Abstract

Drought is a major abiotic stress that occurs frequently due to climate change, severely hampers agricultural production, and threatens food security. In this study, the effect of drought-tolerant PGPRs, i.e., PGPR-FS2 and PGPR-VHH4, was assessed on wheat by withholding water. The results indicate that drought-stressed wheat seedlings treated with PGPRs-FS2 and PGPR-VHH4 had a significantly higher shoot and root length, number of roots, higher chlorophyll, and antioxidant enzymatic activities of guaiacol peroxidase (GPX) compared to without PGPR treatment. The expression study of wheat genes related to tryptophan auxin-responsive (TaTAR), drought-responsive (TaWRKY10, TaWRKY51, TaDREB3, and TaDREB4) and auxin-regulated gene organ size (TaARGOS-A, TaARGOS-B, and TaARGOS-D) exhibited significantly higher expression in the PGPR-FS2 and PGPR-VHH4 treated wheat under drought as compared to without PGPR treatment. The results of this study illustrate that PGPR-FS2 and PGPR-VHH4 mitigate the drought stress in wheat and pave the way for imparting drought in wheat under water deficit conditions. Among the two PGPRs, PGPR-VHH4 more efficiently altered the root architecture to withstand drought stress.

从温泉中分离出的 PGPR 可增强小麦（Triticum aestivum L.）对干旱胁迫的抵抗力。

干旱是一种主要的非生物胁迫，因气候变化而频繁发生，严重阻碍了农业生产，并威胁到粮食安全。本研究评估了耐旱 PGPRs（即 PGPR-FS2 和 PGPR-VHH4）通过扣水对小麦的影响。结果表明，与未施用 PGPRs-FS2 和 PGPR-VHH4 的小麦相比，施用 PGPRs-FS2 和 PGPR-VHH4 的干旱胁迫小麦幼苗的芽和根的长度、根的数量、叶绿素和愈创木酚过氧化物酶（GPX）的抗氧化酶活性均显著提高。对小麦色氨酸辅助因子反应性（TaTAR）、干旱反应性（TaWRKY10、TaWRKY51、TaDREB3 和 TaDREB4）和辅助因子调控基因器官大小（TaARGOS-A、TaARGOS-B 和 TaARGOS-D）相关基因的表达研究表明，在干旱条件下，PGPR-FS2 和 PGPR-VHH4 处理小麦的表达量明显高于未进行 PGPR 处理的小麦。本研究结果表明，PGPR-FS2 和 PGPR-VHH4 可减轻小麦的干旱胁迫，为缺水条件下小麦的抗旱工作铺平了道路。在这两种 PGPRs 中，PGPR-VHH4 能更有效地改变根系结构，以抵御干旱胁迫。

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.
