Editing L-DOPA (section)

=== Plants and in the environment ===
In plants, <small>L</small>-DOPA functions as an [[allelochemical]] which inhibits the growth of certain species, and is produced and secreted by a few legume species such as the broad bean ''[[Vicia faba]]'' and the velvet bean ''[[Mucuna pruriens]]''.<ref>{{cite journal | vauthors = Fujii Y, Shibuya T, Yasuda T| title = L-3,4-Dihydroxyphenylalanine as an Allelochemical Candidate from Mucuna pruriens (L.)
