Hyperaccumulation
Web13 mei 2004 · First, the tolerance/disposal hypothesis suggested that hyperaccumulation is a mechanism that allows sequestration of metals in tissues (tolerance) and, in some cases, elimination of metals from the plant body by the shedding of those high metal tissues (disposal). A recent genetic analysis showing that Zn tolerance and Zn … WebCd-hyperaccumulation in plants requires enhanced root uptake, increased xylem loading, augmented translocation from roots to shoots, and then final sequestration into vacuoles and cell walls in shoots (Uraguchi et al., 2009, Verbruggen et al., 2009, Isaure et al., 2015).
