Phenotypic and Genetic data for "Evolution of fruit and seed traits during almond naturalization"

Conversely, the recessive allele sk responsible for seed toxicity was significantly more frequent in feral populations. Phenotypic differentiation between cultivated and naturalized almond populations was also significant. Feral almond kernels were smaller and lighter, had denser and more resistant shells (endocarps) and more toxic seeds.

Selection analyses indicated that these genetic and phenotypic patterns might be driven by directional selection on fruit and seed traits, potentially linked to defense against predation. 4- Synthesis. Our findings indicate that almond naturalization is consistent with strong directional selection on fruits and seeds, leading to smaller and more toxic seeds encased in harder endocarps. Accordingly, we propose that feralization of this crop is, at least to some degree, driven by adaptive evolution of dispersal and recruitment traits. | Usage note indicated in the Readme file (README.txt) Funding provided by: Ministerio de Economía, Industria y Competitividad, Gobierno de EspañaCrossref Funder Registry ID: dx.doi.org/10.13039/501100010198Award Number: CGL2016-79950-R Funding provided by: Junta de AndalucíaCrossref Funder Registry ID: dx.doi.org/10.13039/501100011011Award Number: P18-RTJ-4704
