Analysis of intraspecific polymorphism of Nitraria sibirica Pall. using the ISSR technique

Abstract

The analysis of DNA polymorphism of Nitraria sibirica Pall. was carried out at 13 natural populations of the Republic of Altai and Altai Territory using the ISSR technique. Seven effective ISSR primers have been identified to analyze DNA polymorphism in N. sibirica. 99 DNA fragments were yielded at DNA amplification with these primers, 66 of them were polymorphic. The genetic distance Nei (D) between the studied populations of N. sibirica averaged 0.32, at mean 0.09 - within populations. An identification ISSR marker has been revealed, which can be used to study the genetic variability of the genus Nitraria L. (Nitrariaceae) species.
