Non-protein amino acid-accumulating clade

The non-protein amino acid-accumulating clade is a monophyletic clade of the flowering plant subfamily Faboideae (or Papilionoideae) that includes the majority of agriculturally-cultivated legumes. 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.[1][2][4] 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.[4] 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.[3] The clade does not currently have a node-based definition.

gollark: Is that futhark?
gollark: Natural languages are kind of terrible because they evolve randomly and turn wildly inconsistent and weird pretty fast.
gollark: Hey, I didn't say that that was a good language either.
gollark: English is kind of a terrible language. Like most languages.
gollark: Communism is way too communist for me to agree with it.
