Abstract
Ca2+ influx and control of cytosolic-free [Ca2+] ([Ca2]i) although fundamental to stimulus-response coupling, are poorly understood in plants. We recently demonstrated in guard cells Ca2+ release triggered by a hyper-polarisation-activated Ca2+ influx, and have identified Ca2+ permeable channels at the guard-cell plasma membrane. We propose that these channels mediate in, and are crucial to [Ca2+]i changes. Funding is requested (1) to fully analyse the single-channel characteristics; (2) to relate these to the Ca2+ flux and voltage-evoked [Ca2+]i rise and (3) to examine the role for the channels in initiating [Ca2+]i-mediated signals.
