Disease relevance of Tradescantia

• Liquid suspension cell cultures of Tradescantia clone 03 and Tradescantia clone 4430 were used to activate the promutagen m-phenylenediamine into a mutagenic compound which was detected by Salmonella typhimurium strain TA98 in the plant cell/microbe coincubation assay [1].
• For this purpose, fluorescent dye kiton red (sulforhodamine B) was loaded into a variety of cells such as Swiss 3T3 fibroblasts, human mononuclear cells, Sarcoma-180 tumor cells, Chinese hamster ovary cells, plant cells from Digitalis lanata, stamen hair cells of Tradescantia, and guard mother cells of Allium cepa [2].

High impact information on Tradescantia

• Carboxyfluorescein-labeled brain tubulin has been microinjected into stamen hair cells of Tradescantia, and its distribution during mitosis and cytokinesis was examined using confocal laser scanning fluorescence microscopy [3].
• The effect of exogenous abscisic acid on stomatal development, stomatal mechanics, and leaf gas exchange in Tradescantia virginiana [4].
• In SNP-treated leaves of Tradescantia sp., the stomatal closure was correlated with a 10% increase on RWC [5].
• Gas exchange parameters and stomatal physical properties were measured in Tradescantia virginiana plants grown under well-watered conditions and treated daily with either distilled water (control) or 3.0 mM abscisic acid (ABA) [4].
• Here we report that kinetin, a synthetic cytokinin, and rANP induce stomatal opening in Tradescantia albiflora and that the effect of rANP is critically dependent on the secondary structure of the peptide hormone [6].

Biological context of Tradescantia

• The model predicts that chromosomes in haploid Tradescantia microspores have the folded Rab1 orientation; this explains quantitatively the low value of the ratio of dicentrics to centric rings observed in these cells [7].
• Vinylidene chloride gave positive results for gene reversion and conversion in yeast that was also dependent on metabolic activation, and was positive in tradescantia [8].

Associations of Tradescantia with chemical compounds

• Mature pollen grains of Tradescantia are free cells which can be cultured in lactose-agar medium [9].
• We conclude that the 5-phosphatase pathway is the preferred pathway for Ins(1,4,5)P3 inactivation in the stamen hair cells of Tradescantia [10].
• The plant activation of m-phenylenediamine by Tradescantia clone 03 and clone 4430 cells in liquid suspension culture [1].
• Reduction in the frequency of N-methyl-N-nitrosourea-induced somatic mutations in Tradescantia by pretreatment with low doses of alkylating agents [11].
• Three isomers of the promutagen phenylenediamine at mM concentrations were plant-activated and induced mutation in stamen hairs of Tradescantia clone 4430 [12].

Gene context of Tradescantia

• Finally, we quantified the effects of microinjection of each profilin isoform on the cytoarchitecture of Tradescantia stamen hair cells and show that the resultant disruption can be used to compare actin-binding proteins in living cells [13].
• Aqueous soil extracts induced only weak effects in Trad MCN tests and no effects in the root tip assays, whereas cultivation of the plants in the soils resulted in a pronounced induction of MCN in the Tradescantia system and moderate effects in Vicia and Allium [14].
• Isolation of H+ -translocating ATPase in tonoplast of Tradescantia virginiana L. leaf cells [15].
