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
Molecular Biology of the Cell (textbook) understanding of cell biology and includes basic biochemistry, experimental methods for investigating cells, the properties common to most eukaryotic cells, the expression and transmission of genetic information, the internal organization of cells, and the behaviour of cells in multicellular organisms. "Molecular Biology of the Cell" has been described as “the most influential cell biology textbook of its time”. The sixth edition is dedicated to the memory of co-author Julian Lewis who died in early 2014. Molecular Biology of the Cell (textbook) Molecular Biology of the Cell is a cellular and molecular biology textbook published by Garland Science and currently authored
