Potato is a plant that can be influenced by early blight disease. Early blight is one of the most destructive plant diseases, especially in the members of solanaceae family. This disease can reduce yield. Experiment design was a factorial randomized complete design to evaluate the isolate pathogenic Alternaria solani in National Plant gene bank of Iran, during 2008-2009. This experiment was conducted with three replications, and the factors include test methods and three lines 9506, 10908-05 and 10908-18 with genotypes of Agria, Casmos and Desiree (susceptible) and Delta (resistant control). Analysis of variance table was based on the area under the disease progress curve, indicating the effects of the experimental methods;genotype and their interactions are significant at the 1% level. In greenhouse evaluation, the symptoms appeared on, the first day. In this method the area under the curve progression was noted in 10 times, but in vitro method, the symptoms of this evaluation appeared on the first or second day. The Evaluation was carried out after inoculation, and was noted 6 times. The results indicate that genotypes and lines are located in four different groups. In this case, line 9506 and Cosmos were quite sensitive to the surface, and Desiree, is located in a sensitive area. Line 10908-18 and Agria, located approximately at the level of resistance, and line 10908-05 and Delta, have been resistant surface.

Frontiers of Agricultural Science and Engineering 2015年第1期2卷 60-65页

作者： Manosh Kumar BISWAS Peng CHEN Mohamed Hamdy AMAR Xiuxin DENG Key Laboratory of Horticultural Plant Biology (MOE) National Center of Citrus BreedingHuazhong Agricultural University Desert Research Center Egyptian Deserts Gene Bank

Novel Poncirus trifoliata simple sequence repeat(SSR) markers were developed to evaluate their utility for genetic diversity and breeding studies of P. trifoliata and related species. A total of 108 primer pairs were characterized by PCR amplification experiments. Among these, 61 were polymorphic and transferable to other citrus species. The number of alleles per locus ranged from 2 to 6, with an average of 2.37 alleles per locus. The expected heterozygosity and observed heterozygosity ranged from 0 to 0.83 and 0 to 1.00, *** novel polymorphic SSR markers will be useful for citrus cultivar identification and evaluation as well as breeding studies.

The Isolation of Vibrio cholera and Other Enteric Bacteria with Molecular Characterization of Vibrio cholera during the Outbreak of Baghdad/Iraq in 2015

引用

Advances in Microbiology 2016年第9期6卷 699-715页

作者： Sarab K. Jameel Mostafa A. Shafek Ali M. Abdulmohsen Nadira S. Mohamed Sarmad R. Naji Tuhama T. Mohammed AL-Yarmouk Teaching Hospital Baghdad Iraq Department of gene bank University of AL-Nahrain Baghdad Iraq

Vibrio cholera, causing acute watery diarrhea known as cholera disease, affects all ages and both genders. Cholera infection outbreaks in Iraq have been reported for several years. The recent cholera outbreak, emerged throughout 2015, was investigated using bacteriological laboratory tests, singleplex and multiplex PCR technique for the detection of V. cholera from stool samples. Furthermore the toxigenic potential coupled with the antibiotic susceptibility test for cholera and other bacteria were also investigated. The stool samples were collected from 5698 patients admitted to Al-Yarmouk Teaching hospital and health care centers in Baghdad/Al-Karkh, Iraq, from the 1st of August to the 30th of December 2015. The V. cholera was isolated from 194 cases (3.4% of the cases age between 21 - 50 years). In addition, other enteric infections: Salmonellosis and Shigellosis 7 and 21 respectively, protozoan parasite Giardia lamblia and Entamoeba histolytica 2 and 43 cases respectively were also reported. High percentage of V. cholera infection was detected in October (122 cases, 62.8%), compared with other enteric infections that show high percentage of diarrheal disease in September and November. The results have confirmed that the cholera outbreak was caused by V. cholera O1, biotype El Tor, and serotype Inaba. Seven virulence genes were identified ctxA, toxR, zot, ace, rfbO1, tcpA and ompW. Moreover, the cholera isolated strains were found sensitive to most antibiotic but resistant to nalidixic acid.

Phospholipase D antagonist 1-butanol inhibited the mobilization of triacylglycerol during seed germination in Arabidopsis

引用

Plant Diversity 2018年第6期40卷 292-298页

作者： Yanxia Jia Weiqi Li Germplasm bank of Wild Species Kunming Institute of Botany Chinese Academy of Sciences

Storage oil breakdown plays an important role in the life cycle of many plants by providing the carbon skeletons that support seedling growth immediately following germination. 1-Butanol, a specific inhibitor of phospholipase D(PLD)-dependent production of the signalling molecule phosphatidic acid(PA), inhibited Arabidopsis seed germination. N-Acylethanolamines(NAEs), which have been shown to inhibits PLDa1 activity, have no effect on seed germination. However, mobilization profile of triacylglycerols(TAG) that induced by each compound has not been reported. To gain deeper insights into the mode of mobilization of TAG during NAE 12:0 or 1-butanol treatment, we conducted a detailed comparative analysis of the effect of NAE 12:0, DMSO, 1-butanol and tert-butanol on Arabidopsis seed germination and fatty acid composition, tert-butanol and DMSO served as the corresponding controls treatment respectively. Our data show that 1-butanol, but not the inactive tert-butanol isomer, inhibited Arabidopsis seed germination, which is accompanied by a with retardation of the mobilization of triacylglycerols(TAG). In contrast, NAE 12:0 did not affect mobilization of TAG, nor did it significantly delay seed germination as monitored by radicle and cotyledon emergence. 1-Butanol induced RNA degradation in seeds and seedlings. We speculate that the large-scale degradation of RNA under the induction of 1-butanol may lead to abnormal gene expression in genes necessary for seed germination, including the genes needed for the mobilization of oil bodies, and thus cause a delay of seed germination. To the best of our knowledge, we report for the first time that 1-butanol delays the mobilization of TAG.

Dear Editor,Reproductive isolation is both the indicator and a primary force of speciation, and plays a key role in maintaining species identity. Understanding the origin and mechanisms of reproductive isola- tion is of fundamental importance in evolutionary biology. In recent years, a number of genes that induce reproductive barriers have been identified in several model organisms such as Drosophila, rodents, yeast, Arabidopsis.
