Fig. 7

Immunogold micrographs of pectate lyase pretreated transverse sections of celery collenchyma strands at different developmental stages labelled with monoclonal antibodies LM15 (a-h), LM21 (i) and LM11 (j-m). Stage 1 (2.6 cm long petiole) (a, b), Stage 2 (11 cm petiole) (c, d, i), Stage 3 (24 cm petiole) (e, f, j, k), Stage 4 (40 cm petiole) (g, h, l, m). Two different regions of cells were shown, cell corners (a, c, e, g, I, j, l) and thick walls (b, d, f, h, k, m) that connect two cells, mj = middle lamella junctions, ml = middle lamella, pm = plasma membrane. Scale = 500 nm
