Plant hormones are naturally occurring small molecule compounds that play an important role in the normal functioning of the plant. It is present in very low concentrations in plants and regulate plant development, growth, longevity and reproductive processes. Based on their action, plant hormones are categorized into two categories, Plant Growth Promoters & Plant Growth Inhibitors. List of plant hormones include auxins, abscisic acid (ABA), gibberellins (GA), Cytokinin (CK), ethylene (ET), salicylic acid (SA), jasmonate (JA), peptides and brassinosteroids (BR) have been found in a broad spectrum of microalgal lineages. These hormones carry wide applications in stress resistance, pathogen defence, enriching soil nutrient content. Besides plants, these hormones are widely found in various algal taxa in concentrations comparable with their content in higher plants. This can be used as growth regulators for crops growth and development. These hormones from algae are determined using reverse-phase liquid chromatography - tandem mass spectrometry with multiple reaction monitoring. Their characterization methods, sources, types and usable synthetic hormones were reviewed in this article.
