Biocontrol potential of the endophytic Bacillus amyloliquefaciens YN201732 against tobacco powdery mildew and its growth promotion

Publication date: Available online 28 November 2019Source: Biological ControlAuthor(s): Rong Jiao, Shahzad Munir, Pengfei He, Huanwen Yang, Yixin Wu, Junwei Wang, Yongzhan Cai, Ge Wang, Yueqiu HeAbstractThe effectiveness of Bacillus amyloliquefaciens YN201732, a beneficial endophyte isolated from tobacco seeds was explored for control of tobacco powdery mildew and the systemic resistance mechanisms involved. The results of the study showed that endophyte YN201732 has antagonistic effects on 12 pathogenic fungi. The fermentation broth can inhibit the spore germination and has good control effect on tobacco powdery mildew in the greenhouse. The control effect of the protective test and the therapeutic test at 14 days reached up to 71.09% and 86.11%, respectively. Moreover, endophyte YN201732 can also promote seed germination and seedling plant growth, and improve plant photosynthesis. Compare with water treatment, the root length, plant height, maximum leaf length, leaf width, fresh weight, dry weight, chlorophyll and net photosynthetic rate of tobacco seedlings increased by 32.27%, 86.67%, 154.92%, 107.25%, 664.71%, 207.69%, 150.33%, and 240%, respectively. Additionally, the expression of NPR1 in tobacco leaves was stable when inoculated with YN201732 at different time points, while the PDF1.2 gene was up-regulated rapidly, suggesting that jasmonic acid/ethylene signaling pathway of plant might be induced, which enhance plant resistance to powdery mildew. The chit and PPO...

Discussion and conclusion: Maybe it was a case of drug-induced liver disease, however therapeutic dosages of all administered drugs only once. The mechanisms involved were not investigated, but may be the result of allergic and immunologic aspects caused by ketoprofen and facilitated by a history of hypersensitivity to other NSAIDs as reported by the patient. As for jaundice can be attributed to drug toxicity since laboratory parameters did not reveal any evidence of liver disease. PMID: 32079429 [PubMed - as supplied by publisher]

Authors: Fenizia C, Saulle I, Clerici M, Biasin M Abstract Introduction: Since the identification of HIV, several studies reported the unusual case of small groups of subjects showing natural resistance to HIV-infection. These subjects are referred to as HIV-1-exposed seronegative (HESN) individuals and include people located in different regions of the world, with diverse ethnic backgrounds and routes of exposure. The mechanism/s responsible for protection from infection in HESN individuals are basically indefinite and most likely are multifactorial.Areas covered: Host factors, including genetic background as well...

Conclusion: HIV patients with the disseminated TB have higher risk for ocular TB. As ocular symptoms are rare, still all of them need a detailed ocular examination to look for active ocular TB which will reclassify isolated pulmonary/extrapulmonary to disseminated TB warranting a detailed systemic examination.

Authors: Shi R, Luo Y, Li S, Kong M, Liu X, Yu M, Wu J, Huang L, Yang Z Abstract Background: Kawasaki disease (KD) is an acute systemic vasculitis of unknown etiology. Cyclophilin A (CypA), also known as PPIA, has been identified to play a vital role in the pathogenesis of cardiovascular or inflammatory diseases. However, no studies have examined the relationship between single-nucleotide polymorphisms (SNPs) in the peptidylprolyl isomerase A (PPIA) and the development of KD and KD with or without coronary artery lesions (CALs).Objective: The present study was conducted to evaluate whether PPIA SNPs are associated ...

Conclusions: Our algorithm can be integrated with many other algorithms. In this research, we use only the k-means clustering algorithm with different k values. In future research, we propose several directions: (1) checking the effect of the clustering algorithm to build an ensemble clustering space. (2) Finding poor clustering results based on the training data, (3) reducing the volume of the data by combining similar points based on the EC. Availability and implementation: The KNIME workflow, implementing GrpClassifierEC, is available at https://malikyousef.com. PMID: 32082410 [PubMed]
