A new antifungal antibiotic, YM-202204 (1), was found in the culture broth of marine fungus Phoma sp. Q60596. The structure of 1 was determined by several spectroscopic experiments as a new lactone compound. This antibiotic exhibited potent antifungal activities against Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus, and also inhibited glycosyl-phosphatidyl-inositol (GPI)-a...

Seven seed borne fungi were isolated from sugar beet seeds viz. Alternaria alternata, Helminthosporium sp., Rhizopus stolonifer, Epicoccum sp., Rhizoctonia solani, Phoma betae and Fusarium oxysporium f. sp. betae. The last three fungi were found internal, while the others were external on seed surface. The internal fungi caused root-rot disease to sugar beet plants. Tre11tment of seeds with eac...

Ascochyta and Phoma are fungal genera containing several important plant pathogenic species. These genera are morphologically similar, and recent molecular studies performed to unravel their phylogeny have resulted in the establishment of several new genera within the newly erected Didymellaceae family. An analysis of the structure of fungal mating-type genes can contribute to a better understa...

Through our screening for novel antifungal compounds, YM-215343 was found in the culture extract of Phoma sp. QN04621. The structure of YM-215343 was determined by several spectroscopic experiments as a novel compound closely related to apiosporamide and fischerin. YM-215343 exhibited antifungal activity against the pathogenic fungi, Candida albicans, Cryptococcus neoformans and Aspergillus fum...

The taxonomy of the coelomycetes has undergone dramatic changes in recent years, but remains controversial due to the high number of taxa involved, their poor morphological differentiation, the rare occurrence of the sexual morphs, and rapid loss of fertility in vitro. In the present study, we revisited the families Cucurbitariaceae and Didymellaceae (Pleosporales, Dothideomycetes), which inclu...

Finger millet is an ancient African cereal crop, domesticated 7000 years ago in Ethiopia, reaching India at 3000 BC. Finger millet is reported to be resistant to various fungal pathogens including Fusarium sp. We hypothesized that finger millet may host beneficial endophytes (plant-colonizing microbes) that contribute to the antifungal activity. Here we report the first isolation of endophyte(s...
