Auxin 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 کاملArabidopsis IAR4 modulates auxin response by regulating auxin homeostasis.
In a screen for enhancers of tir1-1 auxin resistance, we identified two novel alleles of the putative mitochondrial pyruvate dehydrogenase E1alpha-subunit, IAA-Alanine Resistant4 (IAR4). In addition to enhancing the auxin response defects of tir1-1, iar4 single mutants exhibit numerous auxin-related phenotypes including auxin-resistant root growth and reduced lateral root development, as well a...
متن کاملPlant Heat Adaptation: priming in response to heat stress.
Abiotic stress is a major threat to crop yield stability. Plants can be primed by heat stress, which enables them to subsequently survive temperatures that are lethal to a plant in the naïve state. This is a rapid response that has been known for many years and that is highly conserved across kingdoms. Interestingly, recent studies in Arabidopsis and rice show that this thermo-priming lasts for...
متن کاملA Mutation Altering Auxin Homeostasis and Plant Morphology in Arabidopsis.
Many aspects of plant development are associated with changing concentrations of the phytohormone auxin. Several stages of root formation exhibit extreme sensitivities to exogenous auxin and are correlated with shifts in endogenous auxin concentration. In an effort to elucidate mechanisms regulating development of adventitious roots, an ethyl methanesulfonate-mutagenized M2 population of Arabid...
