Low cytomolecular diversification in the genus Stylosanthes Sw. (Papilionoideae...
Franco,Ana Luiza; Figueredo,Amanda; Pereira,Lívia de Moraes; Sousa,Saulo Marçal de; Souza,Gustavo; Carvalho,Marcelo Ayres; Simon,Marcelo F.Abstract Stylosanthes (Papilionoideae, Leguminosae) is a predominantly Neotropical genus with ~48 species that include worldwide important forage species. This study presents the chromosome number and morphology of eight species of the genus Stylosanthes (S. acuminata, S. gracilis, S. grandifolia, S. guianensis, S. hippocampoides, S. pilosa, S. macrocephala, and S. ruellioides). In addition, staining with CMA a...
ASSESSMENT OF GENETIC STABILITY OF MICROPROPAGATED Eucalyptus globulus Labill H...
Oliveira,Leandro Silva; Xavier,Aloisio; Otoni,Wagner Campos; Campos,José Marcello Salabert; Viccini,Lyderson Facio; Takahashi,Elizabete KeikoABSTRACT Flow cytometry and microsatellite markers were used to determine a genetic fidelity of micropropagated plants from the two Eucalyptus urophylla x E. globulus clones and a Eucalyptus grandis x E. globulus clone derived from adult material. Clones were repeatedly subcultured for 25 subcultures on MS medium supplemented with BA (2.22 µM) and ANA (0.05 µM) for in vitro shoot multiplication. The elongation ...
Embriogênese somática em híbridos de Pennisetum sp. e avaliação de estabilidade...
Campos,José Marcello Salabert de; Calderano,Clara de Azevedo; Pereira,Antônio Vander; Davide,Lisete Chamma; Viccini,Lyderson FacioOs objetivos deste trabalho foram estabelecer um protocolo eficiente de embriogênese somática, em híbridos triploides entre capim elefante (Pennisetum purpureum Schumach.) e milheto (P. glaucum (L.) R. Br.), e avaliar por citometria de fluxo a estabilidade genômica das plantas obtidas in vitro. A embriogênese somática e a regeneração das plantas foram estabelecidas a partir de embriões zigóticos maduros de híbr...
Cytogenetic characterization of Aloysia virgata Ruiz and Pavan (Verbenaceae)
Brandão,Aline Dias; Viccini,Lyderson Facio; Recco-Pimentel,Shirlei MariaSince 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 a...
