Other claims from this paper (13)
- Observation The Arabidopsis ncp2 mutant lacked cotyledons in seedlings and embryos in the pid background.
- Observation Arabidopsis NCP2 encodes RHD4/SAC7 phosphoinositide phosphatase.
- Observation SAC6, SAC7 and SAC8 show overlapping and specific expression patterns in Arabidopsis seedlings and embryos.
- Observation Embryo development is significantly delayed or lethal in Arabidopsis sac7 sac8 mutants.
- Observation Embryo development is significantly delayed or lethal in Arabidopsis sac6 sac7 sac8 mutants.
- Observation Arabidopsis sac7 sac8 seedlings are arrested early.
- Observation Arabidopsis sac6 sac7 sac8 seedlings are arrested early.
- Observation Auxin maxima decrease in Arabidopsis double sac mutants.
- Observation Auxin maxima decrease in Arabidopsis triple sac mutants.
- Observation PtdIns4P and PtdIns(4,5)P2 contents dramatically increase in Arabidopsis sac6 sac7 mutants.
- Observation PtdIns4P and PtdIns(4,5)P2 contents dramatically increase in Arabidopsis sac7 sac8 mutants.
- Observation PIN1 and PIN2 trafficking from the trans-Golgi network/early endosome back to the plasma membrane is delayed in Arabidopsis sac7 sac8 mutants.
- Mechanism SAC6-SAC8 are essential for phosphoinositide homeostasis and auxin-mediated Arabidopsis development.
