Abstract Highly saline soils negatively affect crop growth, especially rice. Although chemical approaches can be used, they damage the environment and sustainability of agriculture. Thus, a biological candidate should assessed. Therefore, study evaluated impact nitrogen (N)-fixing purple non-sulfur bacteria (PNSB) strains on improving soil properties, nutrient uptake, rice yield highly in My Xuyen district, Soc Trang province. The N-fixing PNSB were hypothesized to boost availability reduce salinity, leading greater growth yield. A pot experiment was arranged completely randomized block design with two factors, including four N applying rates (100, 75, 50, 0%) Rhodobacter sphaeroides (no added bacteria, single bacterial strain R. S01, S06, mixture S01 S06). results showed that adding mixed S06 improved plant height by 4.02–10.4% (the first season) 3.86–6.84% second season). Under application NH 4 + increased 31.8–50.5%, while Na decreased 16.0–25.7% both seasons. From there, total uptake also 34.9–73.8% went down 19.1–26.5% via This led traits, such as number panicles per pot, seeds panicle, filled seed rate Ultimately, grain 10.2–14.8% under greenhouse condition. In conclusion, current successfully provided potent N-fixer for improvements health. this liquid biofertilizer further tested field trails.

Ethylene response factors (ERFs) are transcription that essential in modulating drought stress responses plants such as Arabidopsis and rice. However, the functional role of ERF wheat remains unclear. We identified 33 genes under using transcriptomic analysis categorized them into eight subfamilies (I–VIII). Among them, 12 drought-responsive candidate were upregulated, TaERF13-2B was selected for further analysis. overexpression resulted significantly reduced survival rates conditions with decreased expression stress-responsive antioxidant enzyme genes, indicating gene elevated sensitivity transgenic . In wheat, increased malondialdehyde accumulation, chlorophyll proline levels, activity. Furthermore, antioxidant-related suppressed, suggesting negatively regulates to stress. The interactions between TaCIPK9 confirmed yeast two-hybrid bimolecular fluorescence complementation. Overall, these discoveries deepen our insights family contribute elucidation wheat.

Water stress is a critical factor limiting the growth and development of Capsicum annuum. Flavonoids lignin are important secondary metabolites that serve as signaling molecules in plant responses. However, effects regulatory mechanisms flavonoids under water annuum remain unknown. The present study focused on drought waterlogging morphology, hydrogen peroxide, relative chlorophyll (SPAD), well enzyme activities, metabolite contents, gene expression related to flavonoid metabolic pathways results showed stresses variety ‘Shuyu2’ significantly reduced height, stem thickness, single-fruit weight, increased fruit shape coefficients. Drought H2O2 SPAD content, enhanced activity levels enzymes (phenylalanine deaminase, cinnamate 4-hydroxylase, coenzyme A ligase, peroxidase, polyphenol oxidase), up-regulated genes, phenylalanine deaminase (PAL), trans-cinnamate monooxygenase (C4H), chalcone isomerase (CHI), mangiferyl hydroxycinnamoyltransferase (HCT), while also promoting accumulation (total phenolics, flavonoids, lignin) have restorative effect stress. continuous increase then decrease was observed. Waterlogging activities above-mentioned enzymes, but genes were selectively down-regulated, e.g., C4H, 4CL, peroxidase (POD), which resulted inhibition synthesis lignin, total phenols. These indicate drought-tolerant, waterlogging-sensitive variety. Meanwhile, pathway key response annuum, improves theory tolerance breeding
