Linum spp. (Linaceae) has been shown to accumulate cytotoxic lignans such as podophyllotoxin and 6-methoxypodopyllotoxin. Therefore, plant cell and tissue cultures of Linum spp. may be possible alternative sources for the lignan production. In this study, we focused on the production of lignans by root cultures of Linum spp. Hairy root cultures of L. nodiflorum, L.album and L. austriacum and ro...
Background & Aim:A new sustainable tissue-based system is presented by plant hairy roots, preserving all of the several specialized types of cell with critical roles in allowing bioactive secondary molecules to be synthesized more consistently as usual. The system is also essential for studying the production of alkaloid in culture. Experimental: The ...
hairy root systems are formed by transforming plant tissues with the “natural genetic engineer” agrobacterium rhizogenes. in most plants such as cichorium intybus l., hairy root cultures have proven to be an efficient system for secondary metabolites production. the effect of zinc (znso4), a heavy metal, was investigated at different concentrations (0, 1, 5 and 10 mm) on some secondary metaboli...
[Context and Motivation] A hairy requirements or software engineering task involving natural language (NL) documents is one that is not inherently difficult for NL-understanding humans on a small scale but becomes unmanageable in the large scale. A hairy task demands tool assistance. Because humans need help in carrying out a hairy task completely, a tool for a hairy task should have as close t...
hairy encodes a bHLH repressor that regulates several developmental processes in Drosophila, including embryonic segmentation and neurogenesis. Segmentation repressors such as Krüppel and knirps have been shown to function over short distances, less than 50-100 bp, to inhibit or quench closely linked upstream activators. This mode of repression permits multiple enhancers to work independently o...
A method named "bag culture" was developed for coculturing of Linum persicum (section Syllinum) and L. austriacum (section Linum) hairy roots. For this propose L. austriacum and L. persicum hairy root cultures were established using Agrobacterium rhizogenes in McCown medium. L. persicum hairy roots in bags (1 mm2 mesh) were successfully grown together with L. austriacum hairy roots. The amounts...
Drosophila C-terminal binding protein (dCtBP) and Groucho have been identified as Hairy-interacting proteins required for embryonic segmentation and Hairy-mediated transcriptional repression. While both dCtBP and Groucho are required for proper Hairy function, their properties are very different. As would be expected for a co-repressor, reduced Groucho activity enhances the hairy mutant phenoty...
The electrophoretic mobility distributions of hairy cells, normal monocytes. CLL, and normal lymphocytes isolated from blood were determined by electrophoretic light scattering. Values obtained for hairy cells, 1.52 X 10(-4) cm2/V . sec, were indistinguishable from that of normal monocytes. The mobility of CLL lymphocytes was similar to that of normal B cells. After exposure to neuraminidase, h...
Macro and micro-elements, carbon sources and elicitors play a central role during Panax ginseng hairy root growth, biomass and ginsenoside production and also influence numerous root developmental stages in largescale bioreactor culture. Due to the lack of biosynthetic nutrients and signalling-inducing nutrients, the regulatory role of mineral elements is not well understood. We have geneticall...
