Mode of Action of Oryzalexin D againstPyricularia oryzae

Agricultural and Biological Chemistry, 1987
The effect of oryzalexin D, which has been isolated as a group of novel phytoalexins of rice plant, on DNA, RNA, protein, lipid and chitin biosyntheses, respiration and cell membrane permeability was investigated in Pyricularia oryzae. The concentration for 50% inhibition (ED50) by oryzalexin D of the mycelial growth of P. oryzae was 230 ppm.

Zymoseptoria tritici Effectors Structurally Related to Killer Proteins UmV‐KP4 and UmV‐KP6 Inhibit Fungal Growth, and Define Extended Protein Families in Fungi

Molecular Plant Pathology, Volume 26, Issue 8, August 2025.
The fungal effectors Zt‐KP4‐1 and Zt‐KP6‐1 of Zymoseptoria tritici are structural homologues of killer toxins KP4 and KP6α of Ustilago maydis, are antifungal, and their structural homologues are widespread in fungi. ABSTRACT Fungal effectors play crucial roles in plant infection. Despite low sequence identity, they were recently discovered to belong to

Cytological aspects of incompatible and compatible interactions between rice, wheat and the blast pathogen Pyricularia oryzae

Scientia Agricola, 2016
Blast, caused by the fungus Pyricularia oryzae, is an important disease affecting rice and wheat yield worldwide. This study investigated the cytological aspects of incompatible (non-host resistance) and compatible (host resistance) rice- (R_Po) and ...

Unravelling the Severity Landscape of Brazilian Magnaporthe oryzae Triticum on Wheat Cultivars With and Without 2NVS Translocation

Plant Pathology, Volume 74, Issue 6, Page 1854-1866, August 2025.
The 2NVS translocation in wheat cultivars is no guarantee of resistance to head blast. The virulence of MoT isolates varies according to host genotype, with or without 2NVS translocation, and issues related to morphoclimatic domains. ABSTRACT Wheat blast caused by Magnaporthe oryzae Triticum (MoT) threatens wheat production, affecting plants at various

Aminoisothiazolamides, a new class of potent inhibitors of lysyl‐tRNA synthetase

Pest Management Science, Volume 81, Issue 7, Page 3956-3983, July 2025.
The present work covers a series of novel herbicidal lead structures that possess an aminoisothiazolamide scaffold as a structural key feature. Lysyl‐tRNA synthetase 1 (KRS1) was identified as the biochemical mode‐of‐action. Based on optimized and tailored synthetic approaches, a broader SAR study was carried out delivering some lead structures that ...
