Results of research aiming at monitoring of climate changes impact on plant pathogens distribution such as <i>Zucchini yellow mosaic virus</i> (ZYMV), quarantine <i>Plum pox virus</i> (PPV) and quarantine phytoplasma European stone fruit yellows (ESFY) are presented here. ZYMV has spread from Northern Italy across Austria up to Central Moravia and Bohemia. PPV has been continuously spreading from the lowlands of Central Bohemia and Moravia up to plains. Later, from the sixties and seventies of the last century, due to climate warming and human activities the virus quickly spread to uplands, foothills and mountains of the Czech Republic. Phytoplasma ESFY was spreading in a manner similar to ZYMV in the eighties of the twentieth century from Northern Italy and currently is affecting mainly apricot and peach trees in Southern Moravia.

The distribution of <i>Plum pox virus</i> (PPV), <i>Prune dwarf virus</i> (PDV), <i>Prunus necrotic ringspot virus</i> (PNRSV), <i>Apple chlorotic ringspot virus</i> (ACLSV) and <i>Apple mosaic virus</i> (ApMV) in naturally growing shrubs of blackthorn and road-bordering trees of plum and myrobalan, and of PPV, PDV, PNRSV and <i>Cherry leafroll virus</i> (CLRV) in sweet and sour cherry trees were investigated. The most widely distributed viruses were PPV in plums (74% of the investigated trees were infected); PPV, PDV, and PNRSV in myrobalans (26%, 11% and 18%, respectively), PDV in blackthorns (27%), and PDV and PNRSV in cherries (25% and 22%). PPV was not detected in sweet and sour cherries. The incidence of ACLSV and ApMV was negligible in individually growing trees of the genus Prunus in the Czech Republic.

The presence and distribution of PPV-M strain of Plum pox virus were investigated in selected orchards of apricots and peaches in the Czech Republic. PPV-M was found to be distributed in apricot and peach orchards planted with nursery material imported from abroad. The presence of PPV-M was not proved in orchards planted with trees from local nurseries. The absence of PPV-M in a majority of spontaneous PPV hosts was proved previously. PPV-M strain appears to have been introduced recently. &nbsp;

The presence and distribution of M strain of Plum pox virus (PPV-M) were investigated in natural hosts of&nbsp;Sharka, plums, myrobalans and blackthorns in the Czech Republic. Leaves or flowers of trees were evaluated for the presence of PPV by specific polyclonal antibodies at first. PPV infected samples were investigated for the presence of PPV-M by strain specific monoclonal antibodies. 102 PPV isolates from plum, 81 from myrobalan and 25 from blackthorn were typed. PPV-M was detected in six plum trees, six myrobalan trees and in one shrub of blackthorn. Sporadic incidence of PPV-M was proved in all investigated areas of the Czech Republic. Molecular and serological typing of different PPV strains in natural hosts, plum, apricot, and peach orchards was proposed to realize in Central Europe. &nbsp;
