Data supporting: Chromosome-level genome of the transformable northern wattle, Acacia crassicarpa

The genus Acacia is a large group of woody legumes containing an enormous
amount of morphological diversity in leaf shape. This diversity is at
least in part the result of an innovation in leaf development where many
Acacia species are capable of developing leaves of both bifacial and
unifacial morphology. While not unique in the plant kingdom, unifaciality
is most commonly associated with monocots, and its developmental genetic
mechanisms have yet to be explored beyond this group. Here we identify an
accession of Acacia crassicarpa with high regeneration rates and isolate a
clone for genome sequencing. We generate a chromosome-level assembly of
this readily transformable clone and using comparative analyses confirm a
whole genome duplication unique to Caesalpinoid legumes. This resource
will be important for future work examining genome evolution in legumes
and the unique developmental genetic mechanisms underlying unifacial
morphogenesis in Acacia.
