Journal ArticleDOI
Single nucleotide variants and InDels identified from whole-genome re-sequencing of Guzerat, Gyr, Girolando and Holstein cattle breeds
Nedenia Bonvino Stafuzza,Adhemar Zerlotini,Francisco Pereira Lobo,Michel Eduardo Beleza Yamagishi,T.C.S. Chud,Alexandre Rodrigues Caetano,Danísio Prado Munari,Dorian J. Garrick,Marco Antonio Machado,Marta Fonseca Martins,Maria Raquel Santos Carvalho,John B. Cole,Marcos Vinícius Gualberto Barbosa da Silva +12 more
TL;DR: The genetic variants discovered here provide a rich resource to help identify potential genomic markers and their associated molecular mechanisms that impact economically important traits for Gyr, Girolando, Guzerat and Holstein breeding programs.
Journal ArticleDOI
Nosema ceranae has been present in Brazil for more than three decades infecting Africanized honey bees
Érica Weinstein Teixeira,Lubiane Guimarães dos Santos,Aroni Sattler,Dejair Message,Maria Luisa Teles Marques Florêncio Alves,Marta Fonseca Martins,Marina Lopes Grassi-Sella,Tiago Maurício Francoy +7 more
TL;DR: The morphometric results indicated that the population collected in 1979 was significantly different from the current living population, confirming its antiquity, and it is concluded that N. ceranae has been affecting Africanized honeybees in Brazil for at least 34 years, the impact of this pathogen remains unclear.
Journal ArticleDOI
Honey bee colonies act as reservoirs for two Spiroplasma facultative symbionts and incur complex, multiyear infection dynamics
Ryan S. Schwarz,Érica Weinstein Teixeira,James P. Tauber,Juliane M Birke,Marta Fonseca Martins,Isabela Fonseca,Jay D. Evans +6 more
TL;DR: The findings demonstrate that the model of honey bee spiroplasmas as springtime‐restricted pathogens needs to be broadened and their role as occasional pathogens considered in current contexts.
Journal ArticleDOI
Genetic parameters of milk production and reproduction traits of Girolando cattle in Brazil
Ali William Canaza-Cayo,Paulo Sávio Lopes,Jaime Araujo Cobuci,Marta Fonseca Martins,Marcos Vinícius Gualberto Barbosa da Silva +4 more
TL;DR: The results of this study reveal large genetic, phenotypic and environmental variations that could be used in selection programmes.
Journal ArticleDOI
Polymorphism in the PPARgamma2 and beta2-adrenergic genes and diet lipid effects on body composition, energy expenditure and eating behavior of obese women.
Eliane Lopes Rosado,Josefina Bressan,Marta Fonseca Martins,Paulo Roberto Cecon,Jose Alfredo Martínez +4 more
TL;DR: The Pro12Ala/Gln27Glu group was found to present greater energy used in postprandial period (EUPP), and the presence of the PPARgamma2 gene variant, independent of beta2-adrenergic gene polymorphism, resulted in fat oxidation increase.
