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.
Auxins (plural of auxin / ˈ ɔː k s ɪ n /) 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.
Plant physiologists have identified four different stages the plant goes through after the apex is removed (Stages I-IV). The four stages are referred to as lateral bud formation, "imposition of inhibition" (apical dominance), initiation of lateral bud outgrowth following decapitation, and; elongation and development of the lateral bud into a ...
Aldo Carl Leopold (December 18, 1919 – November 18, 2009) was an American academic and plant physiologist, son of Aldo Leopold, a noted ecologist. He is known for his research on soybeans which led to techniques allowing insulin to be dried and later processed into an inhalable insulin .
The mechanism of apical dominance is based on auxins, types of plant growth regulators. These are produced in the apical meristem and transported towards the roots in the cambium . If apical dominance is complete, they prevent any branches from forming as long as the apical meristem is active.
Within the 20-year timespan, many scientists have actively contributed to examining and reevaluating Hager's acid-growth hypothesis. Despite the accumulation of observations that evidently identify the final target of the auxin-induced action to be H +-ATPase, which excretes H + protons to the apoplast and take in K + ions through its rectifying K + channel in the following years, the ...
Kinetin is often used in plant tissue culture to induce callus formation (in conjunction with auxin) and regenerate shoot tissues from callus (with lower auxin concentration). For a long time, it was believed that kinetin was an artifact produced from the deoxyadenosine residues in DNA , which degraded when standing for long periods or when ...
The Amino Acid/Auxin Permease (AAAP) Family is a family of secondary carrier proteins, a member of the APC Superfamily that includes hundreds of proteins from plants, animals, fungi and lower eukaryotes.
