Epichloe endophyte interacts with saline-alkali stress to alter root phosphorus-solubilizing fungal and bacterial communities in tall fescue.

ABSTRACT: Epichloë endophytes, present in aboveground tissues, modify belowground microbial community. This study was conducted to investigate endophyte (Epichloë coenophialum) associated with tall fescue (Lolium arundinaceum) interacted with an altered saline-alkali stress (0, 200 and 400 mmol/l) to affect the belowground phosphorus solubilizing microorganisms including phosphorus solubilizing fungi (PSF) and bacteria (PSB). We found that a significant interaction between E. coenophialum and saline-alkali stress occurred in the diversity and composition of PSF in tall fescue roots. Under saline-alkali stress conditions (200 and 400 mmol/l), E. coenophialum significantly increased the PSF diversity and altered its composition in the roots, decreasing the relative a
