Polyploidy is a major driver of evolution in plants. Angiosperms have undergone several polyploidization events in their evolutionary history and the formation of neopolyploids is an ongoing process. Polyploidy is an important factor for speciation and diversification of flowering plants. However, the processes of evolutionary origin, establishment, speciation, and post-origin evolution of polyploid plants are still not well understood. Evolutionary origin is often connected to hybridization and reticulate evolution, which still presents a methodical challenge. The consequences of polyploidization on genome evolution are dramatic, involving cytological, gene composition and expression, and epigenetic effects, and potentially affects many traits of physiology, gene expression, stress response, phenotypic plasticity, reproductive biology, and ecology. While research places a strong focus on polyploid crops, the vast majority of natural polyploids are still not investigated. For many genera, not even cytotype diversity has been explored in natural populations.

Here, we propose a Research Topic on the evolution of polyploid plants in the wild. We welcome papers on evolutionary origin, establishment, genome evolution, cytotype diversity, genome size dynamics, phenotypic traits, and speciation and diversification of polyploids. Methodical approaches can include phylogenetic and phylogenomic approaches, population genomics, epigenetics and epigenomics, experimental work, flow cytometric and other karyological analyses, and studies on physiology, phenotype, reproductive biology, flower biology, and ecology of polyploids. We also welcome novel analysis pipelines for polyploids for next-generation sequencing data. We will focus on non-model organisms and plants growing in the wild; papers on crops will be considered out of scope of this Research Topic Original Research papers should be hypothesis-driven and characterized by novelty and high scientific quality. We also welcome timely Review articles related to the topic.

Submissions are sought from, but not limited to, the delegates from the Polyploidy conference in Gent (2019).
