摘要：
Rare earth elements (REEs) in the environment enter the plant cells by initiating the endocytosis of plant leaf cells. But under natural condition, plants are mainly in contact with exogenous REEs via the roots. Here, we selected lanthanum ion [La(III)], a REE with high accumulation in the environment, and the model plant Arabidopsis thaliana to characterize effects of REEs on endocytosis in root cells, and revealed effect mechanisms from the perspective of cellular and molecular biology. Results indicated that La(III) enhanced the endocytosis of root cells and this enhancement depended on the doses of La(III) as follows: high dose (160 μmnol•L-1)>middle dose (80 μmnol•L-1)>low dose (30 μmnol•L-1) (12 h); middle dose (80 μmnol•L-1)>high dose (160 μmnol•L-1)>low dose (30 μmnol•L-1) (24 h). Except that the expression level of genes coding adapter protein 2 (AP2) decreased after 160 μmnol•L-1 La(III) treatment (24 h), the expression levels of genes coding AP2 and clathrin were all increased after other treatments. In summary, La(III) enhances endocytosis in root cells of Arabidopsis thaliana via up-regulating the expression level of genes encoding AP2 and clathrin AP2 serves as aptamer. © 2019, Editorial Office of Journal of the Chinese Society of Rare Earths.
