Similarities and differences in molecular pattern of ITS region of some Globodera rostochiensis populations

Abstract

Evolutionary relationships of organisms in the past are based on morphological, biogeographical, and paleontological data. The emergence of molecular tools has enabled the study of the genetic structure of organisms and study of their phylogeny using protein or nucleotide sequences, which is especially important for organisms such as cyst nematodes that have no fossil records and are morphologically very similar. This paper presents molecular characterization of some G. rostochiensis populations in our region based on molecular pattern of ITS region. Molecular characterization of the studied populations showed similarities with the previously characterized populations but also some differences.

Evolutivni odnosi organizama u prošlosti su zasnivani na morfološkim, biogeografskim i paleontološkim podacima. Pojava molekularnih alata omogućila je izučavanje genetičke strukture organizama i proučavanje njihove filogenije uz pomoć proteinskih ili nukleotidnih sekvenci, što je posebno značajno kod organizama kao što su cistolike nematode koje nemaju fosilnih ostataka a morfološki su veoma slične. U ovom radu je data molekularna karakterizacija nekih populacija G.rostochiensis sa naših prostora u molekularnom paternu ITS regiona. Molekularna karakterizacija ispitivanih populacija je pokazala sličnosti ispitivanih populacija sa već ranije okarakterisanim populacijama ali i neke razlike.
