Auxin Biosynthesis and Catabolism
Auxin concentrations in plants are tightly regulated through both biosynthesis and degradation. In the past few years, much progress was made in the area of auxin metabolism. Genetic and biochemical studies in Arabidopsis unequivocally established a complete tryptophan (Trp)-dependent two-step auxin biosynthesis pathway in which Trp is first converted into indole-3-pyruvate (IPA) by the TAA fam...
متن کاملAuxin Biosynthesis and Metabolism
Charles Darwin cited the 1871 I'h.D. thesis of Theophil Ciesielski when he postulated in 1880 that a "transmitted influence" present in the tip of plant shoots was responsible for gravitropism. Both Darwin and Ciesielski had realized that the influence was affecting growth differentially. This influence was given the name auxin more than 50 years later and subsequently any compound that promote...
متن کاملAuxin biosynthesis in maize kernels.
Auxin biosynthesis was analyzed in a maize (Zea mays) kernel culture system in which the seeds develop under physiological conditions similar to the in vivo situation. This system was modified for precursor feeding experiments. Tryptophan (Trp) is efficiently incorporated into indole-3-acetic acid (IAA) with retention of the 3, 3' bond. Conversion of Trp to IAA is not competed by indole. Labeli...
متن کاملAuxin biosynthesis and storage forms.
The plant hormone auxin drives plant growth and morphogenesis. The levels and distribution of the active auxin indole-3-acetic acid (IAA) are tightly controlled through synthesis, inactivation, and transport. Many auxin precursors and modified auxin forms, used to regulate auxin homeostasis, have been identified; however, very little is known about the integration of multiple auxin biosynthesis...
متن کاملNew Insights into Auxin Biosynthesis
It is well known that auxins, primarily indole-3-acetic acid (IAA), exert control over many important developmental processes in plants, including cell division and cell expansion, vascular tissue differentiation, root initiation, apical dominance, gravitropic and phototropic responses, flowering, fruit ripening, leaf senescence, and abscission of leaves and fruit. Despite the wealth of knowled...
