“…The Mantel test between morphological and molecular data yielded a quite low correlation value, similarly to other studies (Fanizza et al 1999;Allel et al 2017;Giordani et al 2017;Burgos et al 2018). Several factors might justify the somewhat unexpected low correlation.…”

Corema album (L.) D. Don is the only species of the genus Corema growing naturally on sand dunes throughout the Atlantic coast of the Iberian Peninsula, noted for the white coloured berries and nutritional value. The lack of information on genetic studies of the species is one of the most limitations for the establishment of this species as a new culture. Thus, this study focuses on the assessment of the genetic diversity based on inter-simple sequence repeats (ISSR) molecular markers and morphological traits. Seventy-one female plants, from four different sampled sites, were evaluated using six ISSR loci and eight morphological traits. Fifty polymorphic loci were detected. The dendrogram based on the UPGMA method and the principal coordinate analysis classified the 71 C. album genotypes into distinct clusters. The analyses revealed that accessions from the same geographical area were generally, but not entirely, clustered into the same group. Analysis of molecular variance was higher among populations, than within populations. The analysis of morphological traits revealed that there is no distinct separation among the C. album genotypes grown in different geographic areas. To our knowledge, this is the first study on the assessment of the genetic diversity in this species.

Alien disomic addition lines are valuable genetic resources for breeding programs under wide hybridization. The present study was carried out to identify the chromosome location of ISSR markers and genes controlling seed germination under drought stress in wheat-barley disomic addition lines. Germination experiment was performed at 0, -4 bar and -8 bar levels in a completely randomized design with three replications. The Germination Index, Germination Percentage, Coefficient of Germination Velocity, Mean Germination Time, Mean Germination Daily, and Plantlet Growth Speed were measured. Based on karyotype analysis, the presence of addition chromosomes was confirmed. The IS 10 (0.494) and IS 15 (0.395) primers showed the greatest polymorphism among the addition lines. The primers amplified most parts of the chromosomes 2H, 3H, and 7H, indicating these ISSR primers are located on these chromosomes. It is also indicated that most of the genes responsible for the seed germination under drought stress are located on chromosomes 4H and 5H.

“…Given that crop landraces are generally well adapted to the agroclimatic conditions of the region where they evolved and may contain a large genetic variation [ 24 ], they represent an interesting source for the selection of drought-tolerant materials. Barley landraces from Tunisia are genetically variable [ 18 , 25 ] and therefore are amenable to selection for drought tolerance, as long as diversity exists for this trait. In this respect, Ben Khaled et al [ 18 , 26 ] found genetic variation for salinity tolerance among different landrace accessions of the “Ardhaoui” barley, which is autochthonous of southern Tunisia and is grown in areas with low precipitation.…”

Variable Levels of Tolerance to Water Stress (Drought) and Associated Biochemical Markers in Tunisian Barley Landraces

Due to its high tolerance to abiotic stress, barley (Hordeum vulgare) is cultivated in many arid areas of the world. In the present study, we evaluate the tolerance to water stress (drought) in nine accessions of “Ardhaoui” barley landraces from different regions of Tunisia. The genetic diversity of the accessions is evaluated with six SSR markers. Seedlings from the nine accessions are subjected to water stress by completely stopping irrigation for three weeks. A high genetic diversity is detected among the nine accessions, with no relationships between genetic distance and geographical or ecogeographical zone. The analysis of growth parameters and biochemical markers in the water stress-treated plants in comparison to their respective controls indicated great variability among the studied accessions. Accession 2, from El May Island, displayed high tolerance to drought. Increased amounts of proline in water-stressed plants could not be correlated with a better response to drought, as the most tolerant accessions contained lower levels of this osmolyte. A good correlation was established between the reduction of growth and degradation of chlorophylls and increased levels of malondialdehyde and total phenolics. These biochemical markers may be useful for identifying drought tolerant materials in barley.
