Determination strategies of phytohormones: recent advances

Abstract

Phytohormones are key regulators in various physiological processes of plant growth and development. To better understand their regulatory actions, fast, sensitive and accurate methods for phytohormone analysis are critically required, and great efforts have been invested in this field. In this review, recent advances and developments in phytohormone determination strategies are presented, in terms of sample preparation and analytical approaches. Many types of analytical techniques are involved, including chromatography, mass spectrometry, immunoassay and others. Some challenges and prospects are also discussed.
