Other claims from this paper (6)
- Observation The primary Arabidopsis shoot apical meristem is initiated late in embryogenesis after the cotyledons.
- Mechanism SHOOT MERISTEMLESS was identified as critical for shoot meristem initiation.
- Observation Shoot meristemless mutant seedlings lack a shoot apical meristem.
- Observation The mutant seedlings were otherwise healthy and viable.
- Intervention effect The shoot meristemless-1 mutation completely blocked embryonic shoot meristem initiation.
- Mechanism Shoot meristemless tissue failed to regenerate shoots in culture, suggesting a role in adventitious meristem formation.
