Plant hormones and the control of physiological processes ...
Proper analysis of plant hormone levels occupied much journal space between 1960 and 1980. Debate centred on the fact that bioassays, as used in much research before 1960, did not provide a molecular identification of any chemical, an absolute prerequisite for quantification (Reeve & Crozier, 1980). This was not the only uncertainty with ...

· Background. Plant hormones are involved in many aspects of plant development and responses to biotic and abiotic stresses. The three major phytohormones responsible for mediating defense responses to pests and pathogens are jasmonic acid (JA), ethylene (ET), and salicylic acid (SA) [1–3].Recently, the participation of other hormones in defense signaling has become evident .
