In the face of climate change, agriculture is increasingly challenged by shifting dynamics biotic stresses, including intensified spread pests and pathogens. Traditional control methods, often reliant on chemical pesticides, are associated with environmental degradation potential health risks. Nanoparticles (NPs) present a promising, sustainable alternative for enhancing plant resistance to potentially revolutionizing agricultural practices. This mini-review explores mechanisms through which NP-based formulations (such as metal-based NPs, chitosan, silica) induce responses bolster defences against pathogens pests. By resilience without downsides conventional NPs could support more approach crop protection. review also highlights risks in expanding use agriculture, urging studies explore these technologies managing crops changing climate.

Effects of fast and slow-wilting soybean genotypes on fall armyworm ( Spodoptera frugiperda ) growth and development

Communicative & Integrative Biology, Journal Year: 2024, Volume and Issue: 17(1)

Published: May 19, 2024

Soybean (Glycine max) is the most important plant protein source, and Fall Armyworm (FAW, Spodoptera frugiperda) considered a major pest. This study aimed to examine impact of FAW feeding on soybean accessions that vary in their water use efficiency (WUE) traits, by examining growth life history parameters along with response pest damage. were grown greenhouse exposed larval for 48 h at three different stages: V3, R3, R6. The development soybeans monitored. Results showed faster wilting grow taller have more leaves than slower accessions, but yield was higher accessions. experienced highest mortality mid-stage (R3) plants, they gained least mass early stage (V3) plants. These results can assist better understanding insect-interactions stages both implications management.

The Role of Genetic Resistance in Rice Disease Management

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(3), P. 956 - 956

Published: Jan. 23, 2025

Rice (Oryza sativa) is a crucial staple crop for global food security, particularly in Asia. However, rice production faces significant challenges from various diseases that can cause substantial yield losses. This review explores the role of genetic resistance disease management, focusing on molecular mechanisms underlying plant–pathogen interactions and strategies developing resistant varieties. The paper discusses qualitative quantitative resistance, emphasizing importance (R) genes, defense-regulator trait loci (QTLs) conferring broad-spectrum resistance. Gene-for-gene relationships rice–pathogen are examined, Xanthomonas oryzae pv. Magnaporthe oryzae. also covers recent advancements breeding techniques, including marker-assisted selection, engineering, genome editing technologies like CRISPR-Cas. These approaches offer promising avenues enhancing while maintaining potential. Understanding exploiting durable disease-resistant varieties, essential ensuring sustainable security face evolving pathogen threats changing environmental conditions.

Silicon Supplementation Reinforces Maize Defence to Defeat the Oriental Armyworm

Journal of Applied Entomology, Journal Year: 2025, Volume and Issue: unknown

Published: April 5, 2025

ABSTRACT Maize is a critical component of global food security; however, pests like the oriental armyworm ( Mythimna separata Walker) cause significant yield losses to this crop. Conventional control approaches for managing insect rely on pesticide applications, which pose environmental risks and can lead pest resistance. Thus, necessity alternative management strategies emphasised. Silicon (Si) proposed as substitute due its ability mitigate plethora biotic abiotic stresses in plants. To evaluate effectiveness Si controlling armyworm, maize plants were treated with three concentrations (T1: 500 mg/L, T2: 750 T3: 1000 mg/L) then infested larvae. The performance was assessed by evaluating larval feeding oviposition preference, mandibular morphology, survival rates weight gain. Results showed mean rate 63% T3 compared 96% control. larvae fed leaves twice that those Si‐treated leaves. Likewise, incisor length significantly shorter (177 μm) than (447 μm). Moreover, less favourable egg laying, only 20% eggs laid them. These findings indicate supplementation enhances resistance infestation armyworm. This Si‐mediated against underscores potential sustainable chemical pesticides integrated strategies.

A frameshift mutation in JAZ10 resolves the growth versus defense dilemma in rice

Proceedings of the National Academy of Sciences, Journal Year: 2024, Volume and Issue: 121(52)

Published: Dec. 18, 2024

CRISPR-Cas9 genome editing systems have revolutionized plant gene functional studies by enabling the targeted introduction of insertion-deletions (INDELs) via nonhomologous end-joining (NHEJ) pathway. Frameshift-inducing INDELs can introduce a premature termination codon and, in other instances, lead to appearance new proteins. Here, we found that mutations rice jasmonate (JA) signaling OsJAZ10 CRISPR-Cas9-based did not affect canonical JA signaling. However, type mutant with an INDEL yielded novel frameshift protein named FJ10 ( F rameshift mutation J AZ 10 ), exhibited enhanced growth and increased resistance brown planthopper attacks. Overexpression wild-type plants phenocopies mutants. Further characterization revealed interacts Slender Rice 1 (OsSLR1) F-box/Kelch 16 (OsFBK16). These interactions disrupt function OsSLR1 suppressing gibberellin-mediated OsFBK16 repressing lignin-mediated defense responses, respectively. Field experiments -expressing demonstrate this uncouples growth–defense tradeoff, opening broad avenues obtain cultivars yield without compromised defenses.
