Abstract:

Throughout the years, three infrageneric classifications were proposed for Tradescantia along with several informal groups and species complexes. The current infrageneric classification accepts 12 sections – with T. sect. Tradescantia being further divided into four series – and assimilates many concepts adopted by previous authors. Recent molecular-based phylogenetic studies indicate that the currently accepted sections might not represent monophyletic groups within Tradescantia. Based on newly gathered morphological data on the group, complemented with available micromorphological, cytologic

Abstract:

We present a new record to the Brazilian territory (i.e. Tradescantia boliviana), the rediscovery of a species exclusively known from the cultivated type collection (i.e. T. valida), the description of a new taxon (i.e. T. chrysophylla), synonyms for T. crassula and T. boliviana, correct the typification of T. crassula, and designation of a lectotype for T. ambigua and T. ambigua var. pilosula. Furthermore, we present illustrations, comments, distribution maps, and identification keys for the studied taxa.

Abstract:

I present the first taxonomic revision for T. subg. Austrotradescantia, based on extensive field, cultivation and herbaria studies. I accept 13 species, three of them (i.e. T. atlantica, T. hertweckii and T. tucumanensis) being described as new in the present study. I provide an identification key to the species, distribution maps, descriptions, comments, conservation assessments and illustrations for all species. The troublesome weed T. fluminensis has its specific limits clarified and its native range is presented so it can serve as a basis to better understanding its ecological requirements

Abstract:

A new species of Tradescantia sect. Austrotradescantia endemic to rocky cliffs in Southern Brazil, is here described as Tradescantia seubertiana. This new species is characterized as being completely glabrous, with a leaf base obtuse to cordate to slightly amplexicaulous, ellipsoid flower buds, by its light-pink to pink petals, and for growing in wet rocky cliffs. The new species is morphologically most similar to T. crassula due to its erect habit, conduplicate to canaliculate, succulent leaves, with inconspicuous secondary veins, non-saccate cincinni bracts, pistil longer than the stamens an

Abstract:

Spring Lake reservoir of Macomb, Illinois, is a typical model of the drinking water supply of some midwestern towns of the United States. Water samples collected periodically in 1980 and 1981 from this lake were tested for mutagenicity using the Tradescantia micronucleus (Trad-MCN) test, a highly sensitive mutagen-detecting bioassay. Water samples from 1981 were also analyzed chemically. The micronucleus (MCN) frequency peaked (12–14 MCN/100 tetrads) in mid-July in both years, as compared with the average frequency (5 MCN/100 tetrads) of the base-line control that was maintained in nutrient so

Abstract:

The objective of the present study was to apply a highly sensitive botanical test of mutagenicity (the Tradescantia stamen-hair mutation bioassay) to assess in situ the biological responses induced by naturally occurring radiation in the Poços de Caldas Plateau. The mutagenesis was evaluated in environments presenting gamma radiation exposure rates ranging from 1.5 muR.min-1 up to 100.0 muR.min-1. The results consistently showed only borderline increases in mutation frequencies in plants exposed to areas with high radiation background, as compared to non-exposed plants. It was concluded that t

Abstract:

Within a population of Tradescantia commelinoides collected in the wild, genomic instability is unique to clones having large centric shifts. Initially, the instability is attributable to breakage caused by imperfect separation of abnormally long chromatids, but the more severe effects that sometimes develop are a consequence of spontaneous breakage and reunion and disturbance of control mechanisms. Breakage of excessively long chromatids following repositioning of the centromere may destabilize some segment of DNA important for ordered replication and division. Eventual stability would result

Os hidrocarbonetos Aromáticos Policíclicos, como o Naftaleno, são considerados poluentes orgânicos prioritários em estudos ambientais. Alguns apresentam elevado potencial de toxicidade e podem ser precursores de efeitos mutagênicos e carcinogênicos. O teste de micronúcleo é uma ferramenta sensível na detecção de eventos clastogênicos e aneugênicos ocasionados por xenobióticos. O objetivo deste trabalho foi avaliar a mutagenicidade do naftaleno após exposição aguda em um modelo animal e um vegetal.
