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.

Comparative Analysis of Stress Adaptation in the Yeast Microbiome of Cactus

Yeast, EarlyView.
Yeasts and related fungi isolated from cacti or nearby non‐cactus plants were characterized phenotypically and genomically, revealing differences that hint at modes of adaptation to the cactus host. ABSTRACT Together with other fungi, yeasts make up a significant component of the plant microbiome. As the planet warms, cacti expand their range.

The effects of various media on sporulation and growth of Pyricularia oryzae Cavara

Acta Mycologica, 2014
The authors have investigated the effect of many media on the development of 10 isolates of Pyricularia oryzae in order to obtain abundant sporulation, to facilitate the determination of physiological races and preparation of phytopathological tested.

Transposons as Tools for Future Genome Engineering in Yeasts and Filamentous Fungi

Yeast, EarlyView.
Applications of transposon‐based tools for genome engineering in fungi include transposon‐mediated mutagenesis and targeted genomic integration. ABSTRACT Transposons are fundamental genetic elements that have profoundly shaped the architecture of eukaryotic genomes.

Efficient gene editing with an Arg-tRNA promoter-driven CRISPR/Cas9 in the rice blast fungus Pyricularia oryzae

Phytopathology Research
CRISPR/Cas9 technology has been widely adopted for genome editing in a wide range of organisms, including many fungi. Pyricularia oryzae is a filamentous fungal pathogen that causes the devastating rice blast disease.

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 ...

Population structure and pathogenicity tests of Pyricularia oryzae on wild and cultivated rice in Mali

Plant Pathology
Blast is a devastating disease of rice caused by the fungus Pyricularia oryzae. The role of infected straw and seed as sources of primary inoculum in blast disease epidemics is well known. The role of alternative hosts is yet to be confirmed. The current

Intelligent recognition algorithm for rice diseases in farmland based on multileaf segmentation

Agronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Timely and accurate identification of specific types and development trends of rice (Oryza sativa L.) diseases in farmland is a critical prerequisite for implementing scientific control measures and reducing yield losses. Aiming at the problem of low recognition accuracy for rice diseases in farmland under natural lighting conditions, this ...

Effect of Light on Sporulation of Pyricularia oryzae Cavara

Japanese Journal of Phytopathology, 1970
Spore production of Pyricularia oryzae was relatively abundant on rice straw decoction plus V-8 juice agar (R+V-8), rice straw decoction agar (R), yeast starch agar (Y) and V-8 juice agar (V-8), but it was poor on oat meal agar (O) and potato decoction agar (P), in 7 days culture at 27°C in darkness.The spore production of the fungus on these media in ...

Evaluation of chitinase production ability to antagonize Pyricularia Oryzae of bacteria and actinomycete strains isolated from rice root soil in Kien Giang Province

Tạp chí Khoa học Đại học Mở Thành phố Hồ Chí Minh - Kỹ thuật và Công nghệ
The fungus Pyricularia oryzae is one of the agents causing rice blast disease. The mechanism of the infection is directing penetration through the plasma membrane, secreting cytotoxins, and forming infectious cells specialized for causing disease in rice
