Secondary

IP

inhibited cell-to-cell
transport in
Setcreasea purpurea
,
by releasing Ca
2
+
from internal
stores into the cytosol via inositol
triphosphate-sensitive channels.

Boss, 1996
Elevated cytosolic Ca

decreased
PD permeability in
Egeria densa
leaves.

restricts dye
movement in soybean microcallus
cells.
Baron-Epel

No effect of Ca

on PD
permeability in the green alga
Chara
.
Reid & Overall, 1992
Free Ca
2
+
injected into cytosol
transiently closed PD of maize
cells increasing electrical
resistance between cells.

Cytoplasmic increases in other group
II ions, e.g. Mg
2
+
and Sr
2
+
,
decrease PD permeability.

High level of cytosolic Ca

stopped
dye movement in
Setcreasea
purpurea
cells.
