Y. Okazaki et al., A pulse of blue light induces a transient increase in activity of apoplastic K+ in laminar pulvinus of Phaseolus vulgaris L., PLANT CEL P, 41(2), 2000, pp. 230-233
A pulse of blue light induced both a transient increase in activity of apop
lastic K+ and membrane depolarization in laminar pulvinus of Phaseolus vulg
aris L. This shows that blue-light-induced net efflux of K+ from motor cell
s is closely related to membrane depolarization.
