Other claims from this paper (7)
- Observation The Arabidopsis tps1 mutant is recessive embryo lethal.
- Observation TPS1 is transiently up-regulated during early cell expansion and storage reserve accumulation.
- Mechanism TPS1 is needed for full expression of seed maturation marker genes 2S2 and OLEOSN2.
- Observation Seed sucrose levels rise rapidly at the onset of cell expansion.
- Intervention effect Reducing sucrose partially rescues Arabidopsis tps1-1 embryo growth in vitro.
- Observation T-6-P does not inhibit AtHXK1 or AtHXK2.
- Intervention effect Reducing hexokinase activity does not rescue tps1-1 embryo growth.
