From: The cytological changes of tobacco zygote and proembryo cells induced by beta-glucosyl Yariv reagent suggest the involvement of arabinogalactan proteins in cell division and cell plate formation

Figure 1

Cell division pattern of zygote and proembryo in tobacco. (A1-H1) Bright-field images. (A2-H2) Fluorescence images of DAPI-stained nuclei corresponding to bright-field images. (A 1 and A 2 ) A isolated live zygote at 84 h after pollination. (B 1 and B 2 ) A two-celled proembryo with a small apical cell and a large basal cell from a zygote asymmetrical division. (C 1 and C 2 ) A three-celled proembryo with a large basal cell and two-celled embryo-proper after apical cell division. (D 1 and D 2 ) A four-celled proembryo with a two-celled embryo-proper and a two-celled suspensor. (E 1 and E 2 ) A proembryo with an eight-celled embryo-proper and a two-celled suspensor. (F 1 and F 2 ) A multicellular proembryo with a four-celled suspensor. The inserted pictures in A 2 -F 2 are schematic diagrams of zygotes and proembryos. Bars = 10 μm.
