Indole-3-acetic acid (IAA, 3-IAA) is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists. [1] IAA is a derivative of indole, containing a carboxymethyl substituent. It is a colorless solid that is soluble in polar organic ...
The 3 substrates of this enzyme are (indol-3-yl)acetaldehyde, H 2 O, and O 2, whereas its two products are (indol-3-yl)acetate and H 2 O 2. This enzyme belongs to the family of oxidoreductases , specifically those acting on the aldehyde or oxo group of donor with oxygen as acceptor.
The most important member of the auxin family is indole-3-acetic acid (IAA), [7] which generates the majority of auxin effects in intact plants, and is the most potent native auxin. And as native auxin, its equilibrium is controlled in many ways in plants, from synthesis, through possible conjugation to degradation of its molecules, always ...
Taphrina deformans is a fungus and plant pathogen, and a causal agent[s] of peach leaf curl. [1] Peach trees infected with T. deformans will experience leaf puckering and distortion, acquiring a characteristic downward and inward curl. Leaves will also undergo chlorosis, turning a pale green or yellow, and later show a red or purple tint. [2]

The systematic name of this enzyme class is (indol-3-yl)ethanol:NADP + oxidoreductase. Other names in common use include indoleacetaldehyde (reduced nicotinamide adenine dinucleotide, phosphate) reductase, indole-3-acetaldehyde reductase (NADPH), and indole-3-ethanol:NADP + oxidoreductase. This enzyme participates in tryptophan metabolism.
Indole is an organic compound with the formula C 6 H 4 CCNH 3. Indole is classified as an aromatic heterocycle. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered pyrrole ring. Indoles are derivatives of indole where one or more of the hydrogen atoms have been replaced by substituent groups.
It is a member of the class of compounds known as auxins and a chlorinated analogue of the more common indole-3-acetic acid (IAA) auxin. 4-Cl-IAA is found in the seeds of a variety of plants, particularly legumes such as peas and broad beans.
