AIMS To develop a PCR-based assay for Xanthomonas euvesicatoria detection in culture and in planta. METHODS AND RESULTS A fragment of 1600 bp specific for X. euvesicatoria was found by repetitive extragenic palindromic sequence-PCR. Among the primers designed on the basis of the partially sequenced fragment, the primers Xeu2.4 and Xeu2.5 direct amplification of the expected product (208 bp) f...

The model pathogen Pseudomonas syringae pv. tomato DC3000 causes bacterial speck in tomato and Arabidopsis, but Nicotiana benthamiana, an important model plant, is considered to be a non-host. Strain DC3000 injects approximately 28 effector proteins into plant cells via the type III secretion system (T3SS). These proteins were individually delivered into N. benthamiana leaf cells via T3SS-profi...

Tomato (Solanum lycopersicum L.) is susceptible to many diseases including bacterial speck caused by Pseudomonas syringae pv. tomato. Bacterial speck disease is a serious problem worldwide in tomato production areas where moist conditions and cool temperatures occur. To enhance breeding of speck resistant fresh-market tomato cultivars we identified a race 0 field isolate, NC-C3, of P. s. pv. to...

E-mail addresses: [email protected], cr682003 The SOI transistors permanently offer new candidates as nanodevices. The nothing on insulator NOI transistor was recently derived from the nano SOI–MOSFET family. Their output characteristics were theoretical modelled with an exponential law,...

We report findings from the second phase of a study of co-operative, group-based assessment in Pharmacology for second-year undergraduates at The University of Queensland, Australia. Students (n = 285) enrolled in the 2006 Bachelor of Science degree program completed a group-based assessment task (weighted 10% of their course). Blended teaching strategies and the task design were modified to su...

BACKGROUND Plant-pathogenic begomoviruses have a complex association with their insect vectors. The interactions of begomoviruses and reproduction of their vectors are poorly understood. Bemisia tabaci is known to transmit many begomoviruses, and the spread of B. tabaci, especially the B and Q 'biotypes', has been accompanied by the epidemics of begomoviruses. One of these identified disease-ca...

Crude oil exerts a strong influence on national economy. Changes of international crude oil price have an important effect on Chinese economy because of China’s high dependence on the import of the crude oil. Thus, Chinese stock market can be shocked by the fluctuation of oil price. Reversely, changes in crude oil imports of China have some effect on demands and price of the crude oil. This art...

The aim of this study was to detect polypeptides and genomic regions associated with fruit quality traits in a backcross generation using as parent the Argentinean cultivated tomato Caimanta of Solanum lycopersicum and the wild accession LA722 of S. pimpinellifolium. We tested two types of molecular marker: polypeptide profile (at two ripening stages, mature green and red ripe) and SRAP (sequen...

primary care physicians' visit services for diabetes management are now widely delivered in china's rural public health care. current studies mainly focus on supply but risk factors from patients' view have not been previously explored. this study aims to present the utilization of rural primary care physicians' visit services for diabetes management in the last 12 months in southwestern china,...

Guanxi” is a term in Chinese referring to the reciprocal nature of interpersonal relationships. Its attributes, which are specific to Chinese culture, have been the focus of recent literature. Whereas the impact of guanxi seems to be quite similar to that of general relationships, ties or connections, it is characterized by a number of different dimensions. In this paper, we studied 44 entrepre...
