The objective of this study was to determine the mycotoxigenic potential of 12 Fusarium isolates (10 species), including six isolates (4 species) from sorghum. The species were: F. thapsinum, F. semitectum, F. proliferatum and F. chlamydosporum isola

Monosporascus cannonballus causes root rot and vine decline in muskmelons and watermelons. Wild types of this fungus often undergo degenerative changes that have been associated with yellow to brown pigmentation, hypovirulence, dsRNA infection, and d

Chain lengths and cyclization patterns of microbial polyketides are generally determined by polyketide synthases alone. Fungal polyketide melanins are often derived from a pentaketide 1,8-dihydroxynaphthalene, and pentaketide synthases are used for s

Sporothrix schenckii is a human pathogen that causes sporotrichosis, an important cutaneous mycosis with a worldwide distribution. It produces dark-brown conidia, which infect the host. We found that S. schenckii synthesizes melanin via the 1,8-dihyd

Fusarium equiseti and F. pallidoroseum are frequently reported as secondary colonizers of plant tissues. In this study they were isolated from the embryos of weathered cottonseed. Most isolates tested produced equisetin, an antibiotic, when grown on

Aspergillus fumigatus , an important opportunistic pathogen which commonly affects neutropenic patients, produces conidia with a bluish-green color. We identified a gene, alb1 , which is required for conidial pigmentation. The alb1 gene encodes a put

Two isolates of Aspergillus flavus were grown in shake cultures for 4 days at 30°C with 0 to 8 μg/ml of 2,3,4,5,6-pentachlorobenzyl alcohol (PCBA) or phthalide and 0 to 30 μg/ml of pyroquilon. The three compounds significantly inhibited the accumu

Nine compounds that inhibit 1,8-dihydroxynaphthalene (DHN)-melanin biosynthesis in Pyricularia oryzae were used to study their effect on pigment production in conidial walls of 11 Penicillium and 5 Aspergillus species. Conidial pigmentation in all of

A unique biotype of the Fusarium wilt pathogen, Fusarium oxysporum Schlecht. f.sp. vasinfectum (Atk) Sny. & Hans., found in Australia in 1993 is favored by neutral or alkaline heavy soils and does not require plant parasitic nematodes to cause diseas

Fusarium oxysporum is a fungal pathogen that attacks many important plants. Uniquely pathogenic strains of F. oxysporum f. sp. vasinfectum were inadvertently imported into the United States on live cottonseed for dairy cattle feed. These strains prod
