speciation-genetics
Speciation-genetics is the study of genetic mechanisms and processes that drive the formation of new, reproductively isolated species through evolutionary change. In plant science, this field is particularly important because plants can speciate through mechanisms uncommon in animals, including polyploidy (whole genome duplication) and hybridization. Understanding these genetic pathways is essential for explaining plant diversity, predicting evolutionary outcomes, and informing conservation strategies.

Recombination suppression is a genetic mechanism that prevents genes from shuffling in certain DNA regions, allowing plants to evolve into separate species while still interbreeding. This review explains how this mechanism drives plant adaptation and speciation by linking beneficial genes together and limiting genetic exchange between populations.
Recombination suppression facilitates genomic divergence and speciation under ongoing gene flow, enabling plant populations to diverge despite continued interbreeding
Multiple genomic contexts generate recombination suppression: structural variants, transposable elements, epigenetic modifications, and centromeric regions
New long-read sequencing technologies and haplotype-resolved assemblies now enable fine-scale mapping of recombination landscapes across plant systems
