Najas genties augalų genetinės įvairovės tyrimas taikant SCoT žymenis /

Najas marina and Najas major are important components of ecosystems, but their morphological features are often overlapping and variable, making identification of these species difficult. The identification of these species is important because they are used as bioindicators for the quality of water bodies according to the European Water Framework Directive, but they indicate different ecological states of the bodies. For this reason, the genetic diversity of 6 Lithuanian populations of N. marina and N. major was investigated using SCoT (Start codon targeted) markers and compared with ISSR (Inter simple sequence repeats) marker data of another PhD student. The results of principal coordinate analysis (PCoA), analysis of molecular variation (AMOVA) along with Shannon index, expected heterozygosity and unique loci values showed that ISSR is particularly useful in distinguishing between these species, but shows low intraspecific variation. SCoT poorly separated both species but revealed higher intraspecific diversity. Due to the nuances of both markers influencing genetic diversity in their genomic targets, further studies with additional markers are desirable to gain a better understanding of the intraspecies structure of N. marina and N. major populations.
