Description
Summary:Characterization of genetic diversity is a must for exploring the genetic resources for plant development and improvement. Prosopis cineraria is ecologically imperative species known for its innumerable biological benefits. Since there is a lack of genetic resources for the species, so it is crucial to unravel the population dynamics which will be very effective in plant improvement and conservation strategies. Of the 41 genomic microsatellite markers designed from (AG)n enriched library, 24 were subsequently employed for characterization on 30 genotypes of Indian arid region. A total of 93 alleles with an average 3.875 could be amplified by tested primer pairs. The average observed and expected heterozygosity was 0.5139 and 0.5786, respectively with 23 primer pairs showing significant deviations from Hardy-Weinberg equilibrium. Polymorphic information content average to 0.5102 and the overall polymorphism level was found to be 93.27%. STRUCTURE analysis and DARwin exhibited the presence of 4 clusters among 30 genotypes.
