【摘要】 肌动蛋白在真核生物中广泛存在,由肌动蛋白参与形成的动态微丝骨架系统是细胞生命活动的基础。在植物细胞中,肌动蛋白由多基因家族编码,从而产生了多种肌动蛋白异型体。本文综述了拟南芥肌动蛋白异型体的分类、体内分布与功能,详细介绍了豌豆卷须肌动蛋白异型体的研究现状,并讨论了该领域的研究方向。更多还原

【Abstract】 Actin, the major component of the dynamic microfilament cytoskeleton system, exists in nearly all eukaryotic cells and plays essential roles in cellular activities. In plant cells, actins are encoded by multi-gene families, and many kinds of actin isoforms have been found. This paper summarizes the research in elucidating the classes, distribution and function in vivo of actin isoforms in Arabidopsis, introduces new research into actin isoforms of pea tendril and discusses the possible future research direction in this field.更多还原
