Resumen: "Globally, farmers cultivate and maintain crop landraces (i.e., traditional varieties).Landraces contain unique diversity shaped in part by natural and human-mediatedselection and are an indispensable resource for farmers. Since environmental conditionschange with elevation, crop landraces grown along elevational gradients haveprovided ideal locations to explore patterns of local adaptation. To further probetraits underlying this differentiation, transcriptome signatures can help provide afoundation for understanding the ways in which functional genetic diversity maybe shaped by environment. In this study, we returned to an elevational gradient inChiapas, Mexico, to assess transcriptional differentiation of genes underlying UV-Bprotection in locally adapted maize landraces from multiple elevations. We collectedand planted landraces from three elevational zones (lowland, approximately 600 m"
