All treatments adversely affected chlorophyll fluorescence kinetics, antioxidant enzyme activities, rice grain composition and yield. The results showed that in DNF the antibiotic was accumulated 627% more than NF treatment in rice grains while in leaves there was no significant difference under both treatments. The proteomic revealed that differentially expressed identified proteins were involved in carbohydrate metabolism, amino acid metabolism, photosynthesis and mRNA binding. However, the metabolomics results showed that the abundance of metabolites related to RNA biosynthesis and amino acid metabolism were more affected. The disruptions caused in rice plant under DNF treatment become more severe, this makes it more susceptible than individual D and NF treatment.

To characterize reactive nitrogen species (RNS)-dependent acetylation profiles in avirulent/virulent (avr/vr) P. infestans, a transient gene expression, ChIP and immunoblot analyses, and nitric oxide (NO) emission by chemiluminescence were used in combination with the pharmacological approach.

Previous research on early protein dynamics induced by oligogalacturonides (OGs), pectin fragments acting as damage-associated molecular patterns (DAMPs), revealed significant phosphorylation changes in several proteins. Among them, the subunit C of the vacuolar H+-ATPase, known as DE-ETIOLATED 3 (DET3), was selected to elucidate its role in the OG-triggered immune response. The Arabidopsis det3 knockdown mutant exhibited defects in H2O2 accumulation, mitogen-activated protein kinases (MAPKs) activation, and induction of defense marker genes in response to OG treatment.

Our results suggest a compromised ability of the det3 mutant to maintain a primed state over time, leading to a weaker defense response when the plant is later exposed to the fungal pathogen. Using fluorescently labelled OGs, we demonstrated that endocytosis of OGs was less efficient in the det3 mutant, implicating DET3 in the internalization process of OGs.

Conducted in a factorial design, the experiment examined pepper plants under conditions of N sufficiency and deficiency, with and without Si supplementation (0.0 mM and 2.0 mM).

In Saccharomyces cerevisiae, the tandem zinc-finger protein Cth2 post-transcriptionally regulates gene expression under conditions of iron deficiency by controlling the levels of mRNAs that code for non-essential ferroproteins. The molecular mechanism involves Cth2 binding to AU-rich elements present in the 3′ untranslated region of target mRNAs, negatively affecting their stability and translation. Arabidopsis thaliana has two TZF proteins homologous to yeast Cth2, C3H14 and C3H15, which participate in cell wall remodelling. The present work examines the expression of representative metal homeostasis genes with putative AREs in plants with altered levels of C3H14 and C3H15 grown under varying metal availabilities. The results suggest that C3H15 may act as a post-transcriptional plant modulator of metal adequacy, as evidenced by the expression of SPL7, the main transcriptional regulator under copper deficiency, and PETE2, which encodes plastocyanin. In contrast to S. cerevisiae, the plant C3H15 affects copper and zinc homeostasis rather than iron. When grown under copper-deficient conditions, adult C3H15OE plants exhibit lower chlorophyll content and photosynthetic efficiency compared to control plants, suggesting accelerated senescence. Likewise, metal content in C3H15OE plants under copper deficiency shows altered mobilization of copper and zinc to seeds. These data suggest that the C3H15 protein plays a role in modulating both cell wall remodelling and metal homeostasis.

In this study, systematic analyses of the morphology, physiology, and transcriptome changes in grapevine leaves and roots under post-waterlogging and GR24 (a synthetic analog of SL) treatments were performed. Morphological and physiological changes in grapevines in response to post-waterlogging stress, including leaf wilting and yellowing, leaf senescence, photosynthesis inhibition, and increased anti-oxidative systems, could be alleviated by the application of GR24. Moreover, transcriptome analysis revealed that the primary gene functions induced by post-waterlogging stress changed over time; however, they were consistently associated with carbohydrate metabolism. The GR24-induced leaf genes were closely associated with carbohydrate metabolism, photosynthesis, antioxidant systems, and hormone signal transduction, which were considered vital aspects that were influenced by GR24 in grapevine to induce post-waterlogging tolerance. Concerning the roots, an enhancement of microtubules and cytoskeleton for cell construction in GR24 application was proposed to facilitate root system recovery after waterlogging.
