Morphological and Molecular Diversity Among Heliotropium greuteri Samples

28365

The aims of this study were to characterize Heliotropium greuteri H. RIEDL plants for some selected morphological characters, and to investigate their diversity and relationships by using inter-simple sequence repeat (ISSR) markers. Forty-seven H. greuteri and one H. lasiocarpum genotypes as control were used in this study. The plant materials were collected from the sites of Erciyes University and city of Develi, Kayseri, Turkey, and characterized for plant structure, flower structure, seed characteristics and molecular marker diversity. Plant heights ranged from 13 to 110 cm, averaging 28 cm. Flower diameters ranged from 1.35 to 18.5 mm, averaging 9.78 mm. All traits studied indicated variations, which were indicated potential for improvement as ornamental plant. For ISSR analysis, 13 ISSR primers selected based on initial screening with 20 primers were applied to all samples, which produced 90 polymorphic markers. Dice’s genetic similarity values varied between 0.81 and 0.99, which was relatively narrow. Probably this species faced a recent bottleneck or speciation has arisen recently resulting in narrowed diversity. Overall, H. greuteri plants indicated potential for ornamental use due to their relatively drought tolerance, fragrance, extended flowering time and honeybee attraction.
