Now accepted for publication in the New Phytologist! Stay tuned for the final, and in our opinion improved version, on the journal homepage! Big congrats to co-first authors @panazerv.bsky.social & @zopos.bsky.social and all coauthors! #Linum #supergene #distyly #heterostyly
Top: Topology weightings across chr15 showing how the karamu haplotype is related to the klugii and orientis haplotypes. Upper panel shows three possible rooted genealogical topologies. Second panel shows weights for each topology along the chromosome, smoothed with a 20 kb span. Arrows above the plot indicate the locations of inversions. Third panel shows unsmoothed topology weightings across a 1.5 Mb region corresponding to Inversion 2. Bottom: Ancestry painting across a 100 kb region within Inversion 2, showing ancestry tracts for two homozygous karamu individuals compared to two representative individuals homozygous for the orientis and klugii haplotypes. Coding regions are indicated below the plot, with the candidate gene for background colouration yellow indicated. Green triangles represent the top 10 SNPs for background colour in our GWAS. There is evidence for recombination throughout the supergene region, and specifically in the vicinity of yellow, consistent with the hypothesis that orientis ancestry at this locus (i.e., the B allele) is associated with darker colouration in karamu individuals.
