Expansins are a group of plant cell wall loosening proteins. In animals, functional expansin (EXPB1) has been discovered in the golden potato cyst nematode Globodera rostochiensis. In plant-parasitic nematodes expansins act as the parasitism factors or effectors. Molecularvariability of another expansin (expB2) gene was eva- luated in the diverse populations of the G. rostochiensis. Comparison of the expB2 genestructure in the two potato cyst nematode species, G. rostochiensis and G. pallida, revealed lack of all four introns in expB2 gene of G. pallida species. Possible loss of introns in Gp-expB2 is discussed.
