Auxin induces shoot apical dominance; the axillary buds are inhibited by auxin, as a high concentration of auxin directly stimulates ethylene synthesis in axillary buds, causing inhibition of their growth and potentiation of apical dominance. When the apex of the plant is removed, the inhibitory effect is removed and the growth of lateral buds ...
The impact of auxin on PIN polarity has been a subject of interest for many years, with various models suggesting that auxin's feedback occurs through PIN membrane cycling dynamics. However, recent advancements have challenged this hypothesis, with both natural and synthetic auxins promoting PIN2 endocytosis at low concentrations.
On exposure to sunlight, auxin in the banana migrates from the sunlight side to the shaded side. Since auxin is a powerful plant growth hormone, the increased concentration promotes cell division and causes the plant cells on the shaded side to grow. [13] This asymmetrical distribution of auxin is responsible for the upward curvature of the banana.
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 grafting, auxin promotes callus tissue formation, which joins the surfaces of the graft together. In ...
The apical bud produces a plant hormone, auxin , that inhibits growth of the lateral buds further down on the stem towards the axillary bud. Auxin is predominantly produced in the growing shoot apex and is transported throughout the plant via the phloem and diffuses into lateral buds which prevents elongation. [ 2 ]

Polar auxin transport (PAT) is directional and active flow of auxin molecules through the plant tissues. The flow of auxin molecules through the neighboring cells is driven by carriers (type of membrane transport protein) in the cell-to-cell fashion (from one cell to other cell and then to the next one) and the direction of the flow is determined by the localization of the carriers on the ...
Popular treatments that are available to help your hair grow faster include procedures like platelet-rich plasma, according to Marisa Garshick, M.D., F.A.A.D., board-certified dermatologist in NYC ...
