ALLELIC VARIANTS OF WAXY GENES IN TRITICUM AESTIVUM L. CULTIVARS GROWN IN THE PERM REGION AND BASHKIRIA
Molecular marker-based identification of allelic variants of Waxy genes has been performed in a collection of 30 common wheat varieties grown in the Perm region and Bashkiria. Genotyping with two molecular marker sets shows that all these cultivars bear the wild-type allele of the Wx-A1 gene; cvs. Bashkirskaya 4, Bashkirskaya 26, and âBashkirskaya 28 possess the functional allele of the Wx-B1 gene, Wx-B1e; and Ulâyanovskaya 100 is heterozygous, possessing Wx-B1Đ° and Wx-B1e. No varieties with null-alleles of Wx-B1 have been found. Only wild-type alleles are present in the Wx-D1 locus
Molecular genetic identification of Scots pine and Siberian larch populations in Perm Krai based on polymorphism of ISSR-PCR markers
The use of DNA-fingerprinting of forest-forming woody plants is considered the most promising tool for genetic control of woodâs geographic origin, the formation of a reliable management system for harvesting and turnover of lumber. The purpose of this work was to search for identification markers, genotyping trees, and molecular genetic identification of previously not studied 2 populations of the Siberian larch Larix sibirica Ledeb. and 4 populations of Scots pine Pinus sylvestris L. of different regions of the Perm Krai. To DNA extraction, from each plant specimens wood were individually obtained and a modified method of extracting DNA from wood was used. In total, the analysis used the DNA of 114 Scots pine trees and 55 Siberian larch trees. For genetic testing, we used ISSR (Inter Simple Sequence Repeats)-method of DNA polymorphism analysis. Genetic identification was performed based on the original authorâs method proposed by S. V. Boronnikova and I. V. Boboshina (2014). As a result of molecular genetic analysis, 74 ISSR markers were found and analyzed in populations of Scots pine, 85 ISSR markers were identified in populations of the Siberian larch, and the share of polymorphic loci in both species was high. As a result of molecular genetic identification, identification of species and polymorphic ISSR-markers and their combinations were found that characterize the belonging of trees to a species, as well as to a specific population. Molecular genetic formulas and barcodes for each individual population of two species have been compiled. The effectiveness, stability, and reproducibility of detected identification markers and their combinations have been proven through anonymous testing. The data obtained are the basis for determining the place of origin of wood, which will allow us to recommend measures to counter illegal logging and reduce the damage to the budget of logging regions of Russia, such as the Perm Krai
