Physcomitrella CLEs Suppress Cell Proliferation
(A) Treatment of Physcomitrella plants with 1 μM CLV3-like CLEs from Arabidopsis and Physcomitrella, but not TDIF-like CLEs, causes gametophore and leaf stunting. The scale bar represents 100 μm.
(B) Leaf series from gametophores treated with CLEs expressed during gametophore development. The scale bar represents 1 mm.
(C) Cell outlines of half-leaves in CLE-treated gametophores (leaf 9 was used). The scale bar represents 100 μm.
(D) Height measured from ≥25 gametophores treated with CLEs (n ≥ 25; ANOVA; Tukey’s HSD; p < 0.005).
(E) Leaf 9 cell numbers in CLE-treated half-leaves (n = 3; ANOVA; Tukey’s HSD; p < 0.05).
