Rat Natriuretic Peptide Binds Specifically to Plant Membranes and Induces Stomatal Opening

摘要: Abstract Stomatal aperture changes modulate the rate of transpiration and gas exchange in plants. High cellular turgor guard cell pair due to water solute influx leads stomatal opening, whereas closing is caused by reduction efflux. This process controlled plant hormones. We demonstrate that a vertebrate peptide hormone, rat atrial natriuretic (rANP), induces opening Tradescantia sp. concentration dependent manner provide evidence rANP affects amiloride sensitive Na + /H channel.
