Interphase nuclei, karyotypes and nuclear DNA amounts in five species of Oenocarpus (Arecaceae). The genus Oenocarpus Martius, 1823 (Arecaceae) includes five species commonly used in Amazonia, especially for their fruits. Little is known about the cytogenetic characteristics and DNA amounts of th... ... Repository: BDPA Publication year: 2024
The karyotype of Adenia and the origin of the base number x = 12 in Passifloroideae (Passifloraceae). Adenia is an Old World genus of Passifloroideae closely related to Passiflora. The two genera comprise the large majority of Passifloroideae species, although most studies are concentrated on Passiflo... ... Repository: BDPA Publication year: 2021
Karyotype variability in species of the genus Zephyranthes Herb. (Amaryllidaceae-Hippeastreae). Abstract In this work, the cytotaxonomic implications of the chromosomal characterization of cultivated and native Zephyranthes species described in northeastern Brazil were studied. All individuals h... ... Repository: BDPA Publication year: 2011
Karyotypic diversity and evolutionary trends in the Neotropical catfish genus Hypostomus Lacépède, 1803 (Teleostei, Siluriformes, Loricariidae). The family Loricariidae with 813 nominal species is one of the largest fish families of the world. Hypostominae, its more complex subfamily, was recently divided into five tribes. The tribe Hypostomin... ... Repository: BDPA Publication year: 2012
Chromosome study in Schistocerca (Orthoptera-Acrididae-Cyrtacanthacridinae): karyotypes and distribution patterns of constitutive heterochromatin and nucleolus organizer regions (NORs). Chromosome analyses were performed in two grasshopper species of the genus Schistocerca, S. pallens and S. flavofasciata. Both species shared the same diploid number (2n = 23, X in males; 2n = 24, XX... ... Repository: BDPA Publication year: 2007
Karyotypic studies of Cratylia argentea (Desv.) O. Kuntze and C. mollis Mart. ex Benth. (Fabaceae - Papilionoideae). Cratylia argentea and C. mollis (Fabaceae-Papilionoideae) are legume shrubs native to the Cerrado and Caatinga, respectively. Both species show great resistance to drought and high nutritive value, wh... ... Repository: BDPA Publication year: 2007
Karyotype asymmetry in Cynodon Rich. (Poaceae) accessions. Abstract Cynodon is a genus of plants with forage potential that has attracted the interest of breeders. These species have high morphological variability in a large number of varieties and cytotypes,... ... Repository: BDPA Publication year: 2016
Karyotype and genome size in Euterpe Mart. (Arecaceae) species. Euterpe (Martius, 1823), a genus from Central and South America, has species with high economic importance in Brazil, because of their palm heart and fruits, known as açaí berries. Breeding programs h... ... Repository: BDPA Publication year: 2016
Karyotypic evolution of ribosomal sites in buffalo subspecies and their crossbreed. Domestic buffaloes are divided into two group based on cytogenetic characteristics and habitats: the "river buffaloes" with 2n = 50 and the "swamp buffaloes", 2n = 48. Nevertheless, their hybrids are... ... Repository: BDPA Publication year: 2014
Karyotype characterization and comparison of three hexaploid species of Bromus Linnaeus, 1753 (Poaceae). In this study, the aims were to determine the nuclear genome size and characterize the karyotype of the South American Bromus species: Bromus auleticus Trinius ex Nees, 1829, Bromus brachyanthera Döll... ...
