Opis:
Both Globodera rostochiensis (Wollenweber, 1923) Behrens, 1975 and Globodera pallida (Stone, 1973) are considered the most economically important nematode pest. Annual regional survey conduct in Poland have revealed high infestation of pathotype Ro1 to the northwest of the country and presence of new pathotype Ro5 of G. rostochiensis. In 2009-2013 fifty eight soil samples were tested. parasitic root organisms cause significant losses in quantity and quality of potato crops. In many European countries PCN have become a major problem in potato production mainly in starch potato cultivars. The pathotype Ro1 was detected mostly in central and northern Poland and pathotype Ro5 in four separated provinces: malopolskie, lubuskie, lubelskie and pomorskie. The abundance of cysts in location where the new pathotype was detected suggests that is a thread of further spread of pathotype Ro5 of G. rostochiensis in the country. Consequently, producers and farmers need to grow resistant potato cultivars to keep nematode population below damaging level. These results indicate the urgent need to prevent the spread of PCN to non-infested areas. This report focused on identification of nematode pathotypes in soil samples from infested polish fields and presentation of G. rostochiensis distribution on territory of Poland.

Opis:
The cyst nematodes belonging to the genus Globodera are big worldwide problem in countries were Sola-naceaous plants growing. Knowledge of species-composition in populations of Globodera rostochiensis and Globodera pallida is very important for selection of appropriate measure of nematode regulations occurrence. Inter- and intraspecific variability among species of Globodera rostochiensis and Globodera pallida were studied intensively with the use of molecular analyses of DNA methods. This review summarize and compare of methods chosen to distinguishing between Globodera, both pathotypes and species.

Opis:
Globodera rostochiensis, as well as other cyst nematodes, induces formation of a multinucleate feeding site, called syncytium, in host roots. In tomato roots infected with a potato cyst nematode, the syncytium is initiated in the cortex or pericycle. Progressive cell wall dissolution and subsequent fusion of protoplasts of newly incorporated cells lead to syncytium formation. Expansion and development of a syncytium strongly depends on modifications of a cell wall, including its degradation, elongation, thickening, and formation of ingrowths within it in close contact with tracheary elements. Recent reports have demonstrated that during formation of syncytium, numerous genes of plant origin, coding for cell wall-modifying enzymes are up-re-gulated. In this research, we studied a detailed distribution and function of two tomato 1,4-β-endoglucanases in developing feeding sites induced by G. rostochiensis. In situ localization of tomato LeCel7 and LeCel8 transcripts and proteins demonstrated that these enzymes were specifically up-regulated within syncytium and in the cells adjacent to the syncytium. In non-infected roots an expression of LeCel7 and LeCel8 was observed in the root cap and lateral root primordia. Our data confirm that cell wall-modifying enzymes of plant origin have a role in a modification of cell wall within syncytia, and demonstrate that plant endoglucanases are involved in syncytia formation.

Opis:
The sequence of anatomical and ultrastructural events leading to the syncytium development in tomato roots infected with Globodera rostochiensis was examined. The syncytia were preferentially induced in cortical or pericyclic cells in the elongation zone of root. They developed towards the vascular cylinder by incorporation of new cells via local cell wall breakdown. After surrounding primary phloem bundle and reaching xylem tracheary elements syncytia spread along vascular cylinder. Roots in primary state of growth seemed to be the best place for syncytium induction as syncytia formed in the zone of secondary growth were less hypertrophied. At the ultrastructural level syncytial elements were characterized by strong hypertrophy, breakdown of central vacuole, increased volume of cytoplasm, proliferation of organelles, and enlargement of nuclei. On the syncytial wall adjoining vessels the cell wall ingrowths were formed, while the syncytial walls at interface of phloem were considerably thickened. They lacked of functional plasmodesmata and did not form any ingrowths. Using immunofluorescent-labelling and immunogold-labelling methods tomato expansin 5 protein was localized in nematode infected roots. The distribution of LeEXP A5 was restricted only to the walls of syncytia. The protein distribution pattern indicated that LeEXP A5 could mediates cell wall expansion during hypertrophy of syncytial elements.
