The Risk of Wheat Blast in Rice–Wheat Co-Planting Regions in China: MoO Strains of Pyricularia oryzae Cause Typical Symptom and Host Reaction on Both Wheat Leaves and Spikes

Phytopathology, 2021
Triticum pathotype (MoT) of Magnaporthe oryzae (syn. Pyricularia oryzae) causes wheat blast, which has recently spread to Asia. To assess the potential risk of wheat blast in rice-wheat growing regions, we investigated the pathogenicity of 14 isolates of

<i>Pyricularia pennisetigena and Pyricularia oryzae</i> isolates from Paraguay's wheat-growing regions and the impact on wheat. [PDF]

Curr Res Microb Sci
The Pyricularia genus includes species causing blast disease in monocots, posing significant challenges for disease management due to their ability to infect multiple hosts. This study aimed to identify the pathogenicity and species identity of Pyricularia isolates from 11 plant species in wheat-growing regions of Paraguay and assess their capacity to ...

Strigolactone deficiency induces jasmonate, sugar and flavonoid phytoalexin accumulation enhancing rice defense against the blast fungus Pyricularia oryzae.

New Phytologist, 2023
Strigolactones (SLs) are carotenoid-derived phytohormones that regulate plant growth and development. While root-secreted SLs are well-known to facilitate plant symbiosis with beneficial microbes, the role of SLs in plant interactions with pathogenic ...

Specific detection of Pyricularia oryzae pathotype Triticum using qPCR and LAMP methods

Journal of General Plant Pathology, 2023
Wheat blast is an important disease that affects cross-border food security. The causal pathogen, Pyricularia oryzae (syn. Magnaporthe oryzae) Triticum pathotype (MoT), forms a phylogenetic group distinct from the other P. oryzae pathotypes pathogenic on

Morphological and Physiological Development of Pyricularia oryzae Isolates from North-western Region of Sarawak on Different Media under Laboratory Conditions

Borneo Journal of Resource Science and Technology, 2023
Rice blast (causal agent: Pyricularia oryzae) is an important disease of rice in Sarawak. Understanding the pathogen’s morphological characteristics, genetic diversity and pathogenicity is important. Having a suitable medium for culturing and maintaining

Evolution and Regulation of a Large Effector Family of Pyricularia oryzae [PDF]

Molecular Plant-Microbe Interactions®, 2021
Plant pathogen effectors play important roles in parasitism, including countering plant immunity. However, investigations of the emergence and diversification of fungal effectors across host-adapted populations has been limited. We previously identified a gene encoding a suppressor of plant cell death in Pyricularia oryzae (syn.
