Mitsuyasu Hasebe focuses on Physcomitrella patens, Genetics, Gene, Botany and Sporophyte. Mitsuyasu Hasebe does research in Physcomitrella patens, focusing on Physcomitrella specifically. His Gene study frequently draws parallels with other fields, such as Cell biology. His work deals with themes such as Cell cortex, Cortical microtubule and Basal body, which intersect with Cell biology. His biological study spans a wide range of topics, including Auxin and Polyphyly. While the research belongs to areas of Sporophyte, he spends his time largely on the problem of Embryo, intersecting his research to questions surrounding Meristem, Flowering plant, Ploidy and Cell cycle.
