Unicellular algae are the predominant microbial mat-forming phototrophs in the extreme environments of acidic geothermal springs. The ecology of these algae is not well known because concepts of species composition are inferred from cultivated isolat

All plants studied in natural ecosystemsare symbiotic with fungi that either resideentirely (endophytes) or partially(mycorrhizae) within plants. Thesesymbioses appear to adapt to biotic andabiotic stresses and may be responsible forthe survival of b

Gaeumannomyces graminis var. tritici is the aetiologic agent of take-all disease of wheat and barley. Heavily-melanized variants of a lightly pigmented, virulent wild-type strain were isolated and characterized. These variants were phenotypically sim

Recently we cloned and characterized three laccase genes from Gaeumannomyces graminis var. tritici, an important pathogen of wheat. Here we report cloning and characterization of two laccase genes from G. graminis var. graminis, a weak pathogen of ri

The effect of osmotic stress on mycelial growth was determined for melanized and nonmela- nized strains of Gaeumannomyces graminis var. tritici and var. graminis using a minimal salts medium, both in liquid and solid form. The osmotica used were KCl

Melanins are complex black polymers of resonance stabilized cyclic subunits (including in- doles, phenols, hydroxynaphthalenes) and are noto- riously intractable to chemical analysis. Cell walls of numerous fungi are melanized, rendering many spores,

In a previous study, we demonstrated that Suillus granulatus exhibits positive growth responses to added litter. From this, we hypothesized that this positive growth response (increased number of EM root tips) would be accompanied by increased activi

We purified a secreted fungal laccase from filtrates of Gaeumannomyces graminis var. tritici cultures induced with copper and xylidine. The active protein had an apparent molecular mass of 190 kDa and yielded subunits with molecular masses of 60 kDa

Gaeumannomyces graminis var. graminis produces 1,8-dihydroxynaphthalene (DHN) melanin in its hyphal and hyphopodial cell walls. We isolated G. graminis mutants that were affected in their melanin biosynthesis. One was unable to synthesize DHN-melanin
