Assessment of the genetic diversity of Frankia microsymbionts of Elaeagnus angustifolia L. plants growing in a Tunisian date-palm oasis by analysis of PCR amplified nifD-K intergenic spacer.

Abstract excerpt

Diversity of Frankia microsymbionts of non-native Elaeagnus angustifolia L. plants spontaneously growing in a Tunisian desertic retreat area, the date-palm oasis of Tozeur, was investigated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and PCR-sequencing techniques targeting the nifD-K intergenic spacer. Three PCR-RFLP haplotypes (I, II, and III) were detected among collected...
