Somestudies also dealtwith uraniumspeciation in plants. Themajor
form of uraniumin plant tissues of Lupinus spp.was phosphate complex
(Gunther et al., 2003). This result was confirmed later (Laurette et al.,
2012). Uranium complexation with phosphates led to its precipitation
and fixation in plant organs of Brassica napus and H. annuus. Moreover,
it was shown that complexation with citrate enhanced translocation of
uranium in the shoots into carboxylate complex form (Laurette et al.,
2012).
