| Abstract: | Canavanine is a nitrogen-rich non-protein amino acid, with a supposedly dual role of food storage and defence in seeds and seedlings. It seems to be unique to Leguminosae subfamily Papilionoideae although it does not occur in all species or genera. This report extends the previous surveys for canavanine to 1200 species in 240 genera (including first records for 70 genera) and assesses the systematic and ecological significance of its distribution. |
