Nodal explants of Phyla nodiflora (L.) Greene, were cultured on Murashige and Skoog (MS) medium supplemented with different combination and concentration of cytokinins and auxins for multiple shoots regeneration. The maximum numbers of shoots were found in MS medium supplemented with2.5 mgl-16-benzylaminopurine (BA) and 0.5 mgl-1 kinetin (KN). Elongated shoots were transferred to rooting ...

THE TITLE COMPOUND (SYSTEMATIC NAME 16-hydroxy-methyl-12-methoxy-ibogamine), C(21)H(28)N(2)O(2), was prepared by reaction of ibogaine with a formaldehyde-acetic acid solution (pH = 4). The crystal structure of this new product, belonging to the iboga indole family, is stabilized by an inter-molecular O-H⋯N hydrogen bond. The identity of the compound was confirmed by one- and two-dimensional NMR...

Using reversed-phase "high-performance" liquid chromatography with fluorescence detection, we separated and identified some naturally fluorescent compounds in uremic serum and hemodialysate from patients with chronic renal disease. Several of the naturally fluorescent compounds were identified as indole derivatives by co-chromatography with authentic standards. In one specific case, the identit...

The importance of growth substances in the normal development of plant tissues has suggested that, when present in. unusual amounts, they may be more or less directly responsible for atypical and pathological growth. Attention has been directed especially to such growths as crown gall caused by Phytomonas tumefaciens (Smith and Town.) Bergey et al. Beta-indole-acetic acid and substances related...

Advances made recently in the study of plant growth substances and their function in normal growth have raised the question of their possible role in atypical and pathological growth and specifically in the gall development induced by Phytomonas tumefaciens (Smith and Town.) Bergey et al. A suggestion of their presence was first given by the marked epinasty of leaf petioles in plants inoculated...

Abstract The fabrication of diodes using organic semiconductors as active materials has gained wide interest, and undergone significant progress in the past few decades. A naphthalimide-indole derivative (BNIA) was synthesized through bromination acenaphthene, subsequent oxidation, finally imidation with indole-3-acetic anhydride. molecular structure characterized NMR IR spectroscopy. BNIA disp...

1. The effects in the cow of intraruminal infusions of acetic acid, propionic acid or butyric acid on the secretion of the component fatty acids of the milk fat, and of these acids and of lactic acid on the composition of the blood plasma of the jugular vein, have been studied. 2. The infusion of acetic acid or butyric acid increased the yield of the C(4)-C(16) acids of milk fat but decreased t...

Arabidopsis (Arabidopsis thaliana) contains 15 genes encoding members of the pleiotropic drug resistance (PDR) family of ATP-binding cassette transporters. These proteins have been speculated to be involved in the detoxification of xenobiotics, however, little experimental support of this hypothesis has been obtained to date. Here we report our characterization of the Arabidopsis PDR9 gene. We ...

Partial hydrolysis of polygalacturonic acid with a purified alpha-1,4-endopolygalacturonase yielded oligogalacturonides and trace amounts of a series of modified oligogalacturonides. Three of the minor products were isolated and identified as oxidized oligogalacturonides possessing termini of galactaric acid. Oxidation of indole-3-acetic acid by peroxidases was activated by oxidized oligogalact...

Here we report the whole-genome sequences of three endophytic bacteria, Enterobacter sp. strain DC1, Enterobacter sp. strain DC3, and Enterobacter sp. strain DC4, from root tubers of the yellow yam plant, Dioscorea cayenensis. Preliminary analyses suggest that the genomes of the three bacteria contain genes involved in acetoin and indole-3-acetic acid metabolism.
