GANNIBAL P.B., KAZARTSEV I.A. (2013): Development of a PCR assay for amplification of mating-type loci of Alternaria spp. and related fungi. [population genetics, recombination, Ulocladium] Czech Mycology 65(1): 69-78 (published: 10th June, 2013)
abstract
A large number of ascomycete anamorphs including Alternaria spp. are considered asexual, but carry structurally conserved genes in a mating-type locus (MAT1) with two alternate idiomorphs, MAT1-1 and MAT1-2. Since the locus has lost its main function in many species, different directions of natural selection acting on the idiomorphs can be observed. Thus identification of mating types can be used in population biology studies. Also analysis of MAT1 locus sequences is needed for evolution and phylogeny reconstruction. Eighteen primers from previous works and this study were assessed for their ability to amplify MAT1 in 25 Alternaria and 7 Ulocladium, Embellisia and Alternariaster species. The most suitable primer pairs for 6 sections of Alternaria and several Ulocladium species were revealed.
MOSTAFA M.E., ZOHRI A.A., KOTBY R.S. (2001): Lipid, sterol and ergosterol accumulation in isolates of dematiaceous Hyphomycetes. [Lipid, sterol, ergosterol, dematiaceous hyphomycetes] Czech Mycology 53(2): 149-159 (published: 20th February, 2002)
abstract
Mycelial dry weight, lipid and sterol contents of fungi tested varied with fungalgenus, species and even with isolate of one species. Their dry mass fluctuated between lll.6±l0.7-457.0±41.5 mg/50 ml medium. Lipids, sterols and ergosterol accumulated by the isolates tested ranged from 4.52±0.5-29.04±2.76%, 1.23±0.16-10.63±l.24% and 0.43±0.057-7.13±0.695% of their dry mass, respectively. Cochliobolus spicifer isolate No. 35 was the highest lipid-producer while Ulocladium atrum No. 90 proved to be superior in the production of sterols and ergosterol. TLC technique and chemical analysis of lipid classes produced by U. atrium No. 90 revealed that the lipid fractions are composed of free sterols, free fatty acids, sterol esters, glycolipids, phospholipids and squalene.
ŘEPOVÁ A. (1986): The occurrence of microscopic fungi in air of the building of the Czechoslovak Acadeny of Sciences in České Budějovice. Česká Mykologie 40(1): 19-29 (published: 7th February, 1986)
abstract
68 species of microscopic fungi were isolated from the air in the building of the Czechoslovak Academy of Sciences in České Budějovice. 16 species were opportunistic, 12 allergenic, and 13 mycotoxin producers. 8 species were reported as air-borne fungi in literature.
