Sharka, caused by the plum pox virus (PPV), a potyvirus transmitted by aphids, is the most severe viral disease affecting stone fruits, including apricot (Prunus armeniaca L.), and poses a critical threat to cultivation, especially in Europe where the disease has become endemic. PPV is a nonregulated pathogen with little effective agronomic controls; thus, the primary strategy for managing the disease relies on preventive measures to ensure that plant material remains free of the virus. To this end, the introduction of novel resistance genes to PPV is crucial as genetic resistance remains the most effective and economical strategy for long-term disease management. In addition, the disclosure of resistance genes in apricot is a prerequisite to study similar resistance genes in other stone fruits.

Abstract
Sharka, caused by the plum pox virus (PPV), a potyvirus transmitted by aphids, is the most severe viral disease affecting stone fruits, including apricot (Prunus armeniaca L.), and poses a critical threat to cultivation, especially in Europe where the disease has become endemic. PPV is a nonregulated pathogen with little effective agronomic controls; thus, the primary strategy for managing the disease relies on preventive measures to ensure that plant material remains free of the virus. To this end, the introduction of novel resistance genes to PPV is crucial as genetic resistance remains the most effective and economical strategy for long-term disease management. In addition, the disclosure of resistance genes in apricot is a prerequisite to study similar resistance genes in other stone fruits.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
