... Heidstra; Yuji Kamiya; Shinichiro Sawa The root meristem (RM) is a fundamental structure that is responsible for postembryonic root growth. The RM contains the quiescent center (QC), stem cells and frequently dividing meristematic cells, in which the timing and the frequency of cell division are tightly...

... concentration or on auxin flux. Supporting this idea,NPA treatment of wild-type roots phenocopied the brx root meristem phenotype. Moreover, BRX is constitutively turned over by the proteasome pathway in the nucleus. However, a stabilized C-terminal BRX fragment significantly rescued the brx root growth...

... divisions within the root meristem. The root meristem, in turn, is laid down during embryogenesis. We have analysed six mutations causing alterations in the radial organisation of the root. Embryonic phenotypes resulting from wooden leg, gollum, pinocchio, scarecrow, shortroot and fass mutations...

... of antigen rather than a symmetrical distribution. Certain cells of the pericycle, distinctive due to a series of oblique longitudinal divisions, first discernible at 40 μ m from the most apical cells (Esau, 1940), are particularly reactive with JIM4. Serial sectioning of such a primary root meristem...
