Biotechnological Implication with Azolla pinnata R.Br. for Metal Quenching Ability with Physiological Biomarkers.

Abstract

<p>The present paper holds the accountability of an aquatic fern R.Br. for biotechnological implication. Azolla pinnata In an artificial<br />laboratory condition Azolla plants responded well in hyper accumulation of lead in a concentration dependent manner however, within a<br />threshold value. In accompany with metal bioaccumulation plants responded a regulated growth performances with relative growth rate<br />(RGR) and net assimilation rate (NAR). The plants responded well with a chemical elicitors like polyamine in response to metal<br />quenching ability. At the cellular level the phytotoxicity of the plant is mitigated by both non-enzymatic and enzymatic cascades. It is an<br />advantage of the plants to down regulate reactive oxygen species (ROS) - superoxide (O ) and peroxide (H O ) in a moderate level as 2 2 2<br />-<br />compare to higher plants and modulated with polyamine. The diversity in this species was also recorded for few gene expression related to<br />antioxidation. Fern under lead toxicity displayed well in protein polymorphism for peroxides with variations. The responses of this<br />species for metal hyper accumulation and over expressed physiological traits are discussed in light of phytoremidiation.<br />Keywords: Azolla; Heavy Metals; Oxidative Stress; Antioxidative enzymes; Polyamine</p><p> </p><p><span>DOI: </span><a id="pub-id::doi" href="http://dx.doi.org/10.21756/cba.v1i1.10960">http://dx.doi.org/10.21756/cba.v1i1.10960</a></p>
