Morphological and molecular characterization of Frankia sp. isolates from nodules of Alnus nepalensis Don.

G Ganesh1, A K Misra, C Chapelon, P Normand.   

Abstract

Nodules collected from Alnus nepalensis growing in mixed forest stands at three different sites around Shillong, were crushed in various culture media to obtain isolates of Frankia. The isolates were found to have typical Frankia morphology as revealed by the scanning electron microscope. Seedlings inoculated with isolates or crushed nodules formed nitrogen fixing nodules. Frankia specific DNA probes amplified the DNA of the tested isolate AnpUS4. Partial nucleotide sequence of the 16S rRNA gene indicated that AnpUS4 was phylogenetically distinct from all other Frankia strains characterized so far.
