Genome-wide CNV analysis reveals variants associated with high-altitude adaptation and meat traits in Qaidam cattle

BACKGROUND Qaidam cattle are local breeds that habitats in northwest China. It has many excellent characteristics, such as high cold and roughage tolerance, low oxygen adaptability, and tender meat quality. Copy number variation (CNV) can induce phenotypic changes in animals by a variety of effects, and ...

A key for hypoxia genetic adaptation in alpaca could be a HIF1A truncated bHLH protein domain

Animals exposed to hypobaric hypoxia triggers a physiological hypoxia response via Hypoxia Inducible Factor (HIF) proteins that functions as transcriptional complexes. As the South American camelids inhabit at high Andean altitudes we have asked if they have developed genetic adaptations to live at high ...

Función ventricular derecha en residentes nativos a gran altura

Los adaptados genéticamente a la altura son los tibetanos, sherpas y etíopes; los aymaras y quechuas están aclimatados (Bolivia, Perú y norte de Chile). En Bolivia el mal crónico de montaña afecta 10% de la población masculina. El objetivo fue determinar la función ventricular derecha en resident...

Minor temperature shifts do not affect chromosomal ploidy but cause transcriptomic changes in Leishmania braziliensis promastigotes in vitro

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND The leishmaniases are complex neglected diseases caused by protozoan parasites of the genus Leishmania. Leishmania braziliensis is the main etiological agent of cutaneous leishmaniasis in the New World. In recent studies, genomic changes such as chromosome and gene copy number variations (CNV...

DNA sequence variation of drought-response candidate genes in Austrocedrus chilensis

Electron. j. biotechnol; 16 (2), 2013
Background: Austrocedrus chilensis (D. Don) Pic. Ser. et Bizzarri commonly known as Patagonian cypress is a member of the Cupressaceae family, characterized by a high adaptive potential for growing in marginal areas and good timber quality. The species grows over a wide area and under a wide range of rai...

Phenotypic plasticity in fish life-history traits in two neotropical reservoirs: Petit-Saut Reservoir in French Guiana and Brokopondo Reservoir in Suriname

Neotrop. ichthyol; 7 (4), 2009
Fish species are known for their large phenotypic plasticity in life-history traits in relation to environmental characteristics. Plasticity allows species to increase their fitness in a given environment. Here we examined the life-history response of fish species after an abrupt change in their environm...
