Crozier (mycology) Crozier (mycology) A crozier is an anatomical feature of many fungi in the phylum Ascomycota that form at the base of asci and look like hook-topped shepherd’s staffs or stylized religious crosiers. During the ascus initial formation the crozier helps to maintain a dikaryotic state in the ascus initial and its side branch that will continue the spreading growth of the ascogenous hyphae in Ascomycota fruitbodies. The tips of developing asci on these ascogenous hyphae curl over. One haploid nucleus migrates into the curved tip while the other compatible haploid nucleus remains in the penultimate space below the hook. The
Biology of the Cell Biology of the Cell Biology of the Cell is a peer-reviewed scientific journal in the field of cell biology, cell physiology, and molecular biology of animal and plant cells, microorganisms and protists. Topics covered include development, neurobiology, and immunology, as well as theoretical or biophysical modelling. The journal is currently published monthly by Wiley-Blackwell on behalf of the Société Française des Microscopies and the Société de Biologie Cellulaire de France. The journal first appeared in 1962 and was originally titled "Journal de Microscopie" (1962–1974). In 1975 the journal was retitled "Journal de Microscopie et de Biologie Cellulaire" (; 1975–1976). It
