Isolation, screening and identification of Cu, Zn and Pb …
[Background] Plant growth-promoting bacteria (PGPB) have good potential in assisting phytoremediation of heavy metal pollution due to their advantages in promoting the growth and heavy metal-resistance of plants. In heavy metal-contaminated soils, indigenous PGPB can better colonize and exert their plant growth-promoting abilities. [Objective] Our aim is to isolate the …

Using a global database of 664 hyperaccumulating plants, we constructed a phylogeny of hyperaccumulating plants of As, Cd, Cu, Cr, Mn, Ni, Pb, and Zn. We evaluated the phylogenetic randomness of plants hyperaccumulating different metals by comparing the minimum number of trait-state changes across the phylogenetic tree to a null model.
