Ethylene and the regulation of plant development

Ethylene for all the simplicity of its structure (C 2 H 4) regulates many aspects of plant growth and development [] The phrase 'growth and development' may be one of the most commonly used scientific phrases (a Google search turns up over 17 million hits) but for our purposes it is worthwhile to disengage the terms 'growth' and 'development' from each other
