Root development: new meanings for root canals?
During Arabidopsis root development, a radial pattern of tissues is extended by the meristem. These tissues form continuous layers and recent data suggest that tissue continuity is instrumental for constraining the direction of signaling in a process termed channeling. In the ground tissue, fate-determining signals originate from contiguous cells of the same layer, possibly due to specific symp...
متن کاملRoot patterning: SHORT ROOT on the move
The radial pattern of the plant root is determined by the action of two transcription factors, SHORT ROOT and SCARECROW, which are produced in different cell types. The SHORT ROOT protein has now been shown to move from cell to cell, regulating transcription of the downstream SCARECROW gene in the target cells.
متن کاملRoot canal posts for the restoration of root filled teeth.
BACKGROUND The foundation for the reconstruction of endodontically-treated teeth can be provided by a metal or a non-metal post and core system but no guidelines exist for choosing one or the other in particular clinical cases. OBJECTIVES To assess the effectiveness of different post and core systems for the restoration of endodontically-treated teeth. The primary objective of this review was...
