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

Candidates are selected based on a competitive project proposal and reference letters. The award scheme provides opportunity to work on a specified project in a different laboratory in a foreign country. It is associated with the journals "Biochemistry and Molecular Biology Education" (formerly "Biochemical Education"), "BioEssays", "BioFactors", "Biotechnology and Applied Biochemistry", "IUBMB Life", "Molecular Aspects of Medicine" and "Trends in Biochemical Sciences".
