Live-cell imaging of tubulin in the filamentous fungus Magnaporthe grisea treated with anti-microtubule and anti-microfilament agents.

Microtubule dynamics were examined in live cells of the fungal plant pathogen Magnaporthe grisea transformed for constitutive expression of a fusion protein containing enhanced yellow-fluorescent protein and a Neurospora crassa benomyl-resistant allele of beta-tubulin. Transformants retained their ability to differentiate appressoria and cause disease but remained sensitive to benomyl. Linear microtubule arrays and low-level cytoplasmic fluorescence were observed in vegetative hyphae, conidia, germ tubes, and developing appressoria.

Sequence analysis and functional characterization of the dialkylglycine decarboxylase gene DGD1 from Mycosphaerella graminicola.

Dialkylglycine decarboxylase is a pyridoxal phosphate-dependent enzyme in the aminotransferases class III group of enzymes. The enzyme is unique in terms of catalyzing both decarboxylation and transamination. Although the enzymatic activity is present in some bacteria and fungi, the biological role is unclear.

Efficient gene identification and targeted gene disruption in the wheat blotch fungus Mycosphaerella graminicola using TAGKO.

TAGKO ( transposon- arrayed gene knock out) is a highly efficient method for gene discovery and gene function assignment in the rice blast fungus Magnaporthe grisea. Here, we report the application of genome-wide TAGKO to the wheat blotch fungus Mycosphaerella graminicola, including the successful development of electroporation-based transformation for this fungus.
