PS-P-1679 Chromosome evolution in Passiflora: from chromosome numbers to single-copy and repetitive DNA sequences. Author(s): SADER M. A.; DIAS, Y.; MUNHOZ, C.; PENHA, H.; AMORIM, B. S.; COSTA, L.; VAIO, M.; SANTOS L. A. C.; DORNELAS, M. C.; BERGES, H.; MELO, N. F. de; SOUZA, G.; VIEIRA, M. L.; PEDROSA-HARAND, A. Passiflora L. has around 500 species mainly distributed in the Neotropics. The genus shows different basic chromosome numbers associated to different subgenus (x = 6, 9 and 12) and high variation in g... ... Repository: BDPA Publication year: 2018
Chromosomal distribution and evolution of abundant retrotransposons in plants: gypsy elements in diploid and polyploid Brachiaria forage grasses. Author(s): SANTOS, F. C.; VALLE, C. B. do; CHIARI, L. Repository: BDPA Publication year: 2015
Cytotaxonomy and karyotype evolution in Neotropical Meliponini (Hymenoptera: Apidae) inferred by chromosomal mapping of 18S rDNA and five microsatellites. Author(s): CUNHA, M. S.; GARCIA, M. V. B.; CAMPOS, L. A. O.; LOPES, D. M. The Neotropical Meliponini bees, commonly known as stingless bees, are phylogenetically subdivided into three clades in which the chromosome numbers vary from n 1⁄4 8 to n 1⁄4 17. The goal... ...

Chromosome number, microsporogenesis, microgametogenesis, and pollen viability in the Brazilian native grass Mesosetum chaseae (Poaceae). Author(s): SILVA, L. A. C.; PAGLIARINI, M. S.; SANTOS, S. A.; SILVA, N.; SOUZA, V. F. The genus Mesosetum is a primarily South American genus with 42 species. Mesosetum chaseae, regionally known as ?grama-do-cerrado?, is abundant in the Pantanal Matogrossense (Brazil); it is a valuable... ... Repository: BDPA Publication year: 2012
Dynamics of 45S rDNA sites in the cell cycle: fragile sites and chromosomal stability in Lolium and Festuca. Author(s): ROCHA, L. C.; SILVA, G. A.; BUSTAMANTE, F. O.; SILVEIRA, R. A. D.; MITTELMANN, A.; TECHIO, V. H. Abstract Analyses carried out with fluorescence in situ hybridization (FISH) in C-metaphases of the Lolium-Festuca complex have shown the occurrence of spontaneous fragile sites (FSs) in 45S rDNA regi... ...

Chromosome duplication in Lolium multiflorum Lam. Author(s): PEREIRA, R. C.; FERREIRA, M. T. M.; DAVIDE, L. C.; PASQUAL, M.; MITTELMANN, A.; TECHIO, V. H. Artificial chromosome duplication of diploid genotypes of Lolium multiflorum (2n=2x=14) is worthy to breeding, and aims to increase the expression of traits with agronomic interest. The purpose of thi... ... Repository: BDPA Publication year: 2014
