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.
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.
Indole-3-acetic acid (IAA, 3-IAA) is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists. [1] IAA is a derivative of indole, containing a carboxymethyl substituent. It is a colorless solid that is soluble in polar organic ...
Micropropagation of plants is the process of using small samples of plants called explants and causing them to undergo growth of differentiated or undifferentiated cells. In connection with cytokinins like kinetin , auxins like IBA can be used to cause the formation of masses of undifferentiated cells called callus .
The model proposes that auxin, a plant growth hormone, is synthesized in the coleoptile tip, which senses light or gravity and will send the auxin down the appropriate side of the shoot. This causes asymmetric growth of one side of the plant. As a result, the plant shoot will begin to bend toward a light source or toward the surface. [3]
The U.S. Department of Agriculture will release approximately $20 million in funding for previously approved contracts that had been frozen by the Trump administration's push to overhaul the ...
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 ...
