Na Cui, Peng-Cheng Yang, Kun Guo, Le Kang, Feng Cui
Host alternation, an obligatory seasonal shifting between host plants of distant genetic relationship, has had significant consequences for the diversification and success of the superfamily of aphids. However, the underlying molecular mechanism remains unclear. In this study, the molecular mechanism of host alternation was explored through a large-scale gene expression analysis of the mealy aphid Hyalopterus persikonus on winter and summer host plants. More than four times as many unigenes of the mealy aphid were significantly upregulated on summer host Phragmites australis than on winter host Rosaceae plants...

Erythromelalgia is a rare disorder characterized by burning pain, erythema, and increased temperature typically involving the distal extremities. Although it can progress to involve the face, erythromelalgia presenting only on the face is particularly rare. This disorder is often misdiagnosed when it presents on the extremities and is even more likely to be misdiagnosed when presenting only on the face, delaying appropriate treatment and causing considerable frustration for the patient. We report a case of a 26-year-old woman with erythromelalgia that involved only the face for a number of years and was treated unsuccessfully as rosacea, seborrheic dermatitis, and contact dermatitis...

Hybridization accompanied by polyploidization and apomixis has been demonstrated as a driving force in the evolution and speciation of many plants. A good example to study the evolutionary process of hybridization associated with polyploidy and apomixis is the genus Cotoneaster (Rosaceae), which includes approximately 150 species, most of which are polyploid apomicts. In this study, we investigated all Cotoneaster taxa distributed in a small region of Malipo, Yunnan, China. Based on the morphological characteristics, four Cotoneaster taxa were identified and sampled: C...

FLOWERING LOCUS T (FT) and TERMINAL FLOWER1 (TFL1) proteins share highly conserved amino acid residues but they play opposite regulatory roles in promoting and repressing the flowering response, respectively. Previous substitution models and functional analysis have identified several key amino acid residues which are critical for the promotion of flowering. However, the precise relationship between naturally occurring FT/TFL1 homologs and the mechanism of their role in flowering is still unclear. In this study, FT/TFL1 homologs from eight Rosaceae species, namely, Spiraea cantoniensis, Pyracantha fortuneana, Photinia serrulata, Fragaria ananassa, Rosa hybrida, Prunus mume, Prunus persica and Prunus yedoensis, were isolated...

A cellulolytic bacterium was obtained from the digestive tract of Osphranteria coerulescens. The breakdown of woody and cellulosic substances by this insect may be relative in part to its symbiont bacteria. Under optimal cultural conditions the novel isolate produced 5.35U/ml cellulase after 72h. The enzyme was purified to 36 fold with a 0.59% yield and showed a specific activity of 9.0U/mg. It presented its maximum activity at 60°C and pH 5, while it was stable in a wide range of temperature from 20 to 60°C and pH from 5 to 10...

BACKGROUND: Rosacea is a chronic and common cutaneous condition characterised by symptoms of facial flushing and a broad spectrum of clinical signs. The clinical presentation for rosacea is varied, and there are four primary subtypes, which may overlap - erythrotelangiectatic, inflammatory, phymatous and ocular. It is important to recognise the different subtypes because of the differences in therapy. OBJECTIVE: The objective of this article is to provide evidence-based clinical updates to clinicians, specifically general practitioners (GPs), to assist with their everyday practice, and effective assessment and treatment of rosacea...

The relationship between smoking and rosacea is poorly understood; we aimed to conduct the first cohort study to determine the association between smoking and risk of incident rosacea. We included 95,809 women from Nurses' Health Study II (1991-2005). Information on smoking was collected biennially during follow-up. Information on history of clinician-diagnosed rosacea and year of diagnosis was collected in 2005. We used Cox proportional hazard models to estimate age and multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CI) for the association between different measures of smoking and risk of rosacea...

BACKGROUND: Fungal plant pathogens belonging to the genus Venturia cause damaging scab diseases of members of the Rosaceae. In terms of economic impact, the most important of these are V. inaequalis, which infects apple, and V. pirina, which is a pathogen of European pear. Given that Venturia fungi colonise the sub-cuticular space without penetrating plant cells, it is assumed that effectors that contribute to virulence and determination of host range will be secreted into this plant-pathogen interface...
