What is it about?
Our research offers a pioneering analysis of the London planetree's genome, uncovering its unique ancient hexaploid nature and remarkable karyotypic stasis despite two whole-genome duplications. Our research also understands the genetic basis of its biennial flowering cycle and the role sub-/neo-functionalization plays in its genome.

Why is it important?
Our findings show the karyotypic stasis of Platanus despite two rounds of whole-genome duplication. The Platanus species has the chromosome karyotype most similar to AEK among existing species. Our research provides an important research case for studying the role of genome shuffling and gene sub-/-neofunctionalization in the process of polyploid diploidization.
