Willows (Salix) and poplars (Populus) are known worldwide as woody species with diverse uses. Although these two genera diverged from each other around the early Eocene, they share numerous traits, including the same chromosome number of 2n = 38 and the common ‘Salicoid’ genome duplication with a high macrosynteny. However, most willow species flower early in their lives with short, small and sometimes indistinct stems, and thus differ from poplars in their life histories and habits. In addition, multiple inter- and intrachromosomal rearrangements have been detected involving chromosomal regions present in both lineages, suggestive of the likely genomic divergence after the common genome duplication.
