Radiation effects and mitotic recombination in diploids of Aspergillus nidulans.
NTENSE gamma-radiation of conidia has been found to produce a very high I frequenc y of abnormal, sectoring colonies in heterozygous diploids of Aspergillus nidulans (=FER 1960). To obtain information about the nature of the radiation effects which cause the formation of colonies with many large segregant sectors, a detailed analysis of a relatively small number of such sectoring colonies has b...
متن کاملSexual diploids of Aspergillus nidulans do not form by random fusion of nuclei in the heterokaryon.
The sexual stage of Aspergillus (Emericella) nidulans consists of cleistothecia containing asci, each with eight ascospores. The fungus completes the sexual cycle in a homokaryotic or a heterokaryotic mycelium, respectively. The common assumption for the last 50 years was that different nuclear types are not distinguishable when sexual development is initiated. When cultured on a medium limited...
متن کاملIntersexual partial diploids of phycomyces.
Sexual interaction between strains of opposite sex in many fungi of the order Mucorales modifies hyphal morphology and increases the carotene content. The progeny of crosses of Phycomyces blakesleeanus usually include a small proportion of anomalous segregants that show these signs of sexual stimulation without a partner. We have analyzed the genetic constitution of such segregants from crosses...
متن کاملThe canonical equation of adaptive dynamics for Mendelian diploids and haplo-diploids.
One of the powerful tools of adaptive dynamics is its so-called canonical equation (CE), a differential equation describing how the prevailing trait vector changes over evolutionary time. The derivation of the CE is based on two simplifying assumptions, separation of population dynamical and mutational time scales and small mutational steps. (It may appear that these two conditions rarely go to...
متن کاملInstability of Aspergillus galactomannan in stored clinical samples.
We read with interest the recent paper by Wheat et al. (1) reporting on the long-term stability of Aspergillus galactomannan in bronchoalveolar lavage fluid (BALF) and serum specimens stored at 20°C. Their findings contrasted with previously published results from Johnson et al. (2), who had observed a significant loss of signal in serum— but not BALF—samples upon long-term storage. We here exp...
