggests both nuclear and cytoplasmic PYR1 participate in the control of ABA signal transduction.

Abstract	Abiotic and biotic stresses are the major factors that negatively impact plant growth. In response to abiotic environmental stresses such as drought, plants generate resistance responses through abscisic acid (ABA) signal transduction. In addition to the major role of ABA in abiotic stress signaling, ABA signaling was reported to downregulate biotic stress signaling. Conversely recent findings provide evidence that initial activation of plant immune signaling inhibits subsequent ABA signal transduction. Stimulation of effector-triggered disease response can interfere with ABA signal transduction via modulation of internal calcium-dependent signaling pathways. This review overviews the interactions of abiotic and biotic stress signal transduction and the mechanism through which stress surveillance system operates to generate the most efficient resistant traits against various stress condition.
