    • Arachis pintoi as a possible hyperaccumulator plant of heavy metals. Zuleika Velázquez Ortiz University of Puerto Rico at Cayey Rise Program 2012Summary plant and the ground by atomic absorption to complete within thirty days. Through the following investigationit intends to analyze the plant Arachis pintoi Introductionto determine if it could be suitable to absorb Hyperaccumulator plants have theheavy metals in contaminated sites. Carrying ability to develop biological mechanismsout the proposal with a perspective to know that allow it them to survive in soils rich inif could get a new hyperaccumulator plant metals. Some of these plants are being usedpossessing in its genome the to carry out phytoremediation. Process usedMetallothionein protein, a protein-coding for as a treatment in contaminated environmentsthe absorption of metals with which could through which plants absorb pollutants. Fordevelop the phytoremediation, these plants to carry out thedecontamination process of places with the phytoremediation of heavy metals, theyuse of plants. It questioned as follows; Does must possess in their genome the genethe plant Arachis pintoi have the ability to encoding Metallothionein protein. This is aabsorb heavy metals? Subsequent to the protein that binds mineral ions in organicquestion was made the possible answer; if nature with a high content of cysteine, whichthe Arachis pintoi have the ability of absorb allows the absorption of heavy metals foundmetals, it will be able to carry out in contaminated soil, water and airphytorremediation. It set four positive contamination. Thus the purpose of thisgroups with four different metals; research is to determine if the plant ArachisAluminum, Copper, Lead and Mercury, and pintoi, which is able to develop quicklyone negative group owner of any change. (creeping) and adapt to drought being aThese groups will be areas of land with a plant of wet places, has Metallothioneinmeasure of 4’x4’, all with the Arachis pintoi protein and therefore the ability to absorbplant. It will make a weekly analysis of the metals.
