Genetic diversity and gene-pool of Aegilops tauschii Coss. (Poaceae) based on retrotransposon-based markers

Abstract

Genetic variation is an essential feature of biological variety for conservation methods, particularly for scarce and strictly endemic species. Iran's population genetic structure, genetic variation, and morphological variations are all unknown. Because of the therapeutic value of this species, six regional populations of Aegilops tauschii were studied for genetic diversity and population structure. To uncover within and among population genetic variation in this plant, we employed six inter-retrotransposon amplified polymorphism (IRAP) markers and 15 combined IRAP markers. The AMOVA test indicated a substantial genetic difference (PhiPT = 0.66, P = 0.010) among the tested populations, as well as the fact that 85 percent of overall genetic differences was related to within-population variety and 15 percent to genetic divergence across populations. The Mantel test revealed a substantial positive connection between genetic distance and geographical distance across the populations investigated. Based on (IRAP) markers, these findings suggested that regional populations of Aegilops tauschii are well separated.
