In this study,we isolated and molecularly identified a strain of salinity-tolerant endophyte from the stem of JUJUNCAO plant.Morphological observation and 16S rRNA molecalar identification were conducted on it,and physiological biochemical and growth promoting experiments were also carried out.The results showed that PJJ-1 was identified as a red rod-shaped bacterium belonging to the Pantoea sp.genus,which was a Gram negative bacterium.This strain possessed the growth-promoting properties such as phos-phorus solubilisation,silicate solubilisation,nitrogen fixation,and siderophore production,and has been shown to have some growth-promoting effects in potting experiments of maize and tomato.This study can pro-vide a theoretical basis for the rational cultivation and ecological management of JUJUNCAO.
