Heat stress (HS) has become a major factor limiting crop yields worldwide. HS inhibits plant growth by ROS accumulation, and NADPH oxidases (Rbohs) are producers in plants. Here, we show that CRISPR/Cas knockout of the OsRbohB (OsRbohB-KO) significantly increased rice tolerance to imposed at various different stages. We produced OsRbohB-KO OsRbohB-overexpression (OsRbohB-OE) lines japonica cultivar, Nipponbare. Compared with nontransgenic wild-type (WT) plants, showed significant increase chlorophyll contents (5.2%-58.0%), (48.2%-65.6%) grain yield (8.9%-20.5%), while reducing HS-induced accumulation seeds (21.3%-33.0%), seedlings (13.0%-30.4%), anthers (13.1%-20.3%) grains (9.7%-22.1%), under conditions. Analysis components revealed plants was due starch synthetase activity, spikelets per panicle (2.0%-9.3%), filled (4.8%-15.5%), percentage (2.4%-6.8%) 1000-grain weight (2.9%-7.4%) conditions during reproductive stage. Grain milling appearance quality, content were also mature Furthermore, upregulated expression levels heat shock-related genes, OsHSP23.7, OsHSP17.7, OsHSF7 OsHsfA2a, long-term Conversely, OsRbohB-OE resulted phenotypes opposite most cases. Our results suggest suppression provides an effective approach for alleviating damage improving quality

Higher-fungi xylotrophic basidiomycetes are known to be the reservoirs of bioactive metabolites. Currently, a great deal attention has been paid exploitation mycelial fungi products as an innovative alternative in crop protection. No data exist on mechanisms behind interaction between mushrooms’ glycopolymeric substances and plants. In this study, effects basidiomycete metabolites morphophysiological biochemical variables wheat plants have explored. Wheat (Triticum aestivum L. cv. Saratovskaya 29) seedlings were treated with extracellular polysaccharides (EPSs) isolated from submerged cultures twenty strains assigned 13 species 8 genera. The EPS solutions at final concentrations 15, 40, 80 mg/L applied followed by their growth for 10 days. plant samples, biomass, length coleoptile, shoot root, root number, rate lipid peroxidation malondialdehyde concentration, content hydrogen peroxide, total phenols measured. peroxidase superoxide dismutase activity defined. Most preparations improved biomass yields, well morphological parameters examined. application enhanced activities antioxidant enzymes decreased oxidative damage lipids. Judging its overall effect indices redox system plants, concentration 40 shown most beneficial compared other concentrations. This study proves that novel bioformulations based mushroom EPSs can developed effective antioxidative response.

Many natural products (NPs) exhibit strong antioxidant activity, making them valuable for various applications. In this context, the emergence of deep eutectic solvents (DESs) is expected to help address growing demand innovative, efficient, and more sustainable methods NPs extraction. DESs are designer that provide higher yields enhance activity extracted phytochemicals compared with conventional volatile organic solvents. Antioxidant naturally occurring molecules can also form DESs, either as hydrogen bond donors (HBD) or acceptors (HBA), creating DES (NADES) inherent activity. Thus, containing exert synergistic effects, entire system a promising active ingredient food industry The synergy arises from enhanced solubilization stabilization in through bonding, ionic interactions, van der Waals forces. Collectively, enable effectively neutralize oxidants (such ROS free radicals) regulate their reactions other molecules, achieving up 3-fold increase extracts regular vitro.

Specifically, changes in phytochemicals and gene activity related to pathogenesis-related phenylpropanoid pathway genes tomato plants ( Solanum lycopersicum L.) during a period 2–14 days post-inoculation (dpi). According TEM investigation coat protein sequence analysis, purified TMV Egyptian AM isolate (PP133743) has rod-shaped structure diameter around 110 nm. RT-qPCR analysis revealed that PR-1 showed an initial increase after infection, as seen time-course analysis. In contrast, PR-2 was consistently elevated throughout suggesting stronger reaction suppressing PAL expression at 6 14 dpi. levels HQT CHS transcripts exhibited alternating patterns up-regulation down-regulation different time intervals.
