Anaerobic stress
Reduced ATP caused SEL to increase
from 1 kDa to between 5 and 10
kDa in stressed roots.
Cleland
et al.
, 1994
Hypoxia
Membrane resistance (electrical
coupling ratio), a measure of PD,
resistance unaffected.
Zhang & Tyerman, 1997
Metabolic
inhibitors
CCCP and probenicid increased
symplastic movement from
transport phloem in
Arabidopsis
roots.
Wright & Oparka, 1997
Cytochalasin, which depolymerises
actin, widened the neck of
plasmodesmata in
Nephrolepis
exaltata
.
Cytochalasin had no effect on
plasmodesmal aperture in roots of
Hordeum vulgare
and
Azolla
.
White
et al.
, 1994
Cytochalasin increased SEL in
epidermal cells of
Nicotiana
tabacum
from 1 to 20 kDa.
Ding
et al.
, 1996
Actin-binding protein profilin
increased SEL in
Nicotiana
tabacum.
Ding
et al.
, 1996
Phalloidin, which stabilises actin
filaments, inhibited cell-to-cell
movement.
