Occurrence, Function, and Biosynthesis of the Natural Auxin Phenylacetic Acid (PAA) in Plants
Auxins are a class of plant hormones playing crucial roles in a plant’s growth, development, and stress responses. Phenylacetic acid (PAA) is a phenylalanine-derived natural auxin found widely in plants.

Auxin Response Factors: output control in auxin biology [PDF]
Abstract The phytohormone auxin is involved in almost all developmental processes in land plants. Most, if not all, of these processes are mediated by changes in gene expression. Auxin acts on gene expression through a short nuclear pathway that converges upon the activation of a family of DNA-binding transcription ...

Although changes in root architecture in response to the environment can optimize mineral and water nutrient uptake, mechanisms regulating these changes are not well-understood.

Auxin-Induced Plasma Membrane Depolarization Is Regulated by Auxin Transport and Not by AUXIN BINDING PROTEIN1 [PDF]
Auxin is a molecule, which controls many aspects of plant development through both transcriptional and non-transcriptional signaling responses. AUXIN BINDING PROTEIN1 (ABP1) is a putative receptor for rapid non-transcriptional auxin-induced changes in plasma membrane depolarization and endocytosis rates.

Auxin and Cellular Elongation [PDF]
Auxin is a crucial growth regulator in plants. However, a comprehensive understanding of how auxin induces cell expansion is perplexing, because auxin acts in a concentration- and cell type-dependent manner. Consequently, it is desirable to focus on certain cell types to exemplify the underlying growth mechanisms.

During development of nodules and roots, the alfalfa early nodulin gene MsEnod12A is expressed adjacent to the meristem. Using transgenic alfalfa carrying a MsEnod12A promoter-gusA fusion, we investigated the regulation of MsEnod12A expression in mature ...

Auxin acts as a general co-ordinator of plant growth and development, transferring information over both long and short ranges. Auxin famously appears to be extraordinarily multi-functional, with different cells responding very differently to changes in auxin levels.

Indole-3-acetic acid (IAA or auxin) is essential throughout the life cycle of a plant. It controls diverse cellular processes, including gene expression. The hormone is perceived by a ubiquitin protein ligase (E3) and triggers the rapid destruction of repressors, called Aux/IAA proteins.

THE CONSERVATION OF SPECIES BELLEVALIA SARMATICA (GEORGI) WORONOV BY THE VITROCULTURE METHOD [PDF]
In vitro bulbification is a method by which bulb formation is stimulated and speeded up in the species that are propagated by bulbs and which need, in the conditions of a classicel culture, a longer period for the formation of flower-bearing bulbs.
