Morphometric analysis and genetic diversity in Glaucium (Papaveraceae) using sequence related amplified polymorphism
Keywords:population structure, gene flow, network, genetic admixture
Glaucium belongs to the Papaveraceae family. Glaucium is a genus of annual, biennial, and perennial herbaceous plants that thrive on salty soils and near the sea.Glaucium is represented by a total of 10 taxa in Iran. Sequence-related amplified polymorphism was used to estimate genetic diversity. A combination of morphological and genomic data was used to identify genetic diversity and species features in Glaucium species. In eight provinces, 65 people connected to five Glaucium were gathered. Through polymerase chain reaction (PCR) amplification of five Glaucium species, a total of 144 (Number of total loci) (NTL) DNA bands were obtained. These bands were created by combining 10 different selective primers. The total number of amplified fragments varied from seven to twenty-six. The expected unbiased heterozygozity (H) ranged from 0.19 (G. grandiflorum subsp. grandiflorum var. grandiflorum) to 0.33 (G. grandiflorum subsp. grandiflorum var. grandiflorum) (G. oxylobum var. oxylobum). The genetic similarities between five species range from 0.63 to 0.88. The findings of clustering revealed two large groupings. The SRAP (Sequence-related amplified polymorphism) markers study revealed that G. grandiflorum and G. oxylobum var. oxylobum had the least similarity. This investigation also discovered a substantial indication of distance isolation (Mantel test results). The current findings indicate that sequence-related amplified polymorphism can discover and understand genetic affinity in Glaucium species. The current findings have consequences for biodiversity and conservation efforts. Aside from that, the current findings may pave the way for identifying acceptable ecotypes for grazing and pasture uses in Iran.
