| 摘 要： | INTRODUCTION Cytokinins play a major role in many differentdevelopmental and physiological plant processes,such as cell division, regulation of root and shootgrowth and branching, chloroplast development,leaf senescence, stress response and pathogen re-sistance (Mok and Mok, 2001). Significant ad-vances have been achieved in our understanding ofcytokinin signaling, providing important insightsinto the molecular partners involved (Hutchisonand Kieber, 2002; Sheen, 2002). It had been…

| Abstract: | AtCRE1 is known to be a cytokinin receptor in Arabidopsis. The AtCRE1 protein contains CHASE domain at the N-terminal part, followed by a transmitter (histidine kinase) domain and two receiver domains. The N-terminal CHASE domain of AtCRE1 contains putative recognition sites for cytokinin. Five CHASE domains containing proteins were found in rice, OsCRL1a, OsCRL1b, OsCRL2, OsCRL3, and OsCRL4. OsCRL1a, OsCRL1b, OsCRL2 and OsCRL3 contain the four domains existing in CRE1, whereas OsCRL4 only contains the CHASE domain and a putative Ser/Thr protein kinase domain. The authors cloned the encoding gene OsCRL4 and found that it represents a new member of the cytokinin receptor protein in rice. |
