This study analyzes the effects of methyl jasmonic acid (MeJA) and salicylic (SA) on defensive responses banana cv. Grand Nain against Black Leaf Streak Disease (BLSD), caused by Mycosphaerella fijiensis. The metabolic were analyzed using HPLC NMR. With exception rutin, all compounds identified as phenylphenalenones. Application MeJA SA resulted in an increase level irenolone hydroxyanigofurone production. Furthermore, was observed to induce de novo synthesis 2-(4′-hydroxyphenyl)-1,8-naphthalic anhydride, 2-(4′-methoxyphenyl)-1,8-naphthalic 7-(4′-hydroxyphenyl) naphthal-8-formyl-1-carboxylic anhydride. Molecular analysis revealed a significant upregulation some genes implicated phenolic compound lipoxygenase but not ones PR proteins. MeJA-treated leaves showed improved resistance BLSD. results suggest that may serve effective protective strategy most damaging disease, providing potential for protecting crops.

Biochemical and molecular mechanisms have been essential to reduce various insect attacks on plants. The biochemical methods are wide involving direct indirect defenses. defensive chemical substances secreted effectively the wound caused by herbivores (insects phytopathogens) Plants responded producing VOCs which draw natural enemies of insects phytopathogens. progress observed in cognition stimulus plants their potential control responses is characterized modification shifts our attention development endogenous resistance preserving crops. main objective implementing a biotechnological mechanism crop production employ durable multimechanistic alternatives pests via plant produces upon encountering attack.

This paper discusses the mechanisms by which fungi manipulate plant physiology and suppress defense responses producing effectors that can target various host proteins. Effector-triggered immunity effector-triggered susceptibility are pivotal elements in complex molecular dialogue underlying plant-pathogen interactions. Pathogen-produced effector molecules possess ability to mimic pathogen-associated patterns or hinder binding of pattern recognition receptors. Effectors directly nucleotide-binding domain, leucine-rich repeat receptors, downstream signaling components defense. Interactions between these receptor-like kinases plants critical this process. Biotrophic adeptly exploit networks key hormones, including salicylic acid, jasmonic abscisic ethylene, establish a compatible interaction with their hosts. Overall, highlights importance understanding interplay fungal develop effective strategies for disease management.

This study investigates the molecular mechanisms by which Hariman mitigates damage and productivity losses caused Cucumber Aphid-Borne Mosaic Virus (CABMV) in passion fruit genotypes 'FB300' 'H09-110/111' under greenhouse field conditions Rio de Janeiro, Brazil. treatment induced upregulation of key defense genes phytohormones response to CABMV infection, enabling treated plants counteract virus-induced developmental impairments effectively. The relative accumulation disease severity were significantly reduced, with showing no decline growth parameters such as height, leaf count, flower production, or set. Over 18 months, total increased 65.7% 114% for 44% 80% after one two applications Hariman, respectively. Notably, infected outperformed healthy grown similar conditions, underscoring biofertilizer's dual role promoting plant while enhancing resistance biotic stressors. These findings indicate that stimulates robust induces expression defense-related PR-3, SOD, POD12, PAL, LOX2 alongside phytohormone-associated SAUR20 GA2ox across different genotypes. adoption these sustainable technologies holds significant potential face diseases severely threaten this crop.

ABSTRACT Clubroot caused by Plasmodiophora brassicae , a soil‐borne pathogen, threatens cruciferous plants, resulting in severe yield reductions. To identify genes and metabolites associated with clubroot resistance susceptibility, we performed metabolome transcriptome analyses of Brassica rapa inbred line CRBJN3‐2 inoculated resistant susceptible P . strains. Co‐expression network analysis revealed that trigonelline accumulation, linked to the nicotinic acid nicotinamide metabolic pathways, was significantly higher clubroot‐susceptible plants. Furthermore, applying externally aggravated both B. Arabidopsis thaliana Overexpression nicotinate N‐methyltransferase gene ( BrNANMT ) responsible for conversion from these plants increased disease while loss this gene's function resulted improved resistance. Our study is first reveal promoting development as susceptibility can be used marker metabolite response P. infection. Gene editing provides new insights crops clubroot.

Sulfate transporters (SULTRs) are key players that regulate sulfur acquisition and distribution within plants, thereby influencing cellular redox hemostasis under pathogen attacks, such as Alternaria brassicicola (Ab). In this study, a total of 23 BolSULTR (Brassica oleracea SULTR) genes were identified from the Brassica genome. These BolSULTRs distributed across nine chromosomes, with all collinear gene pairs undergoing purifying selections. Phylogenetic analysis reveals SULTR family is evolutionarily conserved among plant kingdoms. qRT-PCR demonstrated expression varies different organs modulated by hormonal signals. Furthermore, transcriptome several whose levels depressed in Ab-challenged leaves broccoli. Among them, BolSULTR2;1 emerged player plant’s response to Ab. Virus-induced silencing (VIGS) BolSULTR2;1s resulted elevated glutathione (GSH) enhanced tolerance Taken together, these findings underscore role maintaining homeostasis enhancing disease resistance, suggesting its potential target for genome editing develop broccoli varieties improved tolerance.
