Purification and characterization of the head-activator receptor from a multi-headed mutant of Chlorohydra viridissima.

abstract：:One of the most intriguing plant defense reactions against herbivores is the emission of volatiles as potentially attractive signals for the natural enemies of the attacking species. Like many other low and high molecular weight chemical defenses, volatile production is under the control of the octadecanoid signalling...
