Agrobacterium rhizogenes causes hairy root disease in plants. The neoplastic roots produced by A. rhizogenes infection is characterized by high growth rate and genetic stability. These genetically transformed root cultures can produce higher levels of secondary metabolites or amounts comparable to that of intact plants. Hairy root cultures offer promise for production of valuable secondary meta...
The best characterized chromatin insulator in Drosophila is the Suppressor of Hairy wing binding region contained within the gypsy retrotransposon. Although cellular functions have been suggested, no role has been found yet for the multitude of endogenous Suppressor of Hairy wing binding sites. Here we show that two Suppressor of Hairy wing binding sites in the intergenic region between the yel...
Elicitation with middle-viscous chitosan (30 mg/50 mL) significantly stimulated silymarin synthesis in Silybum marianum hairy root cultures. The root cultures established by infection with Agrobacterium rhizogenes AR15834 showed a potential for production of silymarin. Elicitation with medium molecular weight of chitosan (0, 5, 10, 20, and 30 mg/50 mL) was used in order to imp...
The influence of selected plant species on egg hatch and subsequent development of Heterodera glycines race 3 was investigated. Plants tested included four soybean cultivars, red clover, alfalfa, hairy vetch, field corn, sweet corn, cabbage, tobacco, cotton, and wheat. Soybean stimulated egg hatching more than any of the other plant species, with H. glycines-resistant cultivars being more stimu...
Following in vitro infection with Agrobacterium rhizogenes wild strain (mannopine, 8196) and two A. tumefaciens transconjugant strains (C58C1 pArA4abc and C58C1 pArA4b) transformed (hairy) roots were induced in pumpkin (C. pepo L.) cotyledons. The presence of pRi T-DNA in pumpkin long-term hairy root cultures was determined by Southern hybridization. The influence of plant growth regulators on ...
Hairy roots were induced by infecting stems and leaves of Glycyrrhiza inflata with Agrobacterium rhizogenes ATCC 15834. The optimization of growth and glycyrrhizin accumulation of G. inflata hairy roots was studied. Sucrose (6%, w/v) was optimal for growth and glycyrrhizin accumulation in G. inflata hairy roots. Effects of elicitors like chitosan, methyl jasmonate, and yeast extract on glycyrrh...
Hairy root cultures were obtained from diploid and induced tetraploid plants of Datura stramonium and analyzed by gas chromatography/mass spectrometry. Twenty alkaloids (19 for diploid and 9 for tetraploid hairy root cultures) were identified. A new tropane ester 3-tigloyloxy-6-propionyloxy-7-hydroxytropane was identified on the basis of mass spectral data. Hyoscyamine was the main alkaloid in ...
Hairy cell leukemia is a chronic B cell leukemia with a number of distinctive features including the unusual tissue distribution of the leukemic cells, hairy cells, and the bone marrow fibrosis. We have been working, for a number of years, on the potential mechanisms behind hairy-cell localization in tissues. In this review, it is summarized how our work has shed very important information rega...
Strategies to Improve the Production of Forskolin from Hairy Root Cultures of Coleus forskohlii Briq
The aim of this study was to elucidate the effect of elicitors and precursors on the production of forskolin from the hairy root cultures of Coleus forskohlii Briq. Hairy root cultures were established from leaf explants by infecting with Agrobacterium rhizogenes strain A4 on MS basal medium. Suspension cultures of hairy root cultures were initiated in MS medium containing IBA (1.0 mg/L), casei...
UNLABELLED INTRODUCTION Linezolid-induced black hairy tongue has been rarely reported. The purpose of this paper is to report a case of linezolid-induced black hairy tongue and review the literature. CASE PRESENTATION A 56-year-old Caucasian man was admitted with community-acquired pneumonia that failed to respond to levofloxacin 750mg daily. He was started on linezolid and meropenem and w...
