(2022-06-08) – New News & Views in Nature

Genome sequences of multiple wild potato species and landraces hold promise for developing improved varieties of an important food crop. Juanita and Tanja wrote a short Nature News & Views piece about Tang and colleagues’ new paper on genome evolution and diversity of wild potatoes, highlighting how genomic resources can aid development of new varieties of this important food crop. Both the paper and our News & Views piece are out today!

(2022-05-29) – New preprint on the Linum distyly supergene up on bioRxiv

Our new preprint entitled “Genomic analyses of the Linum distyly supergene reveal convergent evolution at the molecular level” is now up on bioRxiv.

In this study, we present a chromosome-scale genome assembly of the distylous species Linum tenue, and use population genomic data to identify the distyly supergene. We show that hemizygosity and thrum-specific expression of S-linked genes, including a pistil-expressed candidate gene for style length, are major features of the Linum distyly S-locus supergene. We find a striking resemblance between the independently evolved Linum and Primula distyly supergenes in terms of genetic architecture, molecular evolution, and the assembly of the gene set at the supergene.
