Abstract
Zinc (Zn) contamination in soil has been a serious problem world widely. Plant growth-promoting bacterium (PGPB) could have potential applications in Zn bioremediation. In this study, Burkholderia pyrrocinia strain JK-SH007 had a high tolerance to Zn and was able to produce indole acetic acid and siderophore, to solubilize inorganic phosphate. And it was found to promote tomato growth and tolerate to high concentration of Zn. We employed a novel combination of transmission electron microscopy (TEM) and scanning electron microscopy with electron dispersive X-ray analysis (SEM-EDX) for understanding the mechanism of Zn toxicity on plant tip morphology, ultrastructure and bacterium protection tomato cell. The high Zn soil supplement was highly toxic to the plants, biomass decreased, root growth inhibited, shoots rotted and chlorisis induced. ‘JK-SH007ʹ improved the relative tolerance of tomato to Zn, enhanced Zn sequestration, alleviated the associated plant damage relative to PGPB-free controls. ‘JK-SH007ʹ may be used to assist metal-hyperaccumulating plants in bioremediation.
