金合欢属是一大类木本豆科植物，在叶形上具有大量的形态多样性。这种多样性至少部分是叶片发育创新的结果，许多金合欢物种能够发育双面和单面形态的叶片。虽然在植物界不是唯一的，但单一性最常与单子叶植物有关，其发育遗传机制尚未在这一群体之外进行探索。在这项研究中，我们鉴定了一株再生率高的甘薯，并分离了一个克隆进行了基因组测序。我们产生了一个染色体水平的组装，这个容易转化的克隆，并使用比较分析，确认全基因组复制独特的凯撒类豆科植物。这一资源将对未来研究豆科植物基因组进化和金合欢单面形态发生的独特发育遗传机制具有重要意义。
The genusAcaciais 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 manyAcaciaspecies are capable of developing leaves of both bifacial and unifacial morphologies. 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. In this study, we identify an accession ofAcacia crassicarpawith 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 inAcacia.
