Endophytic actinobacteria of a halophytic desert plant Pteropyrum olivieri: promising growth enhancers of sunflower.

ABSTRACT: In the present study, 40 actinobacterial isolates were obtained from the roots of a desert plant, Pteropyrum olivieri and tested for extracellular hydrolytic enzyme activities, hydrogen cyanide, and siderophore production. Based on these activities, three isolates designated UTMC 2482, UTMC 2483, and UTMC 3136 were selected with an aim of developing bio-fertilizing agent to improve the growth of sunflower plants under normal conditions. The selected isolates showed 98.2, 98.4, and 100% similarities in the 16S rRNA gene sequences to Streptomyces chromofuscus, Streptomyces ambofaciens, and Streptomyces gardneri, respectively. These isolates exhibited indole acetic acid production while UTMC 2483 was found to produce 1-aminocyclopropane-1-carboxylate deaminase, as
