Abstract

Acetylcholine was first found in a fungus, from there was found in bacteria, animals and plants. Both its synthesizing enzyme and the degrading are also found in plants. Although it lacks a clearly defined role in plants, it has been suggested that acetylcholine is a secondary messenger in various cellular processes such as action of phytochrome, leaf movements, ionic permeability of membranes, among others. This study aims to evaluate the role of acetylcholine in the transduction of signals between roots and shoots of maize seedlings under water stress conditions. Therefore, corn seedlings will be grown in laboratory conditions and subjected to water stress. Then, acetylcholine will be extracted and stomatal conductance will be measured. Studies will be conducted at the Laboratório de Fisiologia de Plantas sob Condições de Estresse da Escola Superior de Agricultura Luiz de Queiroz / USP. (AU)
