摘要
Cytokinins are N^6-substituted adenine derivatives that are involved in the regulation of numerous aspects of plant growth and development. These include the control of cell division, leaf senescence, apical dominance, sink^source relationship, vascular and embryonic development, and apical meristem activity （Kieber and Schaller, 2014）. In addition, there is increasing evidence for the function of cytokinins in abiotic stress responses （Zwack and Rashotte, 2015）.
