Abstract Plants produce a wide variety of secondary metabolites to sustain and protect themselves against range stresses. Among these metabolites, tannins are one the most abundant polyphenolic compounds, accounting for 25% dry weight leaves, roots bark woody plants, but also in flowering seed-producing plants. The presence organs serves plants herbivorous pathogenic attack through their antidigestive antimicrobial properties. In addition, play role regulating plant growth development by inhibiting consumption unripe fruits due astringency. several studies have revealed various roles them under environmental Tannins can be classified into condensed (CTs), hydrolysable (HTs) phlorotannins. They synthesised via acetate–malonate shikimic acid pathways. Their accumulation is regulated transcription factors during normal different stress conditions. Despite multiple life, information on regulation tannin metabolism defence-related phytohormones very limited. To cope with biotic abiotic stresses, responses such as salicylic (SA), jasmonic (JA), ethylene (ET) abscisic (ABA), which act regulators production adverse This review focuses production, moreover its occurrence, defence potential based recent relevant data.

Fusaric acid-evoked oxidative stress affects plant defence system by inducing biochemical changes at subcellular level

Plant Cell Reports, Год журнала: 2023, Номер 43(1)

Опубликована: Дек. 18, 2023

Abstract Fusaric acid (FA) is one of the most harmful phytotoxins produced in various plant–pathogen interactions. Fusarium species produce FA as a secondary metabolite, which can infect many agronomic crops at all stages development from seed to fruit, and production further compromise plant survival because its phytotoxic effects. exposure adversely affects growth, crop yield. plants leads generation reactive oxygen (ROS), cause cellular damage ultimately cell death. Therefore, FA-induced ROS accumulation has been topic interest for researchers understand interactions defence responses. In this study, we reviewed FA-mediated oxidative stress ROS-induced responses antioxidants, well hormonal signalling plants. The effects phytotoxicity on lipid peroxidation, physiological changes ultrastructural subcellular levels were reported. Additionally, DNA damage, death adverse photosynthesis have explained. Some possible approaches overcome also discussed. It concluded that affect enzymatic non-enzymatic antioxidant system regulated by phytohormones. are associated with other photosynthetic, genotoxic modifications Graphical abstract

The Role of Salicylic, Jasmonic Acid and Ethylene in the Development of the Resistance/Susceptibility of Wheat to the SnTox1-Producing Isolate of the Pathogenic Fungus Stagonospora nodorum (Berk.)

The SnTox1 effector is a virulence factor of the fungal pathogen Stagonospora nodorum (Berk.), which interacts with host susceptibility gene Snn1 in gene-for-gene manner and causes necrosis on leaves sensitive wheat genotypes. It known that salicylic acid (SA), jasmonic (JA) ethylene are key phytohormones involved plant immunity. To date, effectors various pathogens have been discovered can manipulate hormonal pathways even use hormone crosstalk to promote disease development. However, role manipulating has not studied detail. We redox status expression twelve genes two MAPK six bread cultivars insensitive or without treatment by SA, JA ethephon (ethylene-releasing agent) during infection SnTox1-producing isolate S. 1SP. results showed controls antagonism between SA JA/ethylene signaling pathways. pathway was development susceptibility, were plants resistance Sn1SP presence SnTox1-Snn1 interaction. hijacked suppress catalase activity, increase hydrogen peroxide content induce formation; it simultaneously suppresses SA. do this, reprogrammed TaMRK3 TaMRK6 TF TaWRKY13, TaEIN3 TaWRKY53b.

Tomato Biostimulation with Nanochitosan–Iodine Complexes: Enhancing Antioxidant Metabolism

Plants, Год журнала: 2025, Номер 14(5), С. 801 - 801

Опубликована: Март 5, 2025

Biostimulants are currently essential for agriculture as they increase crop productivity and quality sustainably. The aim of this work was to evaluate the effects biostimulation on application nanochitosan–iodine complexes (nCS-I) tomato plants. Leaf samples were taken analysis total protein content, photosynthetic pigments, antioxidant enzymatic activity, mineral iodine contents, gene expression, shelf life in fruit. catalase (CAT), glutathione peroxidase (GPX), ascorbate (APX), superoxide dismutase (SOD) activities increased significantly with nanochitosan (nCS) nanochitosan–potassium iodate (nCS-KIO3) iodide (nCS-KI) salts potassium (KIO3) (KI). content pigments also treatments. contents did not change Similarly, overexpression SOD, GPX, CAT genes observed. Finally, test, an phenols capacity observed This study shows that use nCS-I can modulate different transcriptional post-translational processes possible synergistic metabolism

Immunomodulating melatonin-decorated silica nanoparticles suppress bacterial wilt (Ralstonia solanacearum) in tomato (Solanum lycopersicum L.) through fine-tuning of oxidative signaling and rhizosphere bacterial community

Tomato (Solanum lycopersicum L.) production is severely threatened by bacterial wilt, caused the phytopathogenic bacterium Ralstonia solanacearum. Recently, nano-enabled strategies have shown tremendous potential in crop disease management. This study investigates efficacy of biogenic nanoformulations (BNFs), comprising silica nanoparticles (SiNPs) and melatonin (MT), controlling wilt tomato. SiNPs were synthesized using Zizania latifolia leaves extract. Further, MT containing BNFs through one-pot approach. Nanomaterials characterized standard characterization techniques. Greenhouse assays conducted to assess impact on tomato plant immunity resistance wilt. The exhibited a spherical morphology, with particle sizes ranging from 13.02 nm 22.33 for 17.63 21.79 BNFs, indicating relatively uniform size distribution consistent shape across both materials. experiments revealed that soil application outperformed SiNPs, significantly enhancing reducing incidence 78.29% plants maintaining oxidative stress homeostasis via increasing activities antioxidant enzymes such as superoxide dismutase (31.81%), peroxidase (32.9%), catalase (32.65%), ascorbate (47.37%) compared untreated infected plants. Additionally, induced salicylic acid activating defense-related genes (e.g., SlPAL1, SlICS1, SlNPR1, SlEDS, SlPD4, SlSARD1) involved phytohormones signaling High-throughput 16 S rRNA sequencing promoted growth beneficial rhizosphere bacteria (Gemmatimonadaceae, Ramlibacter, Microscillaceae, Anaerolineaceae, Chloroplast Phormidium) healthy diseased plants, while suppressing R. solanacearum abundance Overall, these findings suggest offer more promising sustainable approach managing

Effect of Fumonisin B1 on Transcriptional Profiles and Biochemical Signatures in Resistant and Susceptible Maize Shoots

Journal of Plant Growth Regulation, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 29, 2024

Fumonisin B1 (FB1) is the most harmful toxin, due to its incidence and high concentrations in maize, along with toxicity humans animals. To investigate possible mechanisms of FB1 phytotoxicity, an RNA-Sequencing based transcriptome analysis was carried out at 3 h after treatment shoots CO433 maize line resistant Fusarium verticillioides. One thousand four hundred fifty-nine differentially expressed genes were identified, 13.9% them playing a role defense cell rescue functional classes. The study transcriptional changes extended CO389 genotype susceptible F. verticillioides 48 exposure for subset thirteen involved antioxidant metabolism, mycotoxin detoxification, death regulation, hormone signaling, ubiquitination. Moreover, enzymes compounds monitored same plant material. Defense responses appeared promptly activated genotype; particularly, h, accumulation transcripts protecting from oxidative stress response processes as well ascorbate content enhanced, underlining earlier higher attitude this background counteract phytotoxic action FB1. In contrast, line, expression majority catalase, phenolics levels increased later time, conferring lower readiness mycotoxin. This work provides useful sources markers development successful disease management strategies maize.
