Pw. Barlow, STRUCTURE AND FUNCTION AT THE ROOT APEX - PHYLOGENETIC AND ONTOGENIC PERSPECTIVES ON APICAL CELLS AND QUIESCENT CENTERS, Plant and soil, 167(1), 1994, pp. 1-16
The summit of roots of various plant species may be occupied by a sing
le, rapidly proliferating tetrahedral apical cell (as in ferns), or by
a multicellular and slowly proliferating quiescent centre (as in angi
osperms), or by intermediate types of cellular organizations. The pres
ent paper attempts to deduce the phylogeny of these various types of c
ellular patterning at the root apex.
