One factor that contributes to a successful fruit tree grafting is the establishment of symplasmic contacts in the graft interface to facilitate the transfer of compounds between scion and stock. Using novel experimental and theoretical approaches we investigated whether the localized incompatibility, experienced in some Prunus grafts, could be related to insufficient plasmodesmal coupling at a...

Plum pox virus (PPV) causes the most economically-devastating viral disease in Prunus species. Unfortunately, few natural resistance genes are available for the control of PPV. Recessive resistance to some potyviruses is associated with mutations of eukaryotic translation initiation factor 4E (eIF4E) or its isoform eIF(iso)4E. In this study, we used an RNA silencing approach to manipulate the e...

Flower color is an important trait of the ornamental peach (Prunus persica L.). However, the mechanism responsible for the different colors that appear in the same genotype remains unclear. In this study, red samples showed higher anthocyanins content (0.122 ± 0.009 mg/g), which was significantly different from that in white samples (0.066 ± 0.010 mg/g). Similarly to carotenoids content, red ex...

Promising new tools for peach fruit quality breeding have been revised in this work. These tools included fruit quality evaluation through physical, chemical and sensorial parameters and post-harvest storage evaluation. The development of a feasible method for an early testing of peach selections generated in breeding programs is also well described together with the discussion of the inheritan...

In this study the abundance and location of phosphoenolpyruvate carboxykinase (PEPCK) was determined in the flesh and skin of the sweet cherry (Prunus avium L.) cultivar Durone Nero II during development. PEPCK was not present in young fruit but appeared in both tissues as the fruit increased in size. In these there was no net dissimilation of malic acid, which accounts for the bulk of their or...

The acyclic polyol sorbitol is a primary photosynthetic product and the principal photosynthetic transport substance in many economically important members of the family Rosaceace (e.g. almond [Prunus dulcis (P. Mill.) D.A. Webber], apple [Malus pumila P. Mill.], cherry [Prunus spp.], peach [Prunus persica L. Batsch], and pear [Pyrus communis]). To understand key steps in long-distance transpor...

Article info: Received: 9 April 2014 Accepted: 6 August 2014 ABSTRACT An effective in vitro culture system for mature nodal segments of European plum (Prunus domestica) was established. Several important aspects of regeneration from nodal explants were studied for adaptation of European plum in Bangladesh. Leaf explants were used for callus induction and 1⁄2 MS media supplemented with 1.0 mg/l ...

Cherry laurel (Prunus laurocerasus L.) has attracted attention because of many different usage such as fresh fruit production, processing material for medicinal and pharmacy industry. This study carried out some pomological, chemical and phenological properties of cherry laurel phenotypes to selection of the favorable phenotypes for cultivation. A total of 40 phenotypes were evaluated in the pr...
