Physalis peruviana “aguaymanto”, es una planta nativa de los andes peruano perteneciente a la familia Solanaceae. Actualmente presenta un creciente interés por parte de los agricultores del Perú debido al aumento en la demanda internacional, lo cual también ha despertado interés por parte del estado. Este fitorecurso posee pocos estudios de diversidad genética en el país, por tal motivo es necesario la caracterización genética entre distintas poblaciones cultivadas y silvestres. Uno de los enfoques utilizados para este fin es el citogenético, siendo las técnicas de Hibridación Fluorescente in situ (FISH) las que tienen mayor resolución que las técnicas de tinción clásica. Esta técnica citomolecular usa sondas de ADN ribosomal (ADNr) 5s y 45s para caracterizar poblaciones mediante su mapeo en los cromosomas evaluando su número de señales y posición. De acuerdo a lo ...

Physalis peruviana (Golden berry) a native fruit of Peru, is an important Andean agricultural crop. Although classical cytogenetics research on this berry has been conducted there is no precise evidence based on molecular cytogenetic studies. The Fluorescent In Situ Hybridization (FISH) technique was applied to reveal 5S rDNA sites in chromosomes of San Pablo and Celendín populations, Cajamarca, Perú. This research was identified the 5S rDNA locus in the two populations of Golden berry, reporting six signals in 3 pairs of chromosomes which would indicate that the species is polyploid. Likewise, no differences were found in the number of 5S rDNA loci between both populations, so we could point out that they would not be different ecotypes.
