The application of Brdička reaction for determination of phytochelatins in real samples of barley and thermophilic cyanobacterium grown in the presence of cadmium ions
 Čížková, Petra ; Fedjuk, K. ; Šestáková, Ivana
Heavy metals represent important group of environmental contaminants. Ions of heavy metals (Cd, Pd, Cu, Hg, Zn and Ni) are released into soil solutions as a consequence of soils acidification, among others. Their presence has imminent influence on physiological procedures in plants, which have developed different mechanisms of adaptation on such conditions. One of mechanisms for plants tolerance towards heavy metal ions is their inactivation by binding on polypeptides or small proteins with high cysteine content, named phytochelatins (PC) or metallothioneins. Their function has been studied in particular at man and animals.
