CRISPR-Cas12a ribonucleoprotein-mediated gene editing in the plant pathogenic fungus Magnaporthe oryzae

STAR Protocols, 2022
Summary: Gene replacements through homologous recombination (HR) have been extensively used for functional genomic studies. However, the general efficiency of HR repair can be low in filamentous fungi and the process laborious.

Heterocyclic‐Based Fungicides: Emerging Strategies for Viable Plant Disease Control

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Heterocyclic compounds have attracted considerable attention because of their structural diversity, potent antifungal activity, and ability to interact with multiple fungal targets, offering broad‐spectrum protection against phytopathogens. Synthetic and semisynthetic/part‐natural scaffolds, particularly azole, quinoline, indole, cyclotryptamine, and ...

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, Volume 82, Issue 9, Page 8159-8170, September 2026.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

Dual Role of Acid Rain and Pyricularia oryzae on Growth, Photosynthesis and Chloroplast Ultrastructure in Rice Seedlings

Agronomy, 2022
Rice is widely planted and serves as staple food in the world, but it is often exposed to acid rain and rice blast (Pyricularia oryzae). In this work, we analyzed the effects of co-exposure to simulated acid rain (SAR) and P. oryzae on the photosynthetic
