It is expected that this report will prompt further screen-
ings of actinomycetes, especially NSA, as potential plant
growth promoters for use in nutrient impoverished soils (El-
Tarabily and Sivasithamparam, 2006). The isolate of M.
endolithica examined in this study, in addition to being a
native of UAE soils is most suited for seed inoculation because
of its high levels of rhizosphere competency.
