Tradescantia pallida cv. purpurea, a popular garden plant in Brazil, was used for the Tradescantia micronucleus (Trad-MCN) assay. In situ monitoring of the genotoxicity of air pollutants was carried out by sentinel approach, using the plant grown in the field or using the plants in pots which were carried to the monitoring sites. Two highly polluted sites, in São Paulo city (Cerqueira Cesar and...

Tradescantia fluminensis Vell. is a perennial, herbaceous species native to tropical regions of Brazil and Argentina which has become established in many lowland native forest remnants of the North Island and northern South Island of New Zealand. Under certain conditions, T. fluminensis spreads rapidly to form a dense mat up to 60 cm in depth which can ‘smother’ ground cover species and prevent...

Regulation of branching within perennial prostrate clonal herbs differs from the annual orthotropic species, Arabidopsis and pea, as the dominant signal transported from roots is a branching promoter, not an inhibitor. Trifolium repens, an exemplar of such prostrate species, was used to investigate the interaction between roots and branch development. This study tests whether or not current kno...

Cytogenetic studies started during the early 1940’s with the studies of Karl Sax on the induction of chromosomal aberration in Tradescantia microspores by X-rays and later it has been applied in the study of human chromosomes. Generally the cytogenetic techniques are useful to estimate radiation doses received due to external radiation exposure it is difficult to estimate radiation doses except...
