Toxicity of Cadmium in plants and strategies to reduce its effects. Case study: The tomato

Cadmium (Cd) is one of the most toxic heavy metals. Its high mobility and bioaccumulative power differentiate it from the rest of its group and motivate the interest of scientists to know its effects and interaction with plants. In the present work, a bibliographic review of the main mechanisms of entry and transport of the Cd in the plants and their toxic effects in them was carried out. Also, issues such as the defense mechanisms of plants against Cd stress and existing strategies to reduce their toxicity are addressed. Within the different crops, tomato is of special interest, because it is the most widespread vegetable in the world and has been shown to be a plant tolerant to Cd and with potential for its accumulation.
