The plants of Prunus mostly bloom in early spring, and the flowers various species possess their individual floral scent characteristics; mume, especially, can volatilize a large amount benzenoid compounds into air during flowering phase. In order to elucidate molecular basis differences volatile capacity aromatic substances among flowers, endogenous headspace components expression ABCG genes w...

Flowering control is one of the several strategies for gene containment of transgenic plants. TERMINAL FLOWER 1 (TFL1) is known to be involved in the transcriptional repression of genes for inflorescence development. Two TFL1 transcripts with different 3' UTR were cloned from black cherry (Prunus serotina Ehrh.) using reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplificat...

Prunus (Rosaceae) includes many commercially important fruit crop species that exhibit self-incompatibility (SI), including sweet cherry (P. avium L.), Japanese apricot mume Sieb. et Zucc.), plum salicina Lindl.), armeniaca and almond dulcis [Mill.] D. A. Webb.). These S-ribonuclease-based gametophytic SI, which prevents self-pollen tube growth in the pistil. The successful production of self-f...

Transgenic trees currently are being produced by Agrobacterium-mediated transformation and biolistics. Since trees are particularly suited for long-term evaluations of the impact of the technology, Prunus subhirtella autumno rosa (PAR) was chosen as model fruit tree species and transformed with a reporter gene (uidA) under the control of the 35S promoter. Using Southern and GUS fluorometric tec...

ABSTRACT Thirteen aphid species were tested for their ability to transmit Pennsylvania isolates of Plum pox virus (PPV) collected in Columbia (PENN-3), Franklin (PENN-4), and York (PENN-7) Counties, PA. Four species, Aphis fabae, A. spiraecola, Brachycaudus persicae, and Myzus persicae, consistently transmitted PPV in preliminary transmission tests. Two species, Metopolophium dirhodum and Rhopa...

A severe outbreak of European Stone Fruit Yellows (ESFY) has been reported recently in apricot (Prunus armeniaca) orchards located in the province of Trento (Italy), where partial or total tree dieback caused major economic losses to growers. In order to prevent the disease spreading, the presence of ESFYP-vector, the psyllid Cacopsylla pruni, was monitored together with wild reservoirs of the ...

apricot (prunus armeniaca), palys an important role in fruit production industry in iran. irregular set of fruit, caused by either sterility of flower organs or incompatibility has been the main problem in apricot production over the years. in this study, it has been attempted to determine these phenomena for four apricot cvs. namely ‘shahroodi’, ‘nasiri’, ‘jahangiri’ and ‘noori’ through the me...

In the present study, chemical composition and in situ rumen dry matter degradability (DMD) of some tree species (cherry, apricot and almond tree leaves) were determined. Crude protein (CP) concentration varied from 6.76% for almond tree to 2.76% for cherry tree, neutral detergent fiber (NDF) and acid detergent fiber (ADF), from 29.2, 20.8% for apricot tree to 20.8 and 15.8% for almond tree lea...

this study was conducted with the main purpose of investigating genetic variation among 13 selected sweetcherry (prunus avium cv. siah mashhad) genotypes, i.e., the most important iranian sweet cherry cultivars based on their pomological, morphological, and phonological characteristics. the experiment was laid out in a randomized complete block design with three replications at khorasan-e-razav...
