Análisis de Polimorfismos en el Genoma de Cuy (Cavia porcellus) asociados a características de Importancia Económica
(Instituto Nacional de Innovación Agraria, 2020) Carrillo Castillo, Fredesvinda
El proyecto “Análisis de polimorfismos en el genoma de cuy Cavia porcellus asociados a características de importancia económica”, tuvo como propósito identificar regiones a lo largo del genoma de cuy asociadas a características de importancia económica, mediante tecnologías de Secuenciamiento de Nueva Generación (NGS) y análisis bioinformáticos

En el presente estudio, se ha reconstruido la secuencia completa del genoma plastidial del maíz morado peruano y se ha comparado con otros genomas plastidiales de maíces. El genoma plastidial tiene una longitud de 140,458 pb y muestra una estructura típica del genoma del cloroplasto: un par de regiones repetidas invertidas (IRa e IRb) de 22,594 pb, una región Larga de Copia Única (LSC) de 82,472 pb, y una región Corta de Copia Única (SSC) de 12,798 pb. Las relaciones filogenéticas fueron obtenidas a partir de alineamientos genómicos completos con los genomas plastidiales de otros miembros del género Zea. Los resultados indicaron que el maíz morado peruano está más relacionado a Z. mays subsp. huehuetenangensis. Es posible que eventos de hibridación introgresiva a lo largo de la evolución del maíz morado hayan jugado un papel en la adquisición del fenotipo morado en el clado Z. mays.
Draft genome sequence data of Fusarium verticillioides strain REC01, a phytopathogen isolated from a Peruvian maize

Fusarium verticillioides represents a major phytopathogenic threat to maize crops worldwide. In this study, we present genomic sequence data of a phytopathogen isolated from a maize stem that shows obvious signs of vascular rot. Using rigorous microbiological identification techniques, we correlated the disease symptoms observed in an affected maize region with the presence of the pathogen. Subsequently, the pathogen was cultured in a suitable fungal growth medium and extensive morphological characterization was performed. In addition, a pathogenicity test was carried out in a DCA model with three treatments and seven repetitions. De novo assembly from Illumina Novaseq 60 0 0 sequencing yielded 456 contigs, which together constitute a 42.8 Mb genome assembly with a GC % content of 48.26. Subsequent comparative analyses were performed with other Fusarium genomes available in the NCBI database.

The genus Passiflora comprises a large group of plants popularly known as passion fruits, much appreciated for their exotic flowers and edible fruits. The genus has long attracted considerable attention due to its economic value, broad geographic distribution and remarkable species diversity, which are found in tropical and subtropical regions of the Neotropics. Despite their biological attributes and economic importance, the species are largely neglected when it comes to conducting genomic studies. However, in 2021, a chromosome-scale genome assembly was published for a purple passion fruit cultivar (Passiflora edulis) and a genome sequence resource of the wild species, P. organensis, was assembled by adopting short- and long-read technologies. In contrast to P. edulis (1,327 Mbp), P. organensis has a small genome (259 Mbp). In this chapter we summarize some interesting results that emerged from the analysis of the Passiflora sequences, including satellite DNAs and transposable element characterization in the context of cytogenetics and evolution of the genus, organellar genome organization, and the MADS-box gene family that is known to have important biological roles in Passiflora, especially with regard to reproductive development. Although understudied, over the last decades, work on breeding passion fruit varieties has been conducted in some private and public institutions with a view to releasing cultivars of P. edulis, the main cultivated species worldwide. Therefore, studies related to genetics and breeding are also summarized.
