1Endophytes as Producers of Peptides:An Overview About the Recently Discovered Peptides from Endophytic Microbes显示文摘An endophyte is a fungus or bacterium that lives within a plant in a symbiotic relationship.Extensive colonization of the plant tissue by endophytes creates a barrier effect,where they outcompete and prevent pathogenic organisms from taking hold.This happens by producing secondary metabolites that inhibit the growth of the competitors or pathogens.In this way they play a very important role in the plant defence mechanisms.The metabolites produced by these endophytes fall within a wide range of classes of compounds that include peptides which are the focus of this review.Peptides are increasingly being selected for drug development because they are specific for their targets and have a higher degree of interactions.There have been quite a number of endophytic peptides reported in the recent past indicating that endophytes can be used for the production of peptide based drugs.Molecular screening for NRPS,which shows peptide producing capability,has also shown that endophytes are potential producers of peptides.The presence of NRPS also offers the possibility of genetic modifications which may generate peptides with high pharmacological activities.This review,therefore,aims to show the current status of peptides isolated from endophytic bacteria and fungi in the recent decade.Endophytes as potential sources of peptides according to NRPS studies will also be discussed.Muna Ali Abdalla Josphat C.Matasyoh 2014Natural Products and Bioprospecting2014,4,5:5
2Mapping the habitat suitability of Ottelia species in Africa显示文摘Understanding the influence of environmental covariates on plant distribution is critical,especially for aquatic plant species.Climate change is likely to alter the distribution of aquatic species.However,knowledge of this change on the burden of aquatic macroorganisms is often fraught with difficulty.Ottelia,a model genus for studying the evolution of the aquatic family Hydrocharitaceae,is mainly distributed in slow-flowing creeks,rivers,or lakes throughout pantropical regions in the world.Due to recent rapid climate changes,natural Ottelia populations have declined significantly.By modeling the effects of climate change on the distribution of Ottelia species and assessing the degree of niche similarity,we sought to identify high suitability regions and help formulate conservation strategies.The models use known background points to determine how environmental covariates vary spatially and produce continental maps of the distribution of the Ottelia species in Africa.Additionally,we estimated the possible influences of the optimistic and extreme pessimistic representative concentration pathways scenarios RCP 4.5 and RCP 8.5 for the 2050s.Our results show that the distinct distribution patterns of studied Ottelia species were influenced by topography(elevation)and climate(e.g.,mean temperature of driest quarter,annual precipitation,and precipitation of the driest month).While there is a lack of accord in defining the limiting factors for the distribution of Ottelia species,it is clear that water-temperature conditions have promising effects when kept within optimal ranges.We also note that climate change will impact Ottelia by accelerating fragmentation and habitat loss.The assessment of niche overlap revealed that Ottelia cylindrica and O.verdickii had slightly more similar niches than the other Ottelia species.The present findings identify the need to enhance conservation efforts to safeguard natural Ottelia populations and provide a theoretical basis for the distribution of various Ottelia species in Africa.Boniface K.Ngarega John M.Nzei Josphat K.Saina Marwa Waseem A.Halmy Jin-Ming Chen Zhi-Zhong Li 2022Plant Diversity2022,44,5:2
3“一带一路”背景下中非应急防护用纺织品流通关键问题及解决对策显示文摘面对突发性公共卫生问题,国家应急储备和国际防护用品流通均至关重要。为了解非洲国家应急能力,提升应急条件下纺织品的流通效率,文章通过文献梳理、相关人员访问、专家会谈等方式,发现中非国家在新冠肺炎疫情期间防疫用品流通存在一些问题,并对此提出相应对策。中非防疫物品流通过程中的主要问题包括因标准认证差异、产品品质量不达标以及合作形式渠道单一导致的流通障碍。中非国家通过双边或多边标准认可机制、认可中方认证机构、企业生产产品质量预认证、共建信息共享平台和供应能力本地化等措施,可以提高应急条件下产品流通效率,拓宽产品流通渠道,提升中非公共卫生安全。嵇岑 魏元潇 宋琨 丁雪梅 Josphat Igadwa Mwasiagi 2022纺织导报2022,,3:1

7The State of the Kenyan Cotton Growing Industry显示文摘从 1960 年代初到 1980 年代末,种工业的肯尼亚的棉花在农村区域以雇用的预备和财富的创造在肯尼亚的经济起了一个重要作用。它也在在上述提及的时期期间正在繁荣的纺织品工业起了一个中央作用。多年以来,在肯尼亚的棉花生产由 2000 年稳定地掉落了,这个国家经历了严重棉花纤维赤字。这研究被承担调查在肯尼亚种工业的棉花的趋势。象生产,棉花种子分发,棉花陷阱的操作和棉花棉绒的质量的费用一样的工业的选择方面是组织地图(SOM ) 的 considered.Kohonen 自我,聚类技术的 K 工具在数据分析被使用。这研究的结果证明肯尼亚的棉花农民以每公斤的美国 0.31 的收支平衡的价格生产了种子棉花,当提供的价格是每 kilogram.c 的美国 0.29Josphat Igadwa Mwasiagi 黄秀宝 王新厚 JO Wagala 2007Journal of Donghua University(English Edition)2007,24,3:1
