Pan-family pollen signals control an interspecific stigma barrier across Brassicaceae species
Abstract Pre-zygotic interspecific incompatibility prevents hybridization between species limiting interbreeding strategies for crop improvement using wild relatives. The Brassica rapa female self-incompatibility determinant, S-locus receptor kinase (SRK), recognizes interspecific pollen. Here we report the discovery of a pan-Brassicaceae SRK-interacting Interspecific Pollen Signal (SIPS). On B.
Large-scale gene expression alterations introduced by structural variation drive morphotype diversification in Brassica oleracea - Nature Genetics
Abstract Brassica oleracea, globally cultivated for its vegetable crops, consists of very diverse morphotypes, characterized by specialized enlarged organs as harvested products. This makes B. oleracea an ideal model for studying rapid evolution and domestication. We constructed a B. oleracea pan-genome from 27 high-quality genomes representing all morphotypes and their wild relatives. We identified structural variations (SVs) among these genomes and characterized these in 704 B.
Variations in Homoeologous Dosage and Epigenomics Mark the Early Evolution of Synthetic Brassica Tetraploids
New Results doi: https://doi.org/10.1101/2023.06.27.543697 Abstract Polyploidization is important in plant evolution and is becoming increasingly important in crop breeding and material creation. Studies have provided evidence for structural variations and epigenomic repatterning in synthetic polyploidizations, but the relationships between structural and epigenomic variations, as well as their effects on gene expression and phenotypic variations are unknown.
