Ameliorative effect of indole-3-acetic acid- and siderophore-producing Leclercia adecarboxylata MO1 on cucumber plants under zinc stress
This study investigated the plant growth-promoting effects of Leclercia adecarboxylata MO1 for Zn stress mitigation and plant growth improvement in Zn-contaminated soil. Results demonstrated that L. adecarboxylata MO1 produced siderophores that could solubilize Zn and silicate, had a tolerance to el...
