Abstract

With the intensification of climate change coupled with the inadequate agricultural management in certain regions, plants face numerous challenges due to various abiotic stresses. Stress associated proteins (SAPs) are essential functional genes in plants for coping with stress. This research provides a functional analysis of OsSAP17, a protein belonging to the SAP family in rice. The expression level of OsSAP17 was induced under drought, salt stress and ABA treatment. Subcellular localization analysis revealed that the OsSAP17 protein was distributed in both the cytoplasm and nucleus. The ectopic expression of OsSAP17 significantly increased the capacity to withstand drought and salt stress in both transgenic yeast and Arabidopsis. Additionally, the ectopic expression of OsSAP17 led to notable changes in the expression of Arabidopsis ABA-related genes, including AtNCED3, AtABA2, and AtSnRK2.2. These results indicated that OsSAP17 was able to positively regulate drought and salt tolerance in plants. The insights from this study provided a fundamental understanding of the role of OsSAP17 in abiotic stress response mechanisms and were potentially valuable for breeding crops with enhanced stress tolerance.

期刊介绍： Plant Physiology and Biochemistry publishes original theoretical, experimental and technical contributions in the various fields of plant physiology (biochemistry, physiology, structure, genetics, plant-microbe interactions, etc.) at diverse levels of integration (molecular, subcellular, cellular, organ, whole plant, environmental). Opinions expressed in the journal are the sole responsibility of the authors and publication does not imply the editors'' agreement. Manuscripts describing molecular-genetic and/or gene expression data that are not integrated with biochemical analysis and/or actual measurements of plant physiological processes are not suitable for PPB. Also "Omics" studies (transcriptomics, proteomics, metabolomics, etc.) reporting descriptive analysis without an element of functional validation assays, will not be considered. Similarly, applied agronomic or phytochemical studies that generate no new, fundamental insights in plant physiological and/or biochemical processes are not suitable for publication in PPB. Plant Physiology and Biochemistry publishes several types of articles: Reviews, Papers and Short Papers. Articles for Reviews are either invited by the editor or proposed by the authors for the editor''s prior agreement. Reviews should not exceed 40 typewritten pages and Short Papers no more than approximately 8 typewritten pages. The fundamental character of Plant Physiology and Biochemistry remains that of a journal for original results.
