(n.) An American endogenous plant (Tradescantia Virginica), with long linear leaves and ephemeral blue flowers. The name is sometimes extended to other species of the same genus.
Example Sentences:
(1) Cells from immature stamen hairs of the spiderwort plant Tradescantia virginiana cv.

(3) Stamen hair cells from the spiderwort plant, Tradescantia virginiana, exhibit remarkably predictable metaphase transit times, making them uniquely suitable for temporal studies on mitotic regulation.
(4) We have treated stamen hair cells of the spiderwort plant, Tradescantia virginiana, with a solution of quin2 (50 microM) or its acetoxymethyl ester, quin2-AM (50 microM) and have retarded the normally predictable rate of progression through metaphase.
Tradescantia
Definition:
(n.) A genus including spiderwort and Wandering Jew.
Example Sentences:
(1) This assemblage is called the Tradescantia-micronucleus image analysis (Trad-MCNIA) system.

(3) Cells from immature stamen hairs of the spiderwort plant Tradescantia virginiana cv.
(4) A modified fluorescence-plus-Giemsa technique is described that allows differential staining of sister chromatids in root tip cells from cuttings of Tradescantia paludosa.
(5) The Tradescantia-micronucleus (Trad-MCN) bioassay was used to determine the clastogenicity of wastewater samples collected from the Arena canal which contains effluent from the industrial district Benito Juarez of the city of Queretaro, Mexico.
(6) Ethanol leads to anomalous chromosome segregation in Aspergillus, to mutations in yeast, to chromosomal aberrations and SCEs in plant root tips and to disturbances of meiosis and micronuclei in tetrads in Zea and Tradescantia respectively.
(7) The normally predictable duration of metaphase in stamen hair cells from the spiderwort, Tradescantia virginiana, is shortened significantly by treatment during prometaphase with either ruthenium red or Bay K-8644.
(8) Anaphase in dividing guard mother cells of Allium cepa and stamen hair cells of Tradescantia virginiana consists almost entirely of chromosome-to-pole motion, or anaphase A.
(9) Synergistic and antagonistic effects on genotoxicity of mixtures of four chemicals; i.e., lead tetraacetate (LTA), arsenic trioxide (ATO), dieldrin (DED), and tetrachloroethylene (TCE), were evaluated by the Tradescantia-micronucleus (Trad-MCN) assay.
(10) The goal of this study was to determine the genotoxicity of tannic acid alone and its possible synergistic effect with X-rays using the Tradescantia-micronucleus (Trad-MCN) bioassay.
(11) Stamen hair cells from the spiderwort plant, Tradescantia virginiana, exhibit remarkably predictable metaphase transit times, making them uniquely suitable for temporal studies on mitotic regulation.
(12) Another experimental disruption of the relationship, accomplished by making minute wounds in the PPB site of mitotic cells in Tradescantia stamen hairs, is described.
(13) For example, the cdt in root meristems of Zea mays decreases 21-fold as the temperature is increased from 3 to 25 degrees C. Whether all phases of the cell cycle alter proportionately with temperature has been ascertained by comparing data from the root meristem of five species: Pisum sativum, Helianthus annuus, Tradescantia paludosa, Allium cepa and Triticum aestivum.
(14) In order to test whether this influences the initial, linear component in the dose-effect relations, a comparison was made between dose-response curves for pink somatic mutations in Tradescantia clone 02 stamen hairs following X and gamma irradiations.
(15) The use of the Tradescantia stamen-hair system is inexpensive and requires only a short training time.
(16) In addition, Tradescantia clone 4430 was exposed to tank diesel in the laboratory at concentration levels equivalent to exposure at 15 and 50 m. Tradescantia clones were examined for mutagenic effects indicated by micronuclei induction in developing pollen and pink somatic mutations in stamen hairs.
(17) A pollen grain in Tradescantia reflexa consists of two cells, the generative and the vegetative cells, the generative cell being surrounded completely by the vegetative cell.
(18) To determine the fraction of cells that will respond quantally (be transformed) after receiving a hit of a given size, a hit size effectiveness function (HSEF) which appears to have a threshold has been derived from experimental data for pink mutations in Tradescantia.
(19) Dose-response curves for pink somatic mutations in Tradescantia stamen hairs were analyzed after neutron and x-ray irradiation with doses ranging from a fraction of a rad to the region of saturation.
(20) Vinylidene chloride gave positive results for gene reversion and conversion in yeast that was also dependent on metabolic activation, and was positive in tradescantia.
