⭐ Core Definition: Frits Warmolt Went

Frits Warmolt Went (May 18, 1903 – May 1, 1990) was a Dutch biologist whose 1928 experiment demonstrated the existence of auxin in plants.

Went's father was the prominent Dutch botanist Friedrich August Ferdinand Christian Went. After graduating from the University of Utrecht, The Netherlands in 1927 with a dissertation on the effects of the plant hormone auxin, Went then worked as a plant pathologist in the research labs of the Royal Botanical Garden in Buitenzorg, Dutch East Indies (now Bogor, Indonesia) from 1927 to 1933. He then took a position at the California Institute of Technology (Caltech) in Pasadena, California, first researching plant hormones. His interest gradually shifted to environmental influences on plant growth. At Caltech, he was among the first to demonstrate the importance of hormones in plant growth and development. He played an important role in the development of synthetic plant hormones, which then became the basis of much of the agricultural chemical industry.

👉 Frits Warmolt Went in the context of Thimann

Kenneth Vivian Thimann (August 5, 1904 – January 15, 1997) was an English-American plant physiologist and microbiologist known for his studies of plant hormones, which were widely influential in agriculture and horticulture. He isolated and determined the structure of auxin, the first known plant hormone. He spent most of his early career (1935–1965) at Harvard University, and his later career (1965–1989) at the University of California, Santa Cruz. He is credited with identifying indole-3-acetic acid as an auxin.

Thimann was born in Ashford, England. He studied chemistry and biochemistry at Imperial College, University of London (earning a B.Sc. and a Ph.D.) and also received a diploma from the University of Graz. After several years teaching at the University of London, Thimann moved to the California Institute of Technology in 1930. In 1935, he joined the Biology department of Harvard University. He authored an influential book on plant hormones, Phytohormones, in 1937 (co-authored with F. W. Went). He was elected to the American Academy of Arts and Sciences in 1938. Thimann became director of Harvard's Biological Laboratories in 1946, a position he held until 1950. He was elected to the United States National Academy of Sciences in 1948. In 1955 he wrote The Life of Bacteria, an influential book on microbiology. He was elected to the American Philosophical Society in 1959. From 1962 until leaving Harvard in 1965, Thimann was the Higgins Professor of Biology.

Frits Warmolt Went in the context of Plant hormone

Plant hormones (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, including embryogenesis, the regulation of organ size, pathogen defense, stress tolerance and reproductive development. Unlike in animals (in which hormone production is restricted to specialized glands) each plant cell is capable of producing hormones. Went and Thimann coined the term "phytohormone" and used it in the title of their 1937 book.

Phytohormones occur across the plant kingdom, and even in algae, where they have similar functions to those seen in vascular plants ("higher plants"). 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.

Frits Warmolt Went in the context of Auxin

Auxins (plural of auxin /ˈɔːksɪn/) are a class of plant hormones (or plant-growth regulators) with some morphogen-like characteristics. Auxins play a cardinal role in coordination of many growth and behavioral processes in plant life cycles and are essential for plant body development. The Dutch biologist Frits Warmolt Went first described auxins and their role in plant growth in the 1920s.Kenneth V. Thimann became the first to isolate one of these phytohormones and to determine its chemical structure as indole-3-acetic acid (IAA). Went and Thimann co-authored a book on plant hormones, Phytohormones, in 1937.
