Auxin - Wikipedia
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.
Mechanisms regulating auxin action during fruit development
In this review, we summarize recent research that has started to elucidate the molecular mechanisms by which auxin is produced and transported in the fruit and to unravel the complexity of auxin signaling during fruit development.
The role of auxin during early berry development in grapevine …
Jun 14, 2021 · Auxin is a key phytohormone that modulates fruit formation in many fleshy fruits through the regulation of cell division and expansion.
Auxin export from proximal fruits drives arrest in temporally
May 25, 2020 · Complete fruit removal, or lack of fertile fruit-set, prevents timely inflorescence arrest in Arabidopsis, leading to a previous proposal that a cumulative fruit/seed-derived signal causes ...
Roles of Auxin in the Growth, Development, and Stress Tolerance …
Auxin signaling is tightly regulated during fruit set and fruit development. Many plant hormones regulate the complex process of ovary-to-fruit transformation, of which the regulation of auxin predominates.
Mechanism of fertilization-induced auxin synthesis in the ... - Nature
Jul 9, 2022 · The essential role of auxin in fruit induction is supported by genetic studies in plants such as Arabidopsis and tomato, where mutants with defects in auxin signaling develop virgin (or...
Phytohormones in fruit development and maturation - Fenn
Dec 4, 2020 · Auxin signaling and auxin–GA interaction are key elements influencing fruit growth, and these pathways rely on Aux/IAA, ARF, and GH3 activities. GH3.1 expression is elevated during cell division in apples to maintain free auxin levels, and MdARF106 is among a number of Malus ARFs predominant in fruit development (Devoghalaere et al ., 2012 ).
Auxin Begins to Give Up Its Secrets | Science - AAAS
Sep 1, 2006 · As a fruit forms, its seeds produce a plant hormone called auxin, prompting the fruit to grow and ripen. Without seeds—and without auxin—fruit stays shrunken on the stem. The wonders auxin works on strawberries and tomatoes are just the start.
Exogenous auxin regulates the growth and development of peach fruit …
For example, the application of auxin at the later stage of fruit development can promote peach fruit ripening and softening by inducing ethylene production [13, 36]. However, the molecular mechanisms and regulatory networks of auxin-induced fruit growth and development at the fruit expansion stage are still unclear.
Auxin: simply complicated | Journal of Experimental Botany
May 24, 2013 · Additionally, synthetic auxins are used as active molecules in commercial solutions for horticulture as they promote the initiation of adventitious roots and the synchronization of flowering and fruit set.
