Meiotic and mitotic behaviour of B chromosomes of ryegrass. ABSTRACT - Mitotic and meiotic analyses using conventional and fluorescent stains were employed in plants (accession ETBAZ 055 - origin: Capão do Leão, Rio Grande do Sul State, Brazil) from the Germpl... ... Repository: BDPA Publication year: 2010
Detection of quantitative trait loci for growth traits on bovine chromosome 2. Classical quantitative genetic approach is applied successfully to improve livestock production using phenotype and pedigree information to estimate population genetic parameters such as heritabilitie... ...

PS-P-1679 Chromosome evolution in Passiflora: from chromosome numbers to single-copy and repetitive DNA sequences. 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
Revisiting the cytogenetics of Vellozia Vand.: immunolocalization of KNL1 elucidates the chromosome number for the genus. Chromosome number is the most fundamental trait of a karyotype. Accurate chromosome counting is essential for further analyses including cytogenomics, taxonomic, evolutionary, and genomic studies. Des... ... Repository: BDPA Publication year: 2025
Chromosomal distribution and evolution of abundant retrotransposons in plants: gypsy elements in diploid and polyploid Brachiaria forage grasses. Repository: BDPA Publication year: 2015
Stability in chromosome number and DNA content in synthetic tetraploids of Lolium multiflorum after two generations of selection. ABSTRACT - Chromosome doubling of Italian ryegrass genotypes ( Lolium multiflorum Lam.) adapted to the brazilian edaphoclimatic conditions is an important strategy used by breeders and aims to obtain... ...

IAPT chromosome data 36/4. Repository: BDPA Publication year: 2022
Chromosome number, microsporogenesis, microgametogenesis, and pollen viability in the Brazilian native grass Mesosetum chaseae (Poaceae). 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. 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... ... Repository: BDPA Publication year: 2017
Chromosome duplication in Lolium multiflorum Lam. 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
