Four Cucumber mosaic virus (CMV) (CMV-HM 1–4) and nine Tomato mosaic virus (ToMV) (ToMV AH 1–9) isolates detected in tomato samples collected from different governorates in Egypt during 2014, were here characterized. According to the coat protein gene sequence and to the complete nucleotide sequence of total genomic RNA1, RNA2 and RNA3 of CMV-HM3 the new Egyptian isolates are related to members of the CMV subgroup IB. The nine ToMV Egyptian isolates were characterized by sequence analysis of the coat protein and the movement protein genes. All isolates were grouped within the same branch and showed high relatedness to all considered isolates (98–99%). Complete nucleotide sequence of total genomic RNA of ToMV AH4 isolate was obtained and its comparison showed a closer degree of relatedness to isolate 99–1 from the USA (99%). To our knowledge, this is the first report of CMV isolates from subgroup IB in Egypt and the first full length sequencing of an ToMV Egyptian isolate. 相似文献

Influence of stand,site and meteorological variables on the maximum leaf area index of beech,oak and Scots pine 总被引:1,自引:0,他引:1

Different multiple linear regression models of maximum leaf area index (LAImax) based on stand characteristics, site quality, meteorological variables and their combinations were constructed and cross-validated
for three economically important tree species in Flanders, Belgium: European beech (Fagus sylvatica L.), Pedunculate oak (Quercus robur L.) and Scots pine (Pinus sylvestris L.). The models were successfully tested on similar datasets of experimental sites across Europe. For each species, ten homogeneous
and mature stands were selected, covering the species’ entire stand productivity range based on an a priori site index classification.
LAImax was derived from measurements of leaf area index (LAI) made by means of hemispherical digital photography over the whole
growing season (mid-April till end October 2008). Species-specific models of LAImax for beech and oak were mostly driven by management practice affecting stand characteristics and tree growth. Tree density
and dominant height were main predictors for beech, while stand age and tree-ring growth were important in the oak models.
Scots pine models were more affected by site quality and meteorological variables. The beech meteorological model showed very
good agreement with LAI at several European sites. Scots pine’s stand model predicted well LAI across Europe. Since the species-specific
models did not share common predictors, generic models of LAImax were developed for the 30 studied sites. Dominant height was found to be the best predictor in those generic models. As expected,
they showed a lower predictive performance than species-specific ones. 相似文献

Laryngeal saccule eversion has been widely reported as an important component of brachycephalic airway obstructive syndrome (BAOS). The authors hypothesised that saccules affected by acute histological changes in patients showing marked improvement following palate and nares surgery might spontaneously return to normal; moreover, spontaneous resolution of the eversion in patients with fibrotic saccules and/or without clinical improvement following BAOS surgery might be impossible and, on the contrary, the persistence of turbulent airflow and associated ongoing inflammation might lead to aberrant tissue proliferation after resection. In order to demonstrate our hypotheses, the authors decided to perform a unilateral sacculectomy and to postpone and assess the need for the execution of the contralateral saccule resection according to the findings of a second-look laryngoscopy. Ten dogs were enrolled. None of the saccules left in situ underwent spontaneous resolution of the eversion. In one dog, after sacculectomy, proliferation of a soft tissue lesion endoscopically similar to a newly formed saccule occurred. The results of the present study suggest that spontaneous resolution of saccule eversion is uncommon, even after the correction of the primary abnormalities (palate, nares). Resection of the saccules can relieve ventral rima glottidis obstruction; however, secondary intention healing might occasionally result in the recurrence of the obstruction. 相似文献

Climate Change Vulnerability Assessment (VA) tools for forest ecosystems and forest-dependent communities are important for making decisions and understanding the impact of climate change on both social and natural systems. However, the tools are poorly coordinated, making it difficult for policymakers to carry out VAs properly. The aim of this study was to analyze VA literature worldwide to find representative case studies in terms of methods and tools applied and which have been successful in performing VAs on forests and forest-dependent communities. All successful VA studies analyzed had common characteristics such as significant funding, data availability and technical capacity. An additional characteristic was the development of an integrated approach that considered the vulnerability of both ecosystems and communities by combining qualitative and quantitative methods. Community members and relevant stakeholders were significantly involved in a participatory process that concluded with the identification of adaptation measures. The case studies also revealed how policymakers need to choose suitable methods and tools to undertake efficient assessment of vulnerabilities. They need to consider several aspects of the VA process such as subject matter, availability of resources, time and scale. 相似文献

Impact of physicochemical characteristics on the oxidative stability of fish oil microencapsulated by spray-drying 总被引:1,自引:0,他引:1

The aim of the present research was to identify principal parameters determining the oxidative stability of microencapsulated fish oil. Microcapsules were prepared by spray-drying using different types of n-octenylsuccinate-derivatized starch, gum Arabic, sugar beet pectin, sodium caseinate, and/or glucose syrup. Two principal components to classify the different microcapsules accounting for up to 79% of the variance were identified. The principal components were determined by physicochemical parameters reflecting the emulsifying ability of the encapsulant and the drying behavior of the parent emulsion. Microcapsules, which were identified by principal component analysis to be significantly different, exhibited a low stability upon storage, showing that the principal components and, thus, the underlying physicochemical parameters analyzed in the present study are correlated with core material stability. 相似文献
