KAMENOVA, I., 2016. Non-transmission of plum pox virus through seeds of myrobalan and apricot. Bulg. J. Agric. Sci., 22: 267–271 Seeds from wild-grown myrobalan (Prunus cerasifera Ehrh.) infected with PPV-D strain and from apricot (P. armeniaca) infected with PPV-Rec strain were investigated for their potential role in virus transmission. The presence of PPV was checked in fully ripe seeds, gem...

Apricot (Prunus armeniaca) belonging to the Prunus species is a popular kind of stone fruit tree. Apricot is native to Armenia and is currently cultivated in many countries with climates adaptable for apricot growth. In general, fresh fruits as well as dried apricot are produced. However, the information associated with genes and genetic markers for apricot is very limited. In this study, we ca...

An in vitro zygotic embryo germination protocol was developed for apricot (Prunus armeniaca L. “Hacıhaliloğlu”). A hundred percent of germination was obtained when isolated embryos were cultured in vitro, a result alike those reported in the literature with traditional dormancy breaking treatments. In vitro seedling development was optimal in a modified full-strength Murashige and Skoog (1962) ...

Male sterility is defined as the deviant condition in normally bisexual plants when no viable pollen is formed (Frankel and Galun, 1977). Male sterility has been exploited as an effective tool to aid hybrid seed production in many crops. Using this trait, seed producers can transform one inbred from a planned hybridization into a “female” line, thereby ensuring seed of hybrid origin on the male...

Research to date indicates that post-transcriptional gene silencing (PTGS) is an effective strategy for the development of stable high-level resistance to Plum pox virus in plum. Field tests in Poland, Romania, and Spain show that after 5–6 years of natural aphid vectored inoculation, trees of the PTGS clone C5 remain virus-free. The effectiveness of transgene-based PTGS for imparting potyvirus...

Pseudomonas syringae pv. persicae is a pathogen that causes bacterial decline of stone fruit. Here, we report the draft genome sequence for P. syringae pv. persicae, which was isolated from Prunus persica.

Sweet cherry (Prunus avium L.) is one of the most important stone fruit species in Bulgaria. The known to be susceptible more than 30 viruses. Among them are prune dwarf virus (PDV), prunus necrotic ringspot (PNRSV) and apple mosaic (ApMV), ilarviruses. Testing for these viruses required certification schemes order provide virus-tested propagated material fruit-growing industry prevent their di...

Self-incompatibility enables flowering plants to discriminate between self- and non-selfpollen. In Prunus, the 2 genes determining specificity are the S-RNase (the female determinant that is a glycoprotein with ribonuclease activity) and the SFB (the male determinant, a protein with an F-box motif). In all Prunus S haplotypes characterized so far, with the exception of Prunus armeniaca S(2) hap...

The present study describes possible changes in plasma levels of anterior pituitary hormones induced by bitter apricot (Prunus armeniaca L.) seeds in young female rabbits in vivo. Prunus armeniaca L. is an important medicinal edible plant species commonly known as “apricot”. The apricot is a member of the Rosaceae and subfamily Prunoideae. It is one of the most delicious and commercially traded...
