Chemically induced enucleation of activated bovine oocytes: chromatin and microtubule organization and production of viable cytoplasts. Author(s): SARAIVA, N. Z.; OLIVEIRA, C. S.; LEAL, C. L. V.; CALLADO, M. del; VANTINI, R.; MONTEIRO, F. M.; NICIURA, S. C. M.; GARCIA, J. M. As the standard enucleation method in mammalian nuclear transfer is invasive and damaging to cytoplast spatial organization, alternative procedures have been developed over recent years. Among these t... ... Repository: BDPA Publication year: 2015
Chromatin structural changes around satellite repeats on the female sex chromosome in Schistosoma mansoni and their possible role in sex chromosome emergence. Author(s): LEPESANT, J. M. J.; COSSEAU, C.; BOISSIER, J.; FREITAG, M.; PORTELA, J.; CLIMENT, D.; PERRIN, C.; ZERLOTINI, A.; GRUNAU, C. Background: In the leuphotrochozoan parasitic platyhelminth Schistosoma mansoni, male individuals are homogametic (ZZ) whereas females are heterogametic (ZW). To elucidate the mechanisms that led to t... ... Repository: BDPA Publication year: 2012
Novel putative causal mutations associated with fat traits in Nellore cattle uncovered by eQTLs located in open chromatin regions. Author(s): GARCIA, I. S.; VIGNATO, B. S.; CESAR, A. S. M.; PETRINI, J.; SILVA, V. H. DA; MOROSINI, N. S.; GOES, C. P.; AFONSO, J.; SILVA, T. R. DA; LIMA, B. D.; CLEMENTE, L. G.; REGITANO, L. C. de A.; MOURÃO, G. B.; COUTINHO, L. L. Intramuscular fat (IMF) and backfat thickness (BFT) are critical economic traits impacting meat quality. However, the genetic variants controlling these traits need to be better understood. To advance... ... Repository: BDPA Publication year: 2024

DE; VANTINI, R.; MONTEIRO, F. M.; NICIURA, S. C. M.; GARCIA, J. M. Repository: BDPA Publication year: 2013
Effects of trichostatina, a chromatin-modifying agent, on meiotic progression of bovine oocytes and embryonic development. Author(s): SARAIVA, N. Z.; OLIVEIRA, C. L.; DEL COLLADO, C. L.; LIMA, M. R. de; VANTINI, R.; MONTEIRO, F. M.; NICIURA, S. C. M.; GARCIA, J. M. One important aspect that has been the subject of recent research is the role of epigenetics in oocyte competence acquisition. Repository: BDPA Publication year: 2013
Chromatin differentiation between Vigna radiata (L.) R. Wilczek and V. unguiculata (L.) Walp. (Fabaceae). Author(s): BORTOLETI, K. C. de A.; ISEPPON, A. M. B.; MELO, N. F. de; VIDAL, A. C. B. The present work reassesses the karyotype of both species also using CMA 3 /DAPI fluorochrome staining, as well as FISH with 5S and 45S rDNA probes, revealing some divergent features when compared wit... ...

In perennial plants, the release of bud dormancy, with subsequentflowering, resemblesthe vernalization process ofArabidopsis thalianaand cereals. Especially for perennialcrops from temperate regions,... ... Repository: BDPA Publication year: 2019

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... ...
