First Report of Rice Blast Caused by Pyricularia grisea in California

Plant Disease, 1997
Rice blast, caused by Pyricularia grisea (Cooke) Sacc., generally recognized as the most important disease of rice (Oryzae sativa L.) worldwide, was first found in the Sacramento Valley of California in 1996. Symptoms observed in commercial fields during September and October consisted mainly of darkened lesions at the panicle neck node and flag leaf ...

Mining Actinomycetes' Metabolomes and Genomes for Anti‐Phytophthora infestans Compounds

Microbial Biotechnology, Volume 18, Issue 12, December 2025.
Using a comparative metabolomic and genomic approach on 63 actinomycetes, this study identified 75 compounds associated with the strains' ability to inhibit the late blight‐causing agent Phytophthora infestans. This study highlighted the promise of applying multi‐omics techniques on closely related strains differing in biological activity to pinpoint ...

Environmental Requirements for Germination and Appressorium Formation of Ascospores and Conidia of Phyllosticta citricarpa, the Causal Agent of Citrus Black Spot

Plant Pathology, Volume 74, Issue 7, Page 2108-2120, September 2025.
Cardinal temperatures for both Phyllosticta citricarpa spore germination were estimated as ~10ºC (minimum) and ~40ºC (maximum), and the optimum temperatures were ~30ºC for ascospores and ~24ºC for conidia. ABSTRACT Phyllosticta citricarpa produces ascospores and conidia that infect citrus tissues and cause citrus black spot (CBS).

Pathotypes of Pyricularia grisea in Rice Fields of Central and Southern China [PDF]

Plant Disease, 2001
Blast, caused by the fungal pathogen Pyricularia grisea, is the most devastating disease of rice worldwide. Knowledge of the pathotype composition of the pathogen in rice fields is essential for rational deployment of resistance genes in rice breeding programs. In this study, we assayed the pathotypes of the pathogen populations using samples recently

The herbicidal natural product phosphonothrixin is an inhibitor of the riboflavin biosynthetic enzyme L‐3,4‐dihydroxy‐2‐butanone‐4‐phosphate synthase

Pest Management Science, Volume 81, Issue 8, Page 4328-4335, August 2025.
An enzyme involved in vitamin B2 biosynthesis, 3,4‐dihydroxy‐2‐butanone‐4‐phosphate synthase (DHBPS), was identified as the target of the natural product phosphonothrixin, representing a novel mode of action for herbicides. Abstract BACKGROUND In our ongoing search for new and environmentally friendly chemical entities that can control weeds via new ...
