Signal perception and transmission of the plant hormone ethylene are mediated by a family of receptor histidine kinases located at the Golgi-ER network. Similar to bacterial and other plant receptor kinases, these receptors work as dimers or higher molecular weight oligomers at the membrane. Sequence analysis and functional studies of different isoforms suggest that the ethylene receptor ...

Protocol: An updated integrated methodology for analysis ...

Ethylene concentrations are quantified by GC. Calibration is done by defining the linear relation between peak area and the known ethylene concentration (ppm) of at least three different calibration concentrations covering the entire detector response range. Before each set of measurements the calibration curve needs to be validated again.
