First Report of the Hyperaccumulating Potential of Cadmium and Lead by Cleome rutidosperma DC. With a Brief Insight Into the Chemical Vocabulary of its Roots

Phytoremediation is gaining interest in recent years as it a simple and effective strategy for heavy metal decontamination. The most straightforward successful clean-up searching efficient hyperaccumulator species that grow naturally contaminated sites. present study, therefore, the first detailed account of potentialities neglected underutilized (NUS) species, Cleome rutidosperma DC . Hydroponic screening experiment against cadmium lead revealed even at 10 mg/kg concentration, could accumulate 42.49 Cd 27.79 Pb shoots, while 134.71 491.35 its roots, these values were significantly higher than those control plants. This plant efficiently high 639.07 Cd, 8,726.03 752.83 3,732.64 shoots evident from pot experiments. In case there was no significant effect toxicity on phytophysiological parameters. But increasing concentrations did have toxic effects total chlorophyll content. showed to BCF >1 tested concentrations. At highest treatment however, both TF found be greater 1. indicated C. can translocate metals aerial parts when concentration extremely high, proving itself an hyperaccumulator. order decode chemical signals, this may emit through roots cope with stress; root exudates collected, purified, analyzed GCMS. presence five major compounds, namely, palmitic acid, linoleic oleic campesterol, stigmasterol, which mainly are metabolic markers detoxification mechanisms triggered by various stresses. Therefore, based termed potent further exploited remediation other classes environmental pollutants.
