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...

This study aimed to identify fungal species associated with trunk diseases of sweet cherries (Prunus avium) in several commercial cherry orchards Beijing, Guizhou and Shandong provinces, China. In total, eighteen strains that fitted well into the concept Diaporthe were isolated. Based on both morphological multi-locus phylogenetic analyses internal transcribed spacer region (ITS), beta-tubulin ...

Prunus necrotic ringspot virus (PNRSV) causes yield loss in most cultivated stone fruits, including sweet cherry. Using a small RNA deep-sequencing approach combined with end-genome sequence cloning, we identified the complete genomes of all three PNRSV strands from PNRSV-infected sweet cherry trees and compared them with those of two previously reported isolates.

We conducted SSR analyses of 59 accessions, including 29 traditional plum (Prunus domestica), 24 sweet cherry (Prunus avium), and 1 sour cherry (Prunus cerasus) selected from East Anatolian gene sources and 3 plum and 2 cherry reference accessions for molecular characterization and investigation of genetic relationships. Eight SSR loci [1 developed from the apricot (UDAp-404), 4 from the peach ...

Endophytic fungi constitute a remarkable multifarious group of microorganisms live within plants tissues without causing any obvious negative effect. Endophytic fungi have been found in every plant species examined to date. During an investigation on endophytic fungi, 123 fungal isolates were obtained from healthy twigs and leaves of cherry (Prunus avium) and sour cherry (P. cerasus) trees in I...

To break dormancy and increase the germination of Prunus avium L. (mazzard cherry) seeds, various methods were tested including the removal of the seed coat after cold moist stratification and treatment with GA3, KNO3, or thiourea. Treatments with 7,500 ppm KNO3 after 120 days of stratification were more effective, yielding 64.54% germination of seeds with coat. In seeds without coat, 500 ppm G...

Representatives of the Prunus genera, found in almost every country and continent, have been recognized not only for their delicious fruits nuts, but also because beneficial properties. To date, numerous cultivars phytochemically studied, leading to identification various compounds including terpenes, tannins, flavonoids, phenolic acids, carotenoids, fatty so on. Pharmacological studies on spec...

It was investigated whether premature fruit abscission in Prunus avium L. was triggered by a reduction in polar auxin transport (PAT). The capacity of pedicels to transport tritiated IAA ([3H]-IAA) via the PAT pathway was measured at intervals throughout flower and fruit development. The extent of passive diffusion, assessed by concurrent applications of [14C]-benzoic acid ([14C]-BA), was negli...
