Abstract:
Phytohormones are key signaling molecules that coordinate plant growth and development through a range of complex interactions. Since the vast majority of plant responses to given stimuli result, amongst other factors, from a crosstalk between hormones, simultaneous analysis of multiple hormones is vital to improve our understanding of these interactions. This chapter describes a sensitive, reliable, and inexpensive method for quantification of multiple phytohormones by gas chromatography-mass spectrometry (GC-MS).
