| double-stranded rna viruses in a mycocinogenic strain of cystofilobasidium infirmominiatum. | the viral particles (about 30 nm in diameter) that contain dsrnas (2.0 and 6.3 kbp) encapsidated by a coat of protein were detected in a mycocin-secreting strain of cystofilobasidium infirmominiatum isolated from plants in an oak forest (moscow region). the mycocin with a molecular mass above 15 kda is fungicidal (maximum activity at ph 4.5) and active mainly against some species of the cystofilobasidiales and filobasidiales ('cryptococcus aerius' clade). curing by incubation at elevated tempera ... | 2003 | 12702247 |
| mycocin production in cryptococcus aquaticus. | double-stranded rna viruses of about 35 nm in diameter were isolated from a mycocin-secreting strain of cryptococcus aquaticus. a derivative of this strain, lacking small dsrna, was non-mycocinogenic and sensitive to its own toxin. the killing pattern of this mycocin was restricted to some species of the cystofilobasidiales clade. despite the differences in genome size of dsrna viruses in mycocinogenic strains of cryptococcus aquaticus, cystofilobasidium sp. cbs 6569, cystofilobasidium bisporidi ... | 2004 | 15702390 |
| intermediates in the oxidative pathway from torulene to torularhodin in the red yeasts cystofilobasidium infirmominiatum and c. capitatum (heterobasidiomycetes, fungi). | two red cystofilobasidium spp. isolated from spring sap-flows of betula pendula were analysed for their carotenoid content. in cystofilobasidium infirmominiatum, three unusual pigments were detected and identified by structure elucidation as oxidised torulene derivatives. these included 16'-hydroxytorulene and torularhodinaldehyde, two carotenoids known so far only from chemical synthesis or as postulated biosynthetic intermediates en route to torularhodin. unprecedented formation of beta-apo-2' ... | 2007 | 17597170 |
| glycine betaine improves oxidative stress tolerance and biocontrol efficacy of the antagonistic yeast cystofilobasidium infirmominiatum. | the effect of h2o2-induced oxidative stress on the viability of the yeast antagonist, cystofilobasidium infirmominiatum, as well as the effect of exogenous glycine betaine (gb) on yeast viability under oxidative stress, was determined. gb treatment improved the tolerance of c. infirmominiatum to oxidative stress. compared to untreated control yeast cells, gb-treated cells showed less accumulation of reactive oxygen species (ros) and a lower level of protein oxidation in response to oxidative str ... | 2011 | 21353322 |
