Plant Development: Auxin in Loops
Concentration gradients of the hormone auxin are associated with various patterning events in plants. Recent work has refined our picture of the complex and dynamic system of auxin transport underlying the formation of these gradients.
متن کاملAuxin metabolism and homeostasis during plant development.
Auxin plays important roles during the entire life span of a plant. This small organic acid influences cell division, cell elongation and cell differentiation, and has great impact on the final shape and function of cells and tissues in all higher plants. Auxin metabolism is not well understood but recent discoveries, reviewed here, have started to shed light on the processes that regulate the ...
متن کاملMicroRNAs Regulate Auxin Homeostasis and Plant Development
The phytohormone auxin (principally indole-3-acetic acid [IAA]) is a key regulator of cell expansion and division that plays numerous roles in plant growth and development, including stem elongation, phototropic and gravitropic responses, apical dominance, and lateral and adventitious root formation. Auxin can stimulate or inhibit cell growth depending on its concentration and location within t...
متن کاملAuxin transport routes in plant development.
The differential distribution of the plant signaling molecule auxin is required for many aspects of plant development. Local auxin maxima and gradients arise as a result of local auxin metabolism and, predominantly, from directional cell-to-cell transport. In this primer, we discuss how the coordinated activity of several auxin influx and efflux systems, which transport auxin across the plasma ...
متن کاملAuxin receptors and plant development: a new signaling paradigm.
The plant hormone auxin, in particular indole-3-acetic acid (IAA), is a key regulator of virtually every aspect of plant growth and development. Auxin regulates transcription by rapidly modulating levels of Aux/IAA proteins throughout development. Recent studies demonstrate that auxin perception occurs through a novel mechanism. Auxin binds to TIR1, the F-box subunit of the ubiquitin ligase com...
