In this thesis, we made a bioinformatics analysis of articles published over the last ten years on the production and/or function of NO in plant responses to heavy metals, including Cd. This analysis showed that exogenous applications of NO to the plant protect against heavy metals, particularly Cd, and that, in response to exposure to heavy metals, particularly Cd, plants initially produce NO, which can act as a signal molecule. At a later stage, the plant appears to be equipped with mechanisms to control NO levels, thus preventing further symptoms of toxicity. Using both biochemical techniques, involving modifications in NO levels through chemical donors and scavengers, and molecular approaches, involving the use of mutants with al...
