SEOPA-1 and GOLGI-2 Apricot Seedlings Are Resistant to Plum Pox Virus

Apricot (Prunus armeniaca L.) production was 2.8 million tons in 2001 (FAO, 2001), making it the third most important stone fruit species worldwide. However, the spread of Plum Pox Virus (PPV), also known as sharka, is the most important limiting factor to the apricot industry in Europe. During the...

Description
Summary:Apricot (Prunus armeniaca L.) production was 2.8 million tons in 2001 (FAO, 2001), making it the third most important stone fruit species worldwide. However, the spread of Plum Pox Virus (PPV), also known as sharka, is the most important limiting factor to the apricot industry in Europe. During the 1980s and 1990s, apricot production was seriously affected by PPV in Spain, France, and Italy (Roy and Smith, 1994). Apricot is very sensitive to all strains of PPV, resulting in serious damage to the fruits (deformation, necrotic spots on pits and flesh, and dry flesh). PPV is spread by aphids in a nonpersistent way: acquisition time by the aphids lasts seconds, retention lasts minutes and the virus is transmitted via the stylet (Nault, 1997). This fact makes chemical control of the aphid vector inefficient. Removal of infected trees was ineffective in eradicating the disease in Spain (Llácer and Cambra, 1998). The only reliable control of the PPV is to use resistant cultivars. However, there are no resistant cultivars adapted to the mild winters in southern Europe.
