Molecular Structure of rDNA Repeat Unit inMagnaporthe grisea [PDF]
Bioscience, Biotechnology, and Biochemistry, 2000 The 8-kb repeat unit of M. grisea rRNA-encoding DNA (rDNA) was cloned as three subclones, pM50, pM21, and pM86. Nucleotide sequencing of these subclones uncovered the structure of an rDNA repeat unit similar to those of other ascomycetes. The intergenic spacer (IGS) of the rDNA cistron contained a repetitive (R) region, which was rich in two kinds of ...

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.

Pyricuol, a New Phytotoxin fromMagnaporthe grisea
Bioscience, Biotechnology, and Biochemistry, 1998 A new pyriculol-related phytotoxin, designated as pyricuol (1), was isolated from a liquid culture of Magnaporthe grisea, the causal fungus of rice blast disease, together with two known metabolites, pyriculol (2) and dihydropyriculol. Its structure was determined on the basis of physicochemical and spectroscopic data to be 2-(3-hydroxymethyl-1,4 ...

Transposon impala, a Novel Tool for Gene Tagging in the Rice Blast Fungus Magnaporthe grisea
Molecular Plant-Microbe Interactions, 2001 impala, a Tc1-mariner transposable element from Fusarium oxysporum, was introduced into the rice blast fungus Magnaporthe grisea to develop transposon-based insertional mutagenesis.

Legacy hexaconazole and tricyclazole residues hinder organic transition in paddy rice cultivation
Agricultural &Environmental Letters, Volume 11, Issue 2, December 2026.Hexaconazole and tricyclazole residues persisted in paddy soil throughout the three consecutive growing seasons after a single foliar application. These findings, combined with potential animal feed risks from contaminated rice straw, indicate that the current 2‐year organic transitional period is insufficient, necessitating extended conversion periods

Pest Management Science, Volume 82, Issue 8, Page 7510-7525, August 2026.Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.
