Plant hormones are specific types of compounds or peptides that function at a trace amount to coordinately regulate plant growth, development, and responses to biotic and abiotic signals throughout the life cycle of all plants ranging from lower to higher species. Besides the five classical plant hormones (auxins, gibberellins, cytokinins, ethylene and abscisic acid) that had been defined by the 1930’s, a growing number of compounds with hormonal functions are being discovered. Multidisciplinary studies, implemented with innovative technologies, have greatly advanced our knowledge about the roles and underlying mechanisms of plant hormones in controlling various aspects of crop traits. This research topic will highlight current knowledge and perspectives about hormonal control of important agronomic traits, such as crop architecture, grain size, nutrient uptake, symbiosis, and responses to abiotic stresses such as flooding, heat, and drought.
