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.

Article Synopsis
  • - Hybrid seed inviability (HSI) plays a crucial role in reproductive isolation, impacting speciation by varying in strength among diploid species and potentially influencing ploidy-variable species as well.
  • - The study examined HSI variation within a diploid-autotetraploid species using data from 12 population pairs across three different contact zones, focusing on the effects of crossing direction, ploidy differences, and spatial arrangement on reproductive barriers.
  • - Results revealed significant parent-of-origin effects on endosperm development and hybrid performance, indicating that these variations contribute to interploidy reproductive isolation and the overall fitness of the species, highlighting HSI as a key factor regardless of evolutionary history.

Enhancers are key players in the spatio-temporal coordination of gene expression during numerous crucial processes, including tissue differentiation across development. Characterizing the transcription factors (TFs) and genes they connect, and the molecular functions underpinned is important to better characterize developmental processes. In plants, the recent molecular characterization of enhancers revealed their capacity to activate the expression of several target genes.

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.
