Other claims from this paper (11)
- Intervention effect TDZ converted rhizoid-tip cell fate and triggered PLB formation and plantlet regeneration.
- Intervention effect Auxin and a Z-type cytokinin accumulated in callus-rhizoids after TDZ application.
- Observation TDZ repressed RcPIN1 transcription in callus-rhizoids.
- Observation RcARF4, RcRR1, RcCKX2, RcCKX3 and RcLOG1 expression increased in callus-rhizoids and rhizoid tips.
- Observation RcARF1, RcPIN2 and RcPIN3 transcription decreased in callus-rhizoids.
- Observation RcARF1, RcPIN2 and RcPIN3 transcription increased in rhizoid tips.
- Mechanism RcWUS and RcSERK1 were highly expressed in columella and root stem cells, associated with cell-fate conversion.
- Observation RcWUS overexpression was repressed in transgenic XVE::RcWUS lines.
- Observation RcWUS had no effect on PLB morphogenesis.
- Mechanism Higher RcWOX5, RcPLT1 and RcPLT2 expression indicated a dedifferentiation pathway in the rhizoid stem-cell niche.
- Observation Different rhizoid-tip cells acquired regeneration competence following TDZ induction.
