E-mail: delarosa@quijote.ugto.mx © Universidad De La Salle Bajío (México) Insights into the mechanisms of Cd hyperaccumulation in tumbleweed, a desert plant species Abstract Tumbleweed (S.
kali), a desert plant worldwide distributed, has been proposed as a potential Cdhyperaccumulator.
X-ray studies showed that thiol and oxygen related compounds are involved in Cd sequestration within the plant.
Thus, we have proposed that organic acids, cell wall, phytochelatins, and other glutathione related compounds might be involved in the mechanisms of Cd hyperaccumulation in tumbleweed.
In this study, native plants were used to determine C...
