Characterisation of endophytic bacteria from a desert plant lepidium perfoliatum L.

Abstract

Li Y., Cheng C., An D. (2017): Characterisation of endophytic bacteria from a desert plant Lepidium perfoliatum L. Plant Protect. Sci., 53: 32–43. Sixty-two endophytic bacteria from the leaves, roots, and stems of healthy Lepidium perfoliatum L. were isolated and characterised. From the results, 89, 87, 90, and 97% isolates could tolerate 12% NaCl, 30% PEG 6000, 50°C and pH 10, respectively. 74% isolates could form a biofilm. Besides, 28 isolates could improve the germination rate of host seeds under different degree of drought stress. These data suggest that the endophyte isolates show considerable resistance to abiotic stress and assist their plant hosts to germinate under drought stress.
