Localization of plant meristems. Localization of plant meristems. Apical and axillary meristems (arrowheads) of (A) Arabidopsis embryo, and (B) Marchantia gametophyte, respectively. (C) Vascular meristems that generate xylem and phloem tissues during radial growth are located within a narrow ring (dashed line). (D) Lintilhac (1974a,b) showed the points of stress concentration generated by notches. He also predicted that ring-like geometries (dashed line) would be zones where forces of tension and compression nullify (E). We hypothesize that the mechanical properties of these regions are part of a potentially generic mechanism for the localization and maintenance of SCNs in multicellular organisms.
