Auxin: simply complicated

摘要: Auxin is a plant hormone involved in an extraordinarily broad variety of biological mechanisms. These range from basic cellular processes, such as endocytosis, cell polarity, and cycle control over localized responses elongation differential growth, to macroscopic phenomena embryogenesis, tissue patterning, de novo formation organs. Even though the history auxin research reaches back more than hundred years, we are still far comprehensive understanding how governs wide responses. Some answers this question may lie molecule itself. Naturally occurring auxin-like substances have been found they play roles specific developmental processes. The molecular mode action can be further explored by utilization synthetic molecules. A second area perception auxin, where know three seemingly independent receptors signalling systems, some better understood others, but each them probably distinct physiological Lastly, actively modified, metabolized, intracellularly compartmentalized, which great impact on its availability activity. In review, will give overview these rather recent emerging areas try formulate open questions. Without doubt, manifold facets biology not cease amaze us for long time come.
