摘要
蓝氏贾第鞭毛虫具有明显的2个细胞核,典型的核膜结构,复杂的细胞骨架系统,并以有丝分裂作为其主要繁殖方式,但在分裂过程中核膜始终不解体,分裂方式为半开放式,加之细胞核的体积微小,细胞分裂速度较快,在细胞分裂过程中能否形成凝集的典型中期染色体,以及染色体的数目、形态等问题尚不明了,成为近年来国内外学者关注的焦点。本文从核分裂和胞质分裂两方面将蓝氏贾第鞭毛虫滋养体的有丝分裂过程进行了综述。
Giardia lamblia has two obvious nuclei,a typical nuclear membrane structure,and a complex cytoskeletal system and reproduces mainly by way of mitosis,but the nuclear membrane does not fully disintegrate during the division process,i.e.semi-open mitosis.Although Giardia lamblia has a very small nucleus and relatively rapid rate of cell division,whether or not it can form typical aggregated metaphase chromosomes and the number and shape of those chromosomes are not yet clear.Mitosis in Giardia lamblia has recently garnered attention at home and abroad.This paper summarizes the process of mitosis in terms of both karyokinesis and cytokinesis in Giardia trophozoites.
