In vitro micropropagation of wild cherry is presently one of the main commercial ways to clonally propagate this species (Cornu and Boulay, 1986). In order to extend this technique to a large number of clones, it seems necessary to improve our knowledge of the behavior of the explants during the in vitro culture. Since plant growth regulators (PGR) play an important role in this technique (Marg...

The activity of Prunus dulcis (sweet almond) β-glucosidase at the expense of p-nitrophenyl-β-d-glucopyranoside at pH 6 was determined, both under steady-state and pre-steady-state conditions. Using crude enzyme preparations, competitive inhibition by 1-5 mM imidazole was observed under both kinetic conditions tested. However, when imidazole was added to reaction mixtures at 0.125-0.250 mM, we d...

Mapping and sequencing of the non-dormant evg mutant in peach [Prunus persica (L.) Batsch] identified six tandem-arrayed DAM (dormancy-associated MADS-box) genes as candidates for regulating growth cessation and terminal bud formation. To narrow the list of candidate genes, an attempt was made to associate bud phenology with the seasonal and environmental patterns of expression of the candidate...

UNLABELLED • PREMISE OF THE STUDY Microsatellite primers were developed in the beach plum, Prunus maritima, to investigate the genetic composition of remaining populations in need of conservation and, in future studies, to determine its relation to P. maritima var. gravesii. • METHODS AND RESULTS Fourteen primer pairs were identified and tested in four populations throughout the species' ge...

The distribution of Ilarvirus species populations amongst 61 Australian Prunus trees was determined by next generation sequencing (NGS) of amplicons generated using a genus-based generic RT-PCR targeting a conserved region of the Ilarvirus RNA2 component that encodes the RNA dependent RNA polymerase (RdRp) gene. Presence of Ilarvirus sequences in each positive sample was further validated by Sa...

Despite the agronomical importance and high synteny with other Prunus species, breeding improvements for cherry have been slow compared to other temperate fruits, such as apple or peach. However, the recent release of the peach genome v1.0 by the International Peach Genome Initiative and the sequencing of cherry accessions to identify Single Nucleotide Polymorphisms (SNPs) provide an excellent ...

prunus divaricata ( alloocheh ) is a small tree cultivating in iran, middle east and central asia. prunus genus has many species with anti-oxidant, anti-hyperlipidemia and anti-hyperglycemia effects. in the present study the anti-diabetic and anti-hyperlipidemic effects of p. divaricata fruits were examined in normal and streptozotocin (stz)-induced diabetic rats. both groups, control and refer...

BACKGROUND Traditional alcoholic beverages (TABs) have only received marginal attention from researchers and ethnobotanists so far, especially in Italy. This work is focused on plant-based TABs in the Alta Valle del Reno, a mountainous area on the border between Tuscany and Emilia-Romagna regions. The aims of our study were to document local knowledge about TABs and to analyze and discuss the d...

Tetraploid sour cherry (Prunus cerasus L.) exhibits gametophytic self-incompatibility (GSI) whereby the specificity of self-pollen rejection is controlled by alleles of the stylar and pollen specificity genes, S-RNase and SFB (S haplotype-specific F-box protein gene), respectively. As sour cherry selections can be either self-compatible (SC) or self-incompatible (SI), polyploidy per se does not...

In this study the sensitivity of peach tree (Prunus persica L.) to three water stress levels from mid-pit hardening until harvest was assessed. Seasonal patterns of shoot and fruit growth, gas exchange (leaf photosynthesis, stomatal conductance and transpiration) as well as carbon (C) storage/mobilization were evaluated in relation to plant water status. A simple C balance model was also develo...
