Species-specific PCR-based assays for identification and detection of Botryosphaeriaceae species causing stem blight on blueberry in China

引用

Journal of Integrative Agriculture 2016年第3期15卷 573-579页

作者： XU Cheng-nan ZHANG Hong-jun CHI Fu-mei JI Zhi-rui DONG Qing-long cao Ke-qiang ZHOU Zong-shan Research Institute of Pomology Chinese Academy of Agricultural Sciences College of Plant Protection Agricultural University of Hebei

Botryosphaeriaceae species are important causal agents of blueberry stem blight worldwide. Blueberry stem blight has become an important disease, potentially affecting the quality and production of blueberries in China. It is difficult and time-consuming to identify at the species level using morphological methods. The aim of this study was to develop polymerase chain reaction（PCR） assays for the diagnosis and early detection of latent infections of blueberry stems by Botryosphaeria spp. Species-specific primers, based on the ribosomal DNA internal transcribed spacer region and β-tubulin gene, were designed and selected for use in PCR assays. Three primer pairs, Lt347-F/R for Lasiodiplodia theobromae, Np304-F/R for Neofusicoccum parvum and FaF/Bt2b for Botryosphaeria dothidea, successfully amplified specific PCR fragments of different sizes on pure cultures or from blueberry stems inoculated and naturally infected blueberry plants with three pathogens, respectively. These primers did not amplify any PCR fragments from other blueberry stem disease-associated pathogens, such as Phomopsis spp. and Pestalotiopsis spp. This PCR protocol could detect as low as 1 00 pg to 1 ng of purified fungal DNA. This PCR-based protocol could be used for the diagnosis and detection of these pathogens from pure cultures or from infected blueberry plants.

Chinese Chemical Letters 2024年第4期35卷 187-192页

作者： qiang cao Xue-Feng Cheng Jia Wang Chang Zhou Liu-Jun Yang Guan Wang Dong-Yun Chen Jing-Hui He Jian-Mei Lu College of Chemistry Chemical Engineering and Materials ScienceCollaborative Innovation Center of Suzhou Nano Science and TechnologySoochow UniversitySuzhou 215123China

Waste polyolefin plastics, accounting for 50% of all plastic waste, represent a tremendously unexploited carbon source. Efficiently upcycling polyolefin waste into value-added carbon materials for waste water treatment avoiding using noble metals is challenging but economically and environmentally sustainable. In this work, MAX-Ti_(3)AlC_(2) supported Fe selectively catalyzes polyolefin into few-layered graphene in 5 min under microwave treatment. Graphene and MAX supported Fe(Fe@MLC) can completely(99.9%)degrade chloramphenicol(CAP) within 60 min, retain robust after 10 cycles and work efficiently at a wide p H range(3.87–13.03), avoiding the usage of noble metal. Moreover, the electrochemical active surface area(ECSA) of Fe@MLC is 2.7 times higher than that of commercial Pt/C. This work provides a cheap and efficient catalyst that promotes deconstruction of plastic wastes and indirectly degrades antibiotics thereby realizes the treatment of waste water with waste plastic.

The Sahul Platform where the Sunset-Loxton Shoals and Chuditch gas fields were discovered is located between the Timor Trough to the north and the Malita Graben to the south. These areas are located respectively 440 km and 380 km northwest of Darwin in the northern Bonaparte Basin, Australia. Based on the structural evolution of the northern Bonaparte Basin, data from the wells Loxton Shoals 1, Sunset 1 and Chuditch 1 in the Sahul Platform and Heron 1 in the Malita Graben depocentre, and the Seismic Line N11606 were used to clarify the geological conditions and reconstruct the hydrocarbon accumulation processes in the study area. BasinMod 1-D, 2-D, and 3-D software was used for modeling. The Plover Formation source rock was a poor-to-good hydrocarbon generative potential and reached the middle to late mature oil window in the Sunset-Loxton Shoals field whereas in the Chuditch field, it was an overall fair-to-good hydrocarbon generative potential, and attained the Late mature oil window. The Flamingo, and the Echuca Shoals formations source rocks in the same field were a fair and good hydrocarbon generation potential respectively, and both reached mid-mature oil window. In the Malita Graben depocentre, the Petrel (Frigate) and the Echuca Shoals formations source rocks were a poor-to-very good hydrocarbon generating potential, and had attained wet gas window at the present day. The analyses of organic matter showed that the source rocks in the study area and Malita Graben were gas prone with kerogen types II2 & III and III predominantly. The Middle Jurassic Plover Formation sandstone reservoir in the Sunset-Loxton field was a poor-to-very good quality and potential for gas beds, and it was a very poor-to-very good quality and potential for gas beds in the Chuditch field. The intensities of gas generation and expulsion were more than of oil ones either in the Sahul Platform or in the Malita Graben. The Plover, Petrel (Frigate) and Echuca Shoals formations source rocks

引用

International Journal of Geosciences 2016年第4期7卷 584-597页

作者： Rakotondravoavy Jules Jiaren Ye qiang cao Key Laboratory of Tectonics and Petroleum Resources China University of Geosciences MOE Wuhan China Département des Sciences de la Terre et de l’Environnement à la Faculté des Sciences de Technologies et de l’Environnement de l’Université de Mahajanga Mahajanga Madagascar

The Lynedoch field is located on the west flank of the Calder Graben in the north-eastern Bonaparte Basin, Australia. The data from the wells Lynedoch 1 and Lynedoch 2 and Seismic Line N11809 were used to reconstruct the burial and thermal histories and evaluate the hydrocarbon generated and expelled from the Jurassic to Early Cretaceous source rocks of the study area. Basin Mod 1-D and 2-D softwares were used for modeling. The Upper Jurassic Cleia (Lower Frigate) and Lower Cretaceous Echuca Shoals formations source rocks in the well Lynedoch 1 were a fair-to-good source richness with poor hydrocarbon generating potential, showing kerogen type III and gas prone. The Middle Jurassic Plover Formation source rock in the well Lynedoch 2 was a good organic matter richness with poor hydrocarbon generative potential, the late Middle Jurassic (Callovian) Elang Formation source rock in the same well was a fair source rock with poor hydrocarbon generation potential, and the Lower Cretaceous Echuca Shoals Formation source rock in the same well was a fair-to-very good organic richness with poor-to-fair hydrocarbon generating potential, gas prone with kerogen type III, and reaching wet gas window at present day. These previous formations of the both wells generated oil at the Late Cretaceous and gas at the Early Neogene. But, only Echuca Shoals Formation source rock in the well Lynedoch 2 was able to expelled hydrocarbon at the Middle Paleogene and continued up to present day. This Formation represents fair to slightly good potential source rock in the Lynedoch field.

Frontiers of Optoelectronics 2014年第4期7卷 486-492页

作者： Shenggang WAN qiang cao Changsheng XIE Wuhan National Laboratory for Optoelectronics Wuhan 430074 China School of Computer Science and Technology Huazhong University of Science and Technology Wuhan 430074 China

Long-term digital preservation is an important issue in data storage area. For years, magnetic media based solutions, such as tape and hard disk drive （HDD） based archive systems, monopolize the data archiving market due to their high capacity and low cost. However, in the era of big data, rapidly increasing volume, velocity, and variety of data set bring numerous challenges to the archive systems in various aspects, such as capacity, cost, performance, reliability, power consumption, and so on. In recent years, high capacity optical media, such as bluray discs （BDs） and holographic discs, emerge with the revival of optical storage. Due to the natural simple construction of the optical media, the archive systems based on those optical media, e.g., BD library, demonstrate attractive properties, such as cost per bit, reliability, power consumption, and so on, thus become feasible options in long-term digital preservation. In this paper, we reviewed and compared both the magnetic and optical media based solutions for long-term digital preservation, followed by a summarization on techniques to improve the optical media based archive system.

第四届全国环境与职业医学研究生学术研讨会

作者： cao qiang, SONG Wei-min

[Objective] In order to study the toxicity of PM2.5 to lung. [Methods]: using intratracheally instillation, we expose four groups of rats to PM2.5, and once time per day, and continuously three day. After 24 hours of last exposure, kill rats, examine the Bronchoalveolar lavage fluid (BALF) and analysis the levels of total protein (TP), albumin (ALB), LDH, AKP, MDA and GSH activity. And the lung tissue was taken for HE. [Results]: we have found that the levels of TP, ALB, LDH and AKP in the middle and high dose groups are higher than control and low groups, and the levels of MDA in the high dose group are higher than control. While the levels of GSH in the middle and high dose groups are lower than control and low groups. The results of HE suggest that in the high dose group, the damages of lung are more severe. [Conclusion]: PM2.5 can cause changing of vascular permeability, damages of lung cell and exasperating the oxidative stress in the lung.
