Abstract: Water channels have been ubiquitously found in plants and play important roles in plant growth and development because they can specifically promote the transportation of water across the membrane. Based on the advances in research into plant water channels, this article discusses mainly the eco-physiological characters of plant water channels and their involvement in stomatal movements, with the conclusion that water channels may play important roles in stomatal oscillation.

Key words: Plant water channel, Eco-physiological character, Stomatal movement, Stomatal oscillation
