Other claims from this paper (11)
- Mechanism Lower seed vicine and convicine in MTG5 came mainly from reduced cotyledon glucopyranosides.
- Observation Embryo axis glucopyranoside amount was much less affected in MTG5.
- Observation Vicine rose in stems and roots of both species at days four to seven, then declined.
- Observation Convicine continued to rise in roots of both species.
- Mechanism The rise in V. narbonensis root convicine could not be explained by conversion of vicine reserves.
- Observation MTG5 initially had less vicine in stems and roots than Troy and V. narbonensis.
- Observation By day 17, MTG5 vicine approached Troy levels and exceeded V. narbonensis.
- Observation At flowering, MTG5 and Troy had similar vicine and convicine amounts.
- Observation MTG5 roots had more vicine and convicine than the sown seed.
- Observation Both Vicia species can synthesize vicine and convicine in young plants.
- Mechanism The seed glucopyranoside mutation does not suppress young plant biosynthesis.
