چکیده

The Argania is an endemic genetic resource in Morocco holding an important ecological and socio-economical benefit. However, overgrazing and overharvesting lead to a serious downturn in the number of trees. To characterize genetic diversity within and among 24 populations, represented by 240 argan trees, four combinations of SRAP primers and eight combinations of REMAP primers were used. A total of 338 REMAP and 146 SRAP markers were amplified with a polymorphism of 100%. The average polymorphism information content value was 0.20 and 0.17 for SRAP and REMAP markers, respectively. The analysis of molecular variance showed that 26% of the genetic variation was partitioned among populations. The coefficient of gene differentiation was 0.2875 and gene flow was 1.2391. The average parameter diversity was: observed number of alleles (Na)=0.729, effective number of alleles (Ne)=1.131, Shannon’s information index (I)=1.143; Nei’s gene diversity (H)=0.093 and Percentage of Polymorphic Loci=35.68. The STRUCTURE and principal coordinate analysis revealed that the Argania spinosa L. populations were aggregated into 2 genetic groups. To detect outlier, baysecan software was used and 21 were detected (7 under selection, 14 under balancing selection) presenting posterior probability higher than 0.79. The current results can be explored in the design of management programs and to comprehend the adaptation mechanism of Argan tree.

This study describes the genetic relationships among 34 varieties of Lallemantia iberica using inter-retrotransposon amplified polymorphism (IRAP) and retrotransposon-microsatellite amplified polymorphism (REMAP). Samples were collected from Agriculture Research Center of Urmia city (northwest Iran). Ten IRAP and REMAP primers generated 76 scorable electrophoretic bands with 78.94% pol...

Spinach (Spinacia oleracea L.) is an economically important leafy vegetable crop in many countries. This is the first case study of using SRAP markers to analyze genetic diversity of Iranian spinach accessions. Eight SRAP primer combinations generated 88 scorable bands ranging from 50 to 1000 bp, among which 73 were polymorphic, with an average of 82.9 polymorphic bands per primer combination a...

In this study, genetic diversity was evaluated for 40 landraces and improved rice genotypes by inter-simple sequence repeat (ISSR), IRAP (Inter-Retrotransposon Amplified) and REM (Retro transposon-Microsatellite AmplifiedPolymorphism) marker systems. Amplified productions of 20 primers indicated distinct and polymorphic bands among genotypes that produced a total of 309 bands and an average of ...

the effectiveness of irap, remap, ssr, and issr markers were investigated to assess genetic diversity among and within eight medicago sativa l. populations. a total of 101, 119, 117 loci and 31 alleles were amplified using 10 irap, 14 remap, 16 issr and eight ssr primers, respectively. irap markers generated the maximum proportion of polymorphic loci per primer (pplp) while the maximum value of...

Pistachio is one of the most important horticultural products of Iran. The best way to get the maximum yield is to have genetically pure and monotonous gardens. Thereby, study of genetic variation and providing genetic identifications, make this possible to have homogenous gardens with high performance genotypes. In the present study, genetic diversity of 19 Iranian pistachio cultivars was asse...

TrnL-F region including intron trnL (UAA) and trnL (UAA) - trn (GAA) spacer in the large single-copy region of the chloroplast genome is widely used to infer phylogenetic relationships in plants. In this study, we obtained the trnL-F sequences from 8 samples of Arum L. in Iran. Phylogenetic analyses were conducted by the Bayesian inference, maximum parsimony, and maximum likelihood methods. The...
