Chemical compounds that regulate plant growth and development Plant hormone (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, from embryogenesis,[1] the regulation of organ size, pathogen defense,[2][3] stress tolerance[4][5] and through to reproductive development.[6] Unlike in animals (in which hormone production is restricted to specialized glands) each plant cell is capable of producing hormones.[7][8] Went and Thimann coined the term "phytohormone" and used it in the title of their 1937 book.[9] Phytohormones occur across the plant kingdom, and even in algae, where they have similar functions to those seen in higher plants.[10] Some phytohormones also occur in microorganisms, such as unicellular fungi and bacteria, however in these cases they do not play a hormonal role and can better be regarded as secondary metabolites.[11] The word hormone is derived from Greek, meaning set in motion

Growth hormone | Definition, Function, Deficiency, & Excess
Summary growth hormone (GH), also called somatotropin or human growth hormone, peptide hormone secreted by the anterior lobe of the pituitary gland.

Growth Hormones Fed to Beef Cattle Damage Human Health
Almost all beef cattle entering feedlots in the United States are given hormone implants to promote faster growth. The first product used for this purpose DES (diethylstilbestrol) was approved for use in beef cattle in 1954.
