Article Synopsis
- The study examines the relationship between genetic and phenotypic variations in European crabapple (Malus sylvestris), focusing on how these variations relate to different environmental conditions across Europe.
- Researchers analyzed growth rates and carbon uptake traits of seedlings while also assessing genetic differences through microsatellite loci and methods to understand population divergence.
- Findings revealed ongoing gene flow from domesticated apples into wild populations and significant trait variations among populations; however, historical climate adaptation played a more crucial role than current climatic isolation in shaping genetic differences.
Article Synopsis
- The study examines the genetic divergence of apples in the Caucasus and Iran, focusing on wild and cultivated varieties using 26 microsatellite markers from 550 samples.
- Researchers identified two genetically distinct cultivated apple populations in Iran, which originated from specific domestication events of Malus orientalis, diverging from the standard domesticated apple (Malus domestica).
- The findings highlight Iran's significance in apple domestication history, the role of gene flow between wild and cultivated apples, and the influence of climate change on genetic diversity, setting the stage for future conservation and breeding efforts.
In plants, local adaptation across species range is frequent. Yet, much has to be discovered on its environmental drivers, the underlying functional traits and their molecular determinants. Genome scans are popular to uncover outlier loci potentially involved in the genetic architecture of local adaptation, however links between outliers and phenotypic variation are rarely addressed.

Its evolutionary success is related to the rapid and profound genome reorganizations that allow neoallopolyploids to form and adapt. Nevertheless, how neoallopolyploid genomes adapt to regulate their expression remains poorly understood.
