Plant growth-promoting bacteria (PGPB) can sustainably foster plant growth in agricultural systems and mitigate adverse effects of stress on plants. This is the first study to investigate the combined use of <em>Azospirillum brasilense</em> (<em>Ab</em>) and <em>Nitrospirillum amazonense</em> (<em>Na</em>), two microorganisms widely applied in agricultural systems, aiming to elucidate their effects on the nutritional status, biochemical responses, and productive parameters of sugarcane. Greenhouse experiments were conducted under controlled water and temperature conditions with four treatments: application of <em>Ab, Na</em>, or <em>Ab</em> + <em>Na</em> (Mix) or no PGPB application (control). Sugarcane was cultivated until the middle of the rapid growth stage. To validate the results, the greenhouse trials were replicated under field conditions at two sites (Maracaí-SP and Pradópolis-SP). The results showed that the inoculation of sugarcane with plant growth-promoting bacteria (PGPB), particularly <em>Ab</em> and Mix, enhanced nutritional aspects, especially N content. These increases were significant under greenhouse (<em>p</em> ≤ 0.05) and field conditions (<em>p</em> ≤ 0.10). Additionally, inoculation reduced oxidative stress and improved photosynthetic parameters, such as net photosynthetic rate, water use efficiency, and carboxylation efficiency. These cascading effects contributed to significant gains in crop productivity, with an average increase in stalk yield of 10.9 % for <em>Ab</em> and 12.2 % for Mix across both environments. Similarly, there was an increase in sugar yield per hectare, with gains of 13.3 % for <em>Ab</em> and 13.7 % for Mix compared to the control. These findings highlight the potential of PGPB as a sustainable strategy to enhance crop productivity and resilience, contributing to environmentally balanced agricultural systems. Although the benefits of PGPB were evident, differences between <em>Ab</em> and Mix were not pronounced. Therefore, additional studies are needed to explore the potential of these combinations under adverse conditions, when their effects could be more pronounced.</div></div>","PeriodicalId":20234,"journal":{"name":"Plant Physiology and Biochemistry","volume":"225 ","pages":"Article 109980"},"PeriodicalIF":6.1,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143931867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, aimed to test whether the down-regulation of <em>GhAIP10</em> genes can stimulate the cotton plants in a manner similar to those observed in <em>A. thaliana</em>.

The down-regulation of the <em>GhAIP10.1</em> and <em>GhAIP10.2</em> genes was confirmed by real-time RT-PCR. Phenotypic and physiological analyses revealed that these transgenic lines exhibited earlier production and opening of flower buds, increased vegetative growth over time and root biomass, no reduction in susceptibility to root-knot nematodes, and improved drought tolerance indicated by a higher photosynthetic rate and better intrinsic water-use efficiency.

GSTs are potentially responsible for the conversion of GSH into S-(2-carboxypropyl) glutathione, an intermediate in the biosynthesis of CSOs. Here, a GST gene, <em>AcGSTU27</em>, was determined to be participating in CSOs biosynthesis in onion. <em>AcGSTU27</em> overexpression (OE) increased the CSOs biosynthesis in onion callus. Exogenous GSH promoted the accumulation of CSOs, especially in <em>AcGSTU27</em>-OE lines. Furthermore, abiotic stress promoted CSOs accumulation in onion.

The CSOs contents of <em>AcGSTU27-</em>OE and wild-type (WT) callus were significantly increased under Cu, Cd, and glufosinate treatments. Moreover, the increase in CSOs levels in <em>AcGSTU27</em>-OE materials was higher than that in the WT.

A notable member of this family is the auxin methyltransferase IAMT which uses indole-3-acetic acid (IAA) as the substrate. This study aims to determine whether methyl phenylacetate (MePAA), the methyl ester of another auxin, phenylacetic acid (PAA), is synthesized by SABATH methyltransferases. Potato (<em>Solanum tuberosum</em> L. cv. Désirée) was chosen as the primary model because it produces MePAA exclusively in flowers. Based on the structural similarity of IAA and PAA, our initial hypothesis was that MePAA is synthesized by an IAMT-like enzyme. The potato genome contains two <em>IAMT-like</em> genes. However, their recombinant enzymes expressed in <em>Escherichia coli</em> were shown to catalyze the methylation of IAA but not PAA, thus rejecting our initial hypothesis. Among the 23 potato <em>SABATH</em> genes, two exhibited flower-specific expression. One was excluded because it had already been identified as an IAMT. <em>In vitro</em> assays of the enzyme encoded by the other gene, <em>StSABATH6</em>, confirmed its catalytic activity against PAA. Consequently, this enzyme was renamed StPAAMT. Notably, StPAAMT has an ortholog in both cultivated and wild tomatoes. The gene from tomato (<em>Solanum lycopersicum</em>), <em>SlPAAMT</em>, was verified to encode PAA methyltransferase. Further genomic and phylogenetic analyses of five <em>Solanum</em> species showed that the <em>PAAMT</em> gene was likely absent in eggplant (<em>Solanum melongena</em>), implying its origin in the common ancestor of potato and tomato. The structural analysis identified key amino acids associated with the substrate specificity of PAAMT.
