Abstract |
Background: The genus Limonium is morphologically highly diverse, which
complicates its taxonomy. The diversity of the genus has been assigned to the
increased capacity of hybridization, in combination with the ability of the hybrids to
produce asexually viable seeds and remain in populations.
Targets: Here, the study of the genetic diversity of Limonium taxa in SE Crete is
attempted, in order to reveal whether the morphometrics converge with the genetic
characteristics and the role of the epigenetic factor.
Methodology: Sampling took place in 11 sites of the SE Crete and in total 60
specimens have been collected, including six taxa, four of which were endemics.
Morphometric analysis completed for all the specimens, while 44 specimens have
been used for DNA extraction. Genetic diversity was analyzed using Amplified
Fragment Length Polymorphisms (AFLPs), while epigenetic modifications were
analyzed using Methyl-Sensitive Amplification Polymorphisms (MSAP).
Results: The results revealed whether the morphometrics converge with genetic
characteristics in the characterization of Limonium taxa in the area and the role of
epigenetic factor.
Conclusions: Although high morphological variability is presented between endemic
taxa, at the genetic diversity level the high genetic variability is presented among nonendemic
and endemic taxa or in specific cases between non-endemic taxa. Epigenetics
follow similar pattern in variation with morphological characteristics, with nonendemic
taxa as the only exception.
