Other claims from this paper (13)
- Observation Vicia species can be subdivided into groups characterized by associations of ninhydrin-positive compounds in high concentrations in their seeds.
- Observation Canavanine is a major constituent in the seeds of 17 Vicia species.
- Observation gamma-Hydroxyarginine, an amino acid not found in other plant genera, occurs in 18 Vicia species.
- Observation gamma-Hydroxyornithine, a new natural amino acid, is found in two Vicia species.
- Observation A new naturally occurring ureido amino acid, tentatively identified as gamma-hydroxycitrulline, is found in two Vicia species.
- Observation High concentrations of alphabeta-diaminopropionic acid are found in seed of V. baicalensis.
- Observation alphagamma-Diaminobutyric acid is found in high concentration in seed of V. aurantica.
- Observation The neurotoxic amino acid beta-cyanoalanine and its gamma-glutamyl peptide are found together in high concentrations in the seeds of 16 Vicia species.
- Observation Seven unidentified ninhydrin-positive compounds occur in high concentration, about 1% of the dry weight or more, in seed of various Vicia species.
- Observation The total concentration of extractable ninhydrin-positive compounds varies little between seeds of different Vicia species.
- Mechanism The ninhydrin-positive compounds may constitute a readily available form of storage nitrogen, as suggested for those in Lathyrus.
- Observation The nature and distribution of amino acids and related compounds accumulated in Vicia seeds differ from those in seeds of the related genus Lathyrus.
- Observation Vicia accumulates C(6) guanidino amino acids (arginine and gamma-hydroxyarginine).
