Comparative RNAseq analysis of backfat tissue from local pig breeds.
Albuquerque, A.; Óvilo, C.; Núñez, Ý.; Benítez, R.; Lopez-Garcia, A.; Garcia, F.; Laranjo, M.; Charneca, R.; Martins, J.M.Alentejano (AL) and Bísaro (BI) are the main local pig breeds in Portugal, but have no information comparing their transcriptomic activity. AL belongs to the Iberian branch, presenting lower growth rates, precociously high adipogenic activity and higher levels of unsaturated fatty acids (FAs) while BI pig is from the Celtic group, sharing ancestors with higher growth rate and leaner commercial breeds. This work...
Transcriptomic profiling of skeletal muscle reveals candidate genes influencing...
Albuquerque, A.; Óvilo, C.; Núñez, Y.; Benítez, R.; López-Garcia, A.; Félix, M.R.; Laranjo, M.; Charneca, R.; Martins, J.M.Gene expression is one of the main factors to influence meat quality by modulating fatty acid metabolism, composition, and deposition rates in muscle tissue. This study aimed to explore the transcriptomics of the Longissimus lumborum muscle in two local pig breeds with distinct genetic background using next-generation sequencing technology and Real-Time qPCR. RNA-seq yielded 49 differentially expressed genes be...
Identification of differentially expressed key genes of Longissimus lumborum sa...
Albuquerque, A.; Óvilo, C.; Núñez, Y.; Benítez, R.; Lopéz-García, A.; Ballesteros, J.; García, F.; Laranjo, M.; Charneca, R.; Martins, J.M.Most of the swine industry nowadays is about productive and profitable fast-growing lean breeds raised under intensive conditions leading to meat and fat rich in saturated fatty acids. The Portuguese local Alentejano (AL) and Bísaro (BI) pig breeds present high intramuscular fat (IMF) content which contributes to highly appreciated pork products. These breeds have different ancestors: AL belongs to the Iberian ...
Comparative Transcriptomic Analysis of Subcutaneous Adipose Tissue from Local P...
Albuquerque, A.; Óvilo, C.; Núñez, Y.; Benítez, R.; López-Garcia, A.; García, F.; Félix, M.R.; Laranjo, M.; Charneca, R.; Martins, J.M.When compared to modern lean-type breeds, Portuguese local Alentejano (AL) and Bísaro (BI) pig breeds present a high potential for subcutaneous and intramuscular fat (IMF) deposition which contributes for better meat quality. The aim of this work was to explore the genome function to better understand the underlying physiological mechanisms associated with body fat accretion. Dorsal subcutaneous fat samples wer...
Genomic diversity, linkage disequilibrium and selection signatures in European ...
Muñoz, M.; Bozzi, R.; García-Casco, J.; Núñez, Y.; Ribani, A.; Franci, O.; García, F.; Škrlep, M.; Schiavo, G.; Bovo, S.; Utzeri, V. J.; Charneca, R.Genetic characterization of local breeds is essential to preserve their genomic variability, to advance conservation policies and to contribute to their promotion and sustainability. Genomic diversity of twenty European local pig breeds and a small sample of Spanish wild pigs was assessed using high density SNP chips. A total of 992 DNA samples were analyzed with the GeneSeek Genomic Profler (GGP) 70K HD porcin...

Albuquerque, A.; Óvilo, C.; Núñez, Y.; Benítez, R.; Lopez-Garcia, A.; Ballesteros, J.; Garcia, F.; Laranjo, M.; Charneca, R.; Martins, J.M.Portuguese local Alentejano (AL) and Bísaro (BI) pig breeds have a higher potential for subcutaneous and intramuscular fat (IMF) deposition than modern lean-type breeds. AL pig belongs to the Iberian branch, presenting many of the characteristics of this group such as a low growth rate, a precociously high adipogenic activity and a high level of unsaturated fatty acids (FA). BI pig is related to the Celtic grou...
Diversity across major and candidate genes in European local pig breeds
Muñoz, M.; Bozzi, R.; García, F.; Núñez, Y.; Geraci, C.; Crovetti, J.; García-Casco, J.; Alves, E.; Skrlep, M.; Charneca, R.; Martins, J.M.The aim of this work was to analyse the distribution of causal and candidate mutations associated to relevant productive traits in twenty local European pig breeds. Also, the potential of the SNP panel employed for elucidating the genetic structure and relationships among breeds was evaluated. Most relevant genes and mutations associated with pig morphological, productive, meat quality, reproductive and disease...
Diversidad genética de las razas porcinas ibérica y alentejana mediante el geno...
Muñoz, Maria; Bozzi, R.; Crovetti, A.; Charneca, R.; Martins, J.M.; Fernández, A.; Fontanesi, L.; Garcia-Casco, J.M.; Óvilo, C.Las razas porcinas ibérica y alentejana se encuentran biogeográficamente localizadas en el suroeste de la península Ibérica. Estas razas comparten un conjunto de características comunes. Ambas son fenotípicamente muy similares; muestran un bajo índice de crecimiento y una elevada deposición grasa y tienen un sistema común de producción al aire libre en el que se explotan los recursos de la Dehesa. El objetivo d...
