PURIFICATION AND CHARACTERIZATION OF RECOMBINANT ETHYLENE RECEPTOR ETR1 FROM ARABIDOPSIS THALIANA

摘要

In plants the gaseous hormone ethylene regulates many aspects of growth and development, such as germination, ripening or leaf abscission. Furthermore, ethylene is also supposed to mediate a number of various stress signals as well as pathogen attack(Bleecker et al 2002). Signal perception and response to ethylene are mediated by a small family of integral membrane receptors including the ETR1 gene product. These receptor proteins show substantial ho-mology to bacterial and eukaryotic two-componentregulator proteins and contain an N-terminal transmembrane sensor domain, a catalytic transmitter domain including a histidine kinase domain and a C-terminal response regulator domain (Bleecker et al 2002).
