Molecular genetic features of 5S rDNA nontranscribed spacer in Hippophae rhamnoides L.

详细

Amplification of sea buckthorn Hippophae rhamnoides L. 5S rDNA nontranscribed spacer with coding border anneal primers showed existence of a single fragment. The fragment was cloned and sequenced. It was shown that length of the Hippophae rhamnoides L. 5S rDNA nontranscribed spacer is 807 bp. Analysis of the sequence allowed to detect a high homology with early described microsatellite locuses of Hippophae rhamnoides L., russian olive Elaeagnus angustifolia L., and Calligonum mongolicum Turcz. that include a (GA)₉ motif. These results may be useful to study a ribosomal RNA gene organization.
