Fabales

The order Fabales Bromhead, including Leguminosae (= Fabaceae Lindl.), Polygalaceae Hoffmanns. & Link, Quillajaceae D. Don, and Surianaceae Arn., is a group that emerged from angiosperm phylogenies based on DNA sequence data (e.g. Chase et al. 1993 ; APG 2003 ). Fabales is part of eurosids I and together with Fagales, Cucurbitales, and Rosales forms the “nitrogen-fixing clade” M A Bello et al. 2009 Elusive Relationships Within Order Fabales: Phylogenetic Analyses Using matK and rbcL Sequence Data Syst Bot Li H.-L 2015 Large-scale phylogenetic analyses reveal multiple gains of actinorhizal nitrogen-fixing symbioses in angiosperms associated with climate change Sci reports 5, 14023; doi: 10.1038/srep14023
