Microbe- plant interaction as a sustainable tool for mopping up heavy metal contaminated sites.

ABSTRACT:

Background

Phytoremediation is a green technology that removes heavy metal (HM) contamination from the environment by using HM plant accumulators. Among soil microbiota, plant growth promoting bacteria (PGPR) have a role influencing the metal availability and uptake.

Methods

This current study evaluates the plant growth promoting qualities of microbial flora isolated from rhizosphere, plant roots, and marine aquatic HMs polluted environments in Alexandria through several biochemical and molecular traits. Metal contents in both collected soils and plant tissues were measured. Transcript levels of marker genes (HMA3 and HMA4) were analyzed.

Results

Three terrestrial and one aquatic site were included in this study based on the ICP-MS identification of four HMs (Zn, Cd,
