Isolation of fungal homokaryotic lines from heterokaryotic transformants by sonic disruption of mycelia.
Fungal hyphae--and in some cases, spores--are multi-nucleate. During genetic transformation of these spores or mycelia, only one nucleus generally receives the transferred T-DNA generating heterokaryotic colonies. Characterization of genetic changes, such as the effects of gene disruption in the transformants, requires purified homokaryotic lines. Hyphal tip transfer has conventionally been use...
متن کاملUnresolved Problems in the Life Cycle of Truffles
The mating system and ploidy level of truffles, both mycorrhizal and sterile fruit-body hyphae are the subject of conflicting hypotheses. The current dogma concerning Ascomycetes, supported by recent studies on truffles, maintains that the mycorrhizing mycelium is homokaryotic and that the short-lived ascogenous heterokaryotic hyphae resulting from the fertilization process occur only in truffl...
متن کاملConidia of Heterobasidion annosum from Tsuga heterophylla forests in western Washington
HSIANG, T., EDMONDS, R. L., and DRIVER, C. H. 1989. Conidia of Heterobasidion annosurn from Tsuga heterophylla forests in western Washington. Can. J. Bot. 67: 1262-1266. Heterobasidion annosurn produces conidia abundantly in culture; however, since conidiophores are rare in nature, conidia are usually considered to have little or no role in dispersal. Heterokaryotic mycelia of H. annosurn produ...
متن کاملINTRINSIC FLUORESCENT COMPOUNDS IN ARMILLARIA MELLEA; HYPHAE AND RHIZOMORPH
The organic solvent extraction of Armillaria mellea showed different highly intrinsic fluorescent compounds either in rhizomorph or in hyphae (F , F , F , MF , MF and MF ). The characterization of ultraviolet and fluoro-spectrophotometry of these compounds has been exhibited. Thin layer chromatography and fluorescent spectrum of hyphae and rhizomorph indicated an additional compound (FH) ...
متن کاملA shift in nuclear state as the result of natural interspecific hybridization between two North American taxa of the basidiomycete complex Heterobasidion.
A natural first generation hybrid fungus shows interspecific heterozygosity. The nuclear condition of a rare natural hybrid between two taxa of the Heterobasidion complex is investigated. Heterobasidion species are known to be either homokaryotic (haploid) or heterokaryotic (n+n), but heterokaryons are made up of both homokaryotic and heterokaryotic sectors. The natural hybrid appears to be eit...
