Phylogenetic affiliation of endophytic actinobacteria associated with red gum tree grown in salinity area and their plant growth promoting properties and suppression of phytopathogens, and genome data mining of selected strains.

ABSTRACT: Eucalyptus is an economic plant of Thailand that can tolerate salt and drought stress. This work aims to report on the study of biodiversity among endophytic actinobacteria isolated from Eucalyptus camaldulensis grown in saline soil, as well as their properties for promoting plant growth and inhibiting fungal pathogens in vitro. Root, twig, and leaf samples of five plants, E. camaldulensis grown in Kalasin Province, Thailand, were collected. The soil samples of each plant were collected, and soil salinity was evaluated by the electrical conductivity of a saturated soil extract (ECe). It was found that the ECe of the soil was between 4.5 and 12 dS/m, and the pH of the soil ranged between 3.9 and 5.2. Based on their morphology and 16S rRNA gene sequences, the majority of
