The effect of the low temperature (4 ºC) on the orga-nization of actin filaments (microfilaments) of cells of different growth zones of the root of Arabidopsis thaliana (L.) have been studied. It was found that cold treatment inhibits growth of the main root and gives its morphology, causing a large number of deformed (ectopic) root hairs in the zone of differentiation. The temporal relationship of the disorientation and the organization of actin filaments and the detected changes of growth and morphology of roots under conditions of cold factor is shown. It has been found that the most sensitive to the cold are actin filaments of root hairs, meristematic cells, cells of elongation zone, and all epidermal cells of the root zones of A. thaliana.
研究了低温（4℃）对拟南芥根不同生长区细胞肌动蛋白丝（微丝）组织的影响。发现冷处理会抑制主根生长并改变其形态，在分化区产生大量畸形（异位）根毛。展示了肌动蛋白丝的解取向与组织以及在冷因子条件下检测到的根生长和形态变化之间的时间关系。已发现拟南芥根区的根毛、分生细胞、伸长区细胞和所有表皮细胞的肌动蛋白丝对寒冷最为敏感。
