The genus Solanum is among the most species-rich genera both of the Peruvian flora and of the tropical Andes in general. The present revised checklist treats 276 species of Solanum L., of which 253 are native, while 23 are introduced and/or cultivated. A total of 74 Solanum species (29% of native species) are endemic to Peru. Additional 58 species occur only in small number of populations outside Peru, and these species are here labelled as near-endemics to highlight the role Peru playes in their future protection. Species diversity is observed to peak between 2500 – 3000 m elevation, but endemic species diversity is highest between 3000 – 3500 m elevation. Cajamarca has the highest number of endemic (29 spp.) and total species (130 spp.), even when considering the effect of area. Centers of endemic species diversity are observed in provinces of Cajamarca (Cajamarca), Huaraz and Carh...

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 cl...
