Oplismenopsis najada new host of Pyricularia spp.

, 2022
Abstract Pyricularia spp is a fungal complex whose best known representative is Pyricularia oryzae. It also affects other weeds that grow alongside the rice culture, posing greater risk of contribute as primary inoculum for development, survival and dissemination of pathogen. During monitoring of species weeds near of rice culture in Corrientes

Phenolic Azo Dye Oxidation by Laccase from Pyricularia oryzae [PDF]

Applied and Environmental Microbiology, 1995
Laccase oxidation of phenolic azo dyes was examined with a commercially available laccase from Pyricularia oryzae as the model. Methyl-, methoxy-, chloro-, and nitro-substituted derivatives of 4-(4(prm1)-sulfophenylazo)-phenol were examined as substrates for this laccase. Only the substituents on the phenolic ring were changed. Among the dyes examined,

G Protein α Subunit Genes Control Growth, Development, and Pathogenicity of Magnaporthe grisea

Molecular Plant-Microbe Interactions, 1997
Three G protein α subunit genes have been cloned and characterized from Magnaporthe grisea: magA is very similar to CPG-2 of Cryphonectria parasitica; magB is virtually identical to CPG-1 of Cryphonectria parasitica, to gna1 of Neurospora crassa, and to ...

Exploring the Substitution of the C21‐OAc Moiety in [11]Cytochalasans: Synthesis and Evaluation of Fluorophore Conjugates

ChemBioChem, Volume 27, Issue 1, January 2026.
Via in silico docking of pyrichalasin H on G‐ and F‐actin, the C21‐OAc moiety is identified as a modifiable site tolerated for actin binding. Fluorescent [11]cytochalasan probes from pyrichalasin H and epoxycytochalasin C are obtained by selective C21‐OAc hydrolysis and acylation.

Characterisation of Magnaporthe oryzae isolates from rice in peninsular Malaysia.

Czech Journal of Genetics and Plant Breeding, 2016
The genus Pyricularia (anamorph)/Magnaporthe (teleomorph) includes important destructive pathogens causing blast disease on various species from the family Poaceae. Thirty-five Magnaporthe isolates were collected from diseased rice plants (variety MR219)

Cross‐Species Transfer of the Maize NAM‐ATAF1/2‐CUC2 Transcription Factor ZmNAC2 Confers Disease Resistance in Transgenic Rice Without a Yield Penalty

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
The maize ZmNAC2 gene, which encodes an NAM‐ATAF1/2‐CUC2 (NAC2) transcription factor, confers broad‐spectrum disease resistance (BSR) when introduced into rice without compromising yield. BSS, broad‐spectrum susceptibility. ABSTRACT Rice is a staple crop feeding over half of the global population, yet it faces severe yield losses due to devastating ...

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

Rice seedborne infection in southern Spain

Plant Protection Science, 2002
Rice (Oryza sativa) seeds were analysed to determine their potential transmission of pathogenic and saprophytic micro-organisms. In four and three hundred lots (stocks) of seeds, in 1998 and 1999 respectively, proceeding from mechanical drying sheds ...
