Última Cytogenetic characterization of Aloysia virgata Ruiz and Pavan (Verbenaceae) BABT Brandão,Aline Dias; Viccini,Lyderson Facio; Recco-Pimentel,Shirlei Maria. Since previous cytogenetic reports of Aloysia have only described the meiotic behavior and chromosomal number of some species, the aim of this work was to provide detailed cytogenetic description of Aloysia virgata that would contribute to the understanding of the taxonomical organization of the Verbenaceae. Aloysia virgata had a karyotype with 2n = 36 metacentric chromosomes, all with similar size. The large amount of heterochromatin seen after Giemsa staining was confirmed by C-banding. Four nucleolar organizer regions (NORs) were detected with an rDNA 45S probe in two homologous pairs and two sites of 5S rDNA located on one chromosomal pair were detected by fluorescence in situ hybridization. The interphase nucleus was classified as semi-reticulate.... Tipo: Info:eu-repo/semantics/article Palavras-chave: Chromosome; Cytogenetic characterization; FISH; Aloysia; Verbenaceae.
