Tridge summary

An international research team has unraveled the genetic history and global spread of peppers, revealing the role of culinary preferences and food traditions in shaping biodiversity. The study, which analyzed over ten thousand samples from the Capsicum genus, confirmed the Andean region as the origin of wild peppers, with early domestication in South America. The research also identified new centers of genetic diversity in Eastern Europe, Africa, and South East Asia, attributing the spread of sweet and chilli peppers to specific trade routes. The findings have implications for the development of new pepper varieties and sustainable pepper production.

The factors that influenced the propagation of peppers on a global level have no more secrets. An international team of researchers (among the Italian participants also Enea and the University of Turin), led by Pasquale Tripodi (Crea's horticulture and horticulture research center) and Nils Stein (German Leibniz Institute for plant genetics and crop research ), has reconstructed its genetic history to discover how much culinary tastes and food traditions have conditioned the biodiversity and the spread of this product, drawing valuable scientific and agronomic information for the future. I study Conducted as part of G2P-SOL, the largest European research project Horizon 2020 on the Solanaceae family, coordinated by Enea, it has just been published in the prestigious journal of the American Academy of Sciences (PNAS). Scientists have analyzed over ten thousand samples of species of the genus Capsicum kept in international germplasm banks: this is the largest collection in pepper so ...
