dTat-Sar-EED4 induces
the formation of plasma membrane protrusions
and a large intracellular vesicle in plant cells. (A,B) Formation
of plasma membrane protrusions (A) and a large intracellular vesicle
(B) observed in TEM images of high-pressure frozen A. thaliana root epidermal cells after treatment with 30 μM dTat-Sar-EED4
for 15 min. Yellow arrowheads in (A) indicate plasma membrane protrusions,
while those in (B) represent intracellular vesicles (>200 nm in
diameter).
(C) Formation of membrane invaginations detected in TEM images of
high-pressure frozen root epidermal cells after treatment with 30
μM dTat-Sar-EED4 or water for 15 min. Yellow arrowheads indicate
the membrane invagination. CW, cell wall; PM, plasma membrane; Cy,
cytoplasm.
