- We also added the ta-siRNA that regulates Auxins as an example of ta-siRNAs found in plants.
- Understanding of the physiological mechanisms behind adventitious rooting has allowed some progress to be made in improving the rooting of cuttings by the application of synthetic auxins as rooting powders and by the use of selective basal wounding.
- The propagation of plants by cuttings of fully developed leaves, stems, or roots is performed by gardeners utilizing auxin as a rooting compound applied to the cut surface; the auxins are taken into the plant and promote root initiation.
- In addition to the information about gravitropsim which such auxin-transport or auxin-response mutants provide, they have been instrumental in identifying the mechanisms governing the transport and cellular action of auxin as well as its effects on growth.
- The mechanism responsible for polar auxin transport was first proposed in the seventies by Ruberry and Sheldrake and this visionary entirely relies on the properties of auxin as a weak acid, and the fact that the apoplastic pH is acidic while the cytosolic pH is neutral.
