Published: Feb. 16, 2025

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.

Enhancing Passion Fruit Resilience: The Role of Hariman in Mitigating Viral Damage and Boosting Productivity in Organic Farming Systems

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(5), P. 2177 - 2177

Published: Feb. 28, 2025

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.

Metabolomics and Transcriptomics Reveal the Function of Trigonelline and Its Synthesis Gene BrNANMT in Clubroot Susceptibility of Brassica rapa

Plant Cell & Environment, Journal Year: 2025, Volume and Issue: unknown

Published: March 13, 2025

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.

Genome-Wide Identification of the Sulfate Transporter Gene Family Reveals That BolSULTR2;1 Regulates Plant Resistance to Alternaria brassicicola Through the Modulation of Glutathione Biosynthesis in Broccoli

Antioxidants, Journal Year: 2025, Volume and Issue: 14(4), P. 496 - 496

Published: April 20, 2025

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.

Identification of critical transition signal (CTS) to characterize regulated stochasticity during ABA-induced growth-to-defense transition

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: April 24, 2025

Abscisic acid (ABA) plays a central role in regulating plant responses to abiotic stress. It orchestrates complex regulatory network that facilitates the transition from growth defense. Understanding molecular mechanisms underlying this ABA-induced defense is essential for elucidating adaptive strategies under environmental stress conditions. In study, we used refined dynamic biomarker (DNB) approach quantitatively identify critical signal (CTS) and characterize regulated stochasticity during Arabidopsis thaliana. By integrating high-resolution time-series RNA-seq data with analysis, identified set of DNB genes serve as key regulators transition. The phase was precisely at ninth time point (6 h after treatment), which marks crucial switch growth-dominated -oriented state. Gene Ontology (GO) enrichment analysis revealed significant overrepresentation defense-related biological processes, while STRING strong functional interactions between differentially expressed (DEGs) highlighted hubs. particular, hub such PIF4, TPS8, NIA1, HSP90-5 were potential master ABA-mediated activation, highlighting their importance adaptation. network-driven transcriptomic study provides new insights into basis transitions identification CTS perspective on conceptual framework improving crop resistance. addition, establishment comprehensive database ABA-responsive represents valuable resource future research adaptation resilience.
