El cuy es un roedor nativo de América del Sur usado como fuente de proteína, animal de compañía, en rituales y como organismo modelo. Su crianza contribuye a la seguridad alimentaria tanto en zonas rurales como en zonas urbanas del Perú. Las investigaciones en nuestro país se han enfocado en aspectos sanitarios y de zootecnia; mientras que el conocimiento a nivel genético ha sido poco abordado. Por ello esta tesis tiene como objetivo evaluar la diversidad genética, la estructura genética y algunos parámetros de la dinámica poblacional del cuy doméstico nativo de las regiones de Huancavelica y Junín mediante microsatélites. Se colectaron 126 individuos Huancavelica y Junín de los cuales se extrajo ADN a partir muestras de folículo piloso. Se realizaron PCR multiplex y los productos de PCR fueron separados en un secuenciador ABI 3130XL. Para los análisis se consideraron 11...

The soil microbiome, a crucial component of agricultural ecosystems, plays a pivotal role in crop production and ecosystem functioning. However, its response to traditional tillage systems in potato cultivation in the Peruvian highlands is still far from understood. Here, ecological and functional aspects of the bacterial community were analyzed based on soil samples from two traditional tillage systems: 'chiwa' (minimal tillage) and 'barbecho' (full tillage), in the Huanuco region of the Peruvian central Andes. Similar soil bacterial community composition was shown for minimal tillage system, but it was heterogeneous for full tillage system. This soil bacterial community composition under full tillage system may be attributed to stochastic, and a more dynamic environment within this tillage system. 'Chiwa' and 'barbecho' soils harbored distinct bacterial genera into their communities, i...

Peru is an important center of diversity for maize; its different cultivars have been adapted to distinct altitudes and water availability and possess an array of kernel colors (red, blue, and purple), which are highly appreciated by local populations. Specifically, Peruvian purple maize is a collection of native landraces selected and maintained by indigenous cultures due to its intense purple color in the seed, bract, and cob. This color is produced by anthocyanin pigments, which have gained interest due to their potential use in the food, agriculture, and pharmaceutical industry. It is generally accepted that the Peruvian purple maize originated from a single ancestral landrace ‘Kculli’, but it is not well understood. To study the origin of the Peruvian purple maize, we assembled the plastid genomes of the new cultivar ‘INIA 601’ with a high concentration of anthocyanins, comp...
