Lead accumulation in the roots of grass pea (Lathyrus sativus L.): a novel plant for phytoremediation systems?

Decontamination of Lead from aquatic environment by exploitation of floating macrophyte Azolla microphylla Kauf

“…However, Pb treatment at 100mg/l concentration showed toxicity symptoms like chlorosis and drying of edges in plants. Similar response to lead treatment was previously noticed in various plants [30] [31] . Decreased plant growth might be associated with the inhibition of mitotic index noticed with Pb and Cd heavy metal treatment [32] .…”

“…Relative water content in leaves was slightly higher in Pb treated plants than in the control at the end of the treatment. It is most likely that Pb treatment induced stomatal closure, triggered over the course of the experiment due to the atmospheric carbon fixing activities that were compromised as a consequence (Brunet et al, 2008). (The results presented are the means of three replicates)…”

“…The possibility that this environmental tolerance is linked to the presence of the neuro-excitatory amino acid -ODAP ( -N-oxalyl-, -diaminopropionic acid) cannot be ruled out. This unusual amino acid is a good chelator for copper and zinc and may play a role in phytoremediation (Brunet et al, 2008). The alternative strategy could be to introduce the biosynthetic pathway for genistein into legumes more tolerant to environmental stress.…”

Phytoremediation - A sustainable approach for contaminant remediation in arid and semi-arid regions ? a review

“…Grass pea (Lathyrus sativus L.), a ubiquitous annual leguminous crop, which can thrive in poor soils, and in very arid environments was observed to accumulate Pb in its root tissues, with impact on the mineral homeostasis for Ca, Cu and Zn, though (Brunet et al, 2009 (Badr et al, 2012). They found that Phragmites australis and Cyperus laevigatus were found to be the best candidates for biomonitoring and phytoremediation programs of metal-polluted soils (Badr et al, 2012).…”
