There has been growing interest in the use of rapid and selective separation methods such as high-performance affinity chromatography (HPAC) or affinity capillary electrophoresis (ACE) for the characterization of drug-protein interactions. L-Tryptophan is commonly used in these and other methods as a site-selective probe for examining the binding of small solutes and drugs at Sudlow site II on ...

In our studies on the development of new promoters for the root formation of tree cuttings, 4-trifluoromethylindole-3-acetic acid (4-CF(3)-IAA), a new fluorinated auxin, was synthesized via 4-trifluoromethylindole and 4-trifluoromethylindole-3-acetonitrile by using 2-methyl-3-nitrobenzotrifluoride as the starting material. As a control compound for comparing biological activities, 4-methylindol...

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 ...

Poor seed germination is a major issue in teak (Tectona grandis) propagation. Teak dormancy thought to be the reason for delayed germination. So far, specific mechanisms have not yet been identified. In order study influence of presowing treatments on germination, seedling vigour, and biochemical attributes fresh drupes collected from production area Top Slip Tamil Nadu. The were subjected diff...

The germination percentage of teak seed is generally very poor due to its higher empty and viability. viable seeds exhibit protracted behaviour their inherent dormancy other physiochemical characteristics. Hence establishing a nursery for largescale plantation activities challenging task. This study was undertaken the effect ageing on in vitro true vivo drupe mechanism teak. Fresh, one-year two...
