Research Progress in Bryophyte Sporogenesis
苔藓植物孢子发生的研究进展

Sporogenesis in bryophytes is a complex cytomorphogenetic process. It is characterized by precise nuclear and cytoplasmic divisions resulting in tetrads of haploid spores and the development of spore wall. The structure in cytoplasmic lobing, plastid and nuclear change, system of microtubules and the meiotic spindle, meiotic cytokinesis, spore wall development of bryophyte sporogenesis are introduced in this paper.
