Transcriptome analysis of peach (Prunus persica L. Batsch) during the late stage of fruit ripening.
Abstract
Fruit ripening is a complex developmental process, the details of which remain largely unknown in fleshy fruits. In this paper, the fruit flesh of two peach varieties, "Zhongyou9" (a nectarine; Prunus persica L. Batsch) and its mutant "Hongyu", was analyzed by RNA-seq technology during two stages of ripening at 20-day intervals. One hundred and eighty significant upregulated and two hundred and thirty-five downregulated genes were identified in the experiment. Many of these genes were related to plant hormones, chlorophyll breakdown, accumulation of aroma and flavor volatiles, and stress. To the b...

Measures of Diet Quality across Calendar and Winter Holiday Seasons among Midlife Women: A 1-Year Longitudinal Study Using the Automated Self-Administered 24-Hour Recall
Conclusions In this population, diet quality is significantly lower during the winter holiday period, but mostly consistent by season. Multiple recalls in any season can give a reasonable representation of usual overall diet quality throughout the year. (Source: Journal of the Academy of Nutrition and Dietetics)

Yeasts isolated from figs (Ficus carica L.) as biocontrol agents of postharvest fruit diseases.
Abstract
Fresh fruit is highly perishable during postharvest life, mainly due to fungal growth. Thus, fungal control is an important goal for the fruit industry. In this work, a selection of antagonistic yeasts isolated from fig and breba crops were screened in vitro. The isolated yeasts were challenged with three moulds isolated from decayed figs and breba crops, identified as Penicillium expansum M639 and Cladosporium cladosporioides M310 and M624, and pathogenic moulds Botrytis cinerea CECT20518 and Monilia laxa CA1 from culture collections. Two yeast isolates, Hanseniaspora opuntiae L479 and Metschnik...

‘Candidatus Phytoplasma phoenicium’ associated with almond witches’-broom disease: from draft genome to genetic diversity among strain populations
Conclusion:
The genetic diversity within ‘Ca. P. phoenicium’ strain populations in Lebanon suggested that AlmWB disease could be associated with phytoplasma strains derived from the adaptation of an original strain to diverse hosts. Moreover, the identification of a putative inhibitor of apoptosis-promoting Bax factor (BI-1) in ‘Ca. P. phoenicium’ draft genome and within genomes of other ‘Ca. Phytoplasma’ species suggested its potential role as a phytoplasma fitness-increasing factor by modification of the host-defense response. (Source: BMC Microbiology)

Antifungal activity and mechanism of tea polyphenols against Rhizopus stolonifer.
CONCLUSION: The mechanism of action might be attributed to direct damage of the mycelium and spore and indirect induction of defensive enzyme activities. TP has the potential to be developed as an alternative to control post-harvest disease of fruit caused by R. stolonifer.

Notes from the field: listeriosis associated with stone fruit - United States, 2014.
Abstract
On July 19, 2014, a packing company in California (company A) voluntarily recalled certain lots of stone fruits, including whole peaches, nectarines, plums, and pluots, because of concern about contamination with Listeria monocytogenes based on internal company testing. On July 31, the recall was expanded to cover all fruit packed at their facility during June 1-July 17. After the initial recall, clinicians, state and local health departments, CDC, and the Food and Drug Administration (FDA) received many inquiries about listeriosis from concerned consumers, many of whom had received automated tele...

Modelling of 5-hydroxymethylfurfural photo-degradation by UV irradiation. Influence of temperature and pH
Publication date: Available online 8 March 2015 Source:Food Research International Author(s): Karla Aguilar , Alfonso Garvín , Ebner Azuara , Albert Ibarz The main aims of this study were (a) to prove that the UV irradiation of juices avoids the formation of 5-hidroxymethylfurfural (HMF), (b) to know the influence of temperature and pH on the UV photo-degradation of the HMF when it is unfortunately present in the juice (for example, after a previous thermal treatment or after a long storage period) and (c) to model this photo-degradation, proposing a reaction mechanism related to the power absorbed by the solution...

Are Nectarines to Blame? A Case Report and Literature Review of Spontaneous Bacterial Peritonitis Due to Listeria monocytogenes.
We present here a case of Listeria SBP in a 68-year-old man with previously unidentified cirrhosis. His infection occurred in the context of a nationwide fruit recall for Listeria contamination, prompting an epidemiologic investigation. After describing the case, we then review the extant literature on Listeria peritonitis. To date, no case studies on Listeria SBP have systematically described risk factors for Listeria acquisition. As incidence of Listeria SBP is increasing, however, knowledge of patient risk factors, especially foodborne exposure risks, may be important in preventing future episodes of Listeria SBP, and i...

A cixiid survey for natural potential vectors of ‘Candidatus Phytoplasma phoenicium’ in Lebanon and preliminary transmission trials
Abstract
Almond witches'‐broom (AlmWB) disease, associated with ‘Candidatus Phytoplasma phoenicium’, is an emerging threat with real risk of introduction in Euro‐Mediterranean Countries. Its rapid spread over large geographical areas suggests the presence of efficient insect vector(s). In the present work, a survey on cixiids was carried out in Lebanon in the years 2010–2013 in AlmWB‐infested almond and nectarine orchards. Insects were collected by means of different methods, identified with a stereo microscope, and analysed for phytoplasma identification through 16S rDNA PCR‐based amplification and nucleotid...

Asymmetrasca decedens (Cicadellidae, Typhlocybinae), a natural vector of ‘Candidatus Phytoplasma phoenicium’
Abstract
‘Candidatus Phytoplasma phoenicium’ is associated with a lethal disease of almond, peach and nectarine named almond witches'‐broom disease (AlmWB). The disease spread rapidly in Lebanon from coastal areas to elevations exceeding 1200 m, killing over 150,000 trees in a span of two decades. The mode of spread suggested the involvement of efficient vector(s) and Asymmetrasca decedens (Hemiptera, Cicadellidae) was suspected as it is the most abundant leafhopper species present in Lebanese stone fruit orchards. Living A. decedens specimens were collected from fields heavily infested by AlmWB and used in transmi...

Peach genetic resources: diversity, population structure and linkage disequilibrium
Conclusions:
Our study demonstrates a high level of genetic diversity and relatively fast decay of LD in the Oriental peach breeding program. Inclusion of Chinese landraces will have a greater effect on increasing genetic diversity in Occidental breeding programs. Fingerprinting with genotype data for all 658 cultivars will be used for accession management in different germplasms. A higher density of markers are needed for association mapping in Oriental germplasm due to the low extension of LD. Population structure and evaluation of LD provides valuable information for GWAS experiment design in peach. (Source: BMC Genetic...
