Auxin thesis

The auxin-induced growth reaction of the avena coleoptile has been treated by methods of classical enzyme kinetics the kinetic treatment makes it possible to characterize the growth promoting activity of an auxin by two parameters, k[subscript s] and v[subscript max]. Occurring auxin, can affect well-defined steps in development iaa is made either by de novo syn- thesis and the amount of free iaa in wild-type seedlings. This thesis investigates the function of several auxin-regulated genes that control different aspects of root growth and development it is important to maintain an appropriate auxin level in plant tissues by regulating auxin biosynthesis, transportation, conjugation and degradation pathways. Auxin action and cell elongation : a rational approach : a thesis presented in partial fulfillment of the requirements for the degree of doctor of philosophy in plant physiology at massey university. Unlike the yucs that exist throughout the plant kingdom, the cyp79b family has so far only been identified in arabidopsis, brassica napus, and sinapis alba , suggesting that the yuc pathway is likely a universally used auxin biosynthesis pathway whereas iaa synthesis by the cyp79b family may have more specific roles in crucifers.

And biochemical mechanisms of auxin biosyn-thesis will have a great impact on defining the roles of auxin in plant development, un-derstanding auxin transport, and . Distribution and regulation of auxin in arabidopsis root cells the hormone auxin, the main focus of this thesis, has a vast influence on plant development the .

The results show that auxin promotes the enlargement of the individual cells particularly in the young cultures the cell volume is proportional to the logarithm of the auxin concentration in older cultures the matter is complicated by the shortage of another factor, presumably food. A thesis submitted in conformity with the requirements for the degree of master of science under altered auxin signaling conditions tatiana smirnova . Abstract microbial synthesis of the phytohormone auxin has been known for a long time this property is best documented for bacteria that interact with plants because bacterial auxin can cause interference with the many plant developmental processes regulated by auxin.

Auxin transport synthesis of iaa is not always site of action, so must be moved to other locations:. Inhibition of auxin movement from the shoot into the root inhibits lateral root development in auxin transport is required ms thesis wake forest university . Genetic and biochemical studies in arabidopsis unequiv-ocally established a complete tryptophan (trp)-dependent two-step auxin biosyn-thesis pathway in which trp is first converted into indole-3-pyruvate (ipa) by the taa family of aminotransferases and subsequently indole-3-acetic acid (iaa) is produced from ipa by the yuc family of flavin . The role of auxin and ethylene in adventitious root formation in arabidopsis and tomato by poornima sukumar this thesis research explored the.

Auxin regulation of cytokinin biosynthesis in arabidopsis thaliana: a factor of potential importance synthesis is a critical question for understanding the cross . Auxin-induced growth inhibition used in this thesis and dr nathan miller for developing the software to visualize it so beautifully this experience would have been impossible were it not for the funding that has. Auxins are a class of phytohormones involved in numerous thesis of antioxidants and the activity of basic antioxidant enzymes, and some of these enzymes are also .
