Molecular characterization of an endopolygalacturonase from Fusarium oxysporum expressed during early stages of infection

Article Abstract:

Researchers describe a 35kDa endopolygalacturonase from Fusarium oxysporum that is produced in tomato roots during the early stage of infection. However, inactivation of the enzyme does not affect the organism's virulence.

Detoxification of corn antimicrobial compounds as the basis for isolating Fusarium verticillioides and some other Fusarium species from corn

Article Abstract:

Researchers have incorporated natural antimicrobial compounds produced by corn into a growth medium for isolating Fusarium species from corn. Many Fusarium species are resistant to the compounds, whereas other fungi are not. Therefore, the medium could isolate Fusarium species while suppressing the growth of other fungi.

Endopolygalacturonase PG1 in different formae speciales of Fusarium oxysporum

Article Abstract:

The study compared a dozen Fusarium oxysporum isolates from seven different formae speciales to ascertain the diversity and occurrence of polygalacturonase 1 (PG1) and the species' corresponding gene. Two isolates were found to be PG1-deficient. In most of the other isolates, the pg1 locus was observed to be highly conserved in structure. No correlation was found between PG1 production by Fusarium oxysporum f. sp. melonis isolates and virulence for muskmelon.
