Hypoxylon cohaerens: Cytology of the ascus
Tóm tắt
The haploid chromosome number ofHypoxylon cohaerens apparently is 5, based on counts made at meiotic prophase and meiotic and mitotic metaphases. Newly formed ascospores are at first uninucleate, becoming binucleate following mitosis in the ascospore. Subsequently, one of the two nuclei disappears. Maturing ascospores are uninucleate.
