Population genomics of Aosta Valley rye landraces reveals genetic structure and diversity patterns relevant for germplasm conservation

Introduction Rye (Secale cereale L.) is a cereal crop well adapted to marginal environments, where traditional populations represent valuable reservoirs of genetic diversity. In the Aosta Valley (NW Italy), several local rye populations have historically been maintained under small-scale farming systems, but their gene...

From Genebank to Field: Exploiting Italian Pepper Landraces for Breeding Through Genomic and Phenotypic Characterization

Italian sweet pepper landraces represent an important reservoir of genetic diversity, although their practical exploitation in breeding programmes remains limited. Historical germplasm collections preserve variation accumulated through centuries of farmer selection, but their organization into resources suitable for pr...

Genotype-dependent transcriptional trajectories during prolonged heat stress in Capsicum annuum L

Overall, the results suggest that genotype-dependent responses to prolonged heat exposure were associated not only with the magnitude of early transcriptional change, but also with differences in the temporal organization of stress-response, maintenance, and metabolic processes.
