The non-protein amino acid-accumulating clade, also known as the Canavanine-accumulating clade is a clade of the flowering plant subfamily Faboideae (or Papilionoideae) that includes the majority of agriculturally-cultivated legumes.[3][4][1] It is characterized by the accumulation of the non-proteinogenic amino acid canavanine in the seeds—a deterrent against herbivory. This phylogenetic trait was first recognized in the early 1980s.[5] This clade is consistently resolved in molecular phylogenies.[3][4][2] It contains many economically important genera, including Cicer, Glycine, Medicago, Phaseolus, Trifolium, Vicia, and Vigna.
Description
This clade circumscribes five subordinate clades: two traditional tribes (Hypocalypteae and Indigofereae) and three informal clades (the mirbelioids, the millettioids, and Hologalegina), as well as several minor taxa.[2] The name of this clade is informal and is not assumed to have any particular taxonomic rank like the names authorized by the ICBN or the ICPN.[1] The clade does not currently have a node-based definition.
