1苦苣苔科植物Lysionotus bijantiae的名实订正显示文摘通过查阅相关文献和标本,作者发现近期发表的苦苣苔科吊石苣苔属植物一新种——Lysionotus bijantiae D. Borah&A. Joe实为鉴定错误,应是汉克苣苔属的长圆叶汉克苣苔\[Henckelia oblongifolia (Roxb.)D. J. Middleton&Mich. M?ller\]\[原长圆叶唇柱苣苔Chirita oblongifolia (Roxb.) Sinclair\]。Lysionotus bijantiae的模式标本采集于中国西藏东南部地区的喜马拉雅南坡,该地区苦苣苔植物多样性较为丰富。作者因其花具2枚发育雄蕊而将其归于吊石苣苔属,花萼分裂不达基部而与吊石苣苔属其他相关种类比较,而忽略了其种子先端不具附属物的特征。通过电镜扫描观察到,该种在墨脱境内居群以及其模式产地居群的种子均无附属物,从而证实了该种不是吊石苣苔属的物种,而是属于汉克苣苔属。因此,作者将Lysionotus bijantiae处理为Henckelia oblongifolia的新异名,同时提供了长圆叶汉克苣苔的彩色图片(含种子扫描图)、选定模式标本,并给出了吊石苣苔属和汉克苣苔属的区分方法和主要识别特征,不仅为这两个属的物种鉴定提供了参考,而且避免更多的物种分类混淆问题出现。蔡磊 BORAH Dipankar 刀志灵 温放 2020广西植物2020,40,10:4
2有机化学课程全英语教学的探索与思考显示文摘顺应高等教育国际化的形势,本科生的全英文教学是我校近几年进行的重要教学改革与创新。在有机化学课程全英语教学改革试验中,从学生的实际出发,我们选择了合适的全英文原版教材,也大胆地尝试了新的教学模式。同时,我们探讨了全英教学过程中存在的问题及解决的对策。在近一年的教学实践中,学生获取了有机化学相关知识,也锻炼和提高了英语表达能力。严国兵 Arun Jyoti Borah 2014广州化工2014,42,23:4
3Assessing the relationship between the rumen microbiota and feed efficiency in Nellore steers显示文摘Background:Ruminants rely upon a complex community of microbes in their rumen to convert host-indigestible feed into nutrients.However,little is known about the association between the rumen microbiota and feed efficiency traits in Nellore(Bos indicus)cattle,a breed of major economic importance to the global beef market.Here,we compare the composition of the bacterial,archaeal and fungal communities in the rumen of Nellore steers with high and low feed efficiency(FE)phenotypes,as measured by residual feed intake(RFI).Results:The Firmicutes to Bacteroidetes ratio was significantly higher(P<0.05)in positive-RFI steers(p-RFI,low feed efficiency)than in negative-RFI(n-RFI,high feed efficiency)steers.The differences in bacterial composition from steers with high and low FE were mainly associated with members of the families Lachnospiraceae,Ruminococcaceae and Christensenellaceae,as well as the genus Prevotella.Archaeal community richness was lower(P<0.05)in p-RFI than in n-RFI steers and the genus Methanobrevibacter was either increased or exclusive of p-RFI steers.The fungal genus Buwchfawromyces was more abundant in the rumen solid fraction of n-RFI steers(P<0.05)and a highly abundant OTU belonging to the genus Piromyces was also increased in the rumen microbiota of highefficiency steers.However,analysis of rumen fermentation variables and functional predictions indicated similar metabolic outputs for the microbiota of distinct FE groups.Conclusions:Our results demonstrate that differences in the ruminal microbiota of high and low FE Nellore steers comprise specific taxa from the bacterial,archaeal and fungal communities.Biomarker OTUs belonging to the genus Piromyces were identified in animals showing high feed efficiency,whereas among archaea,Methanobrevibacter was associated with steers classified as p-RFI.The identification of specific RFI-associated microorganisms in Nellore steers could guide further studies targeting the isolation and functional characterization of rumen microbes potentially important for the energy-harvesting efficiency of ruminants.Déborah Romaskevis Gomes Lopes Márcio de Souza Duarte Alex J.La Reau Ibrahim Zuniga Chaves Tiago Antônio de Oliveira Mendes Edenio Detmann Cláudia Braga Pereira Bento Maria Eugênia Zerlotti Mercadante Sarah Figueiredo Martins Bonilha Garret Suen Hilário Cuquetto Mantovani 2021Journal of Animal Science and Biotechnology2021,12,4:3
4新型蛋白质中的氨基酸(综述)显示文摘氨基酸(Amino Acid,AA)是所有动物体内蛋白质的基本构架,在细胞中起着多重调节功能。对猪而言,AA分两大类:必需氨基酸(Essential Amino Acid,EAA)和非必需氨基酸(Non-Essential Amino Acid,NEAA)。EAA无法在动物的生理系统内自然合成,因此EAA必须通过日粮提供给动物;而NEAA则可在动物体内合成,因此无需在日粮中额外添加。在单胃动物所需的20种AA中(表1),猪的EAA仅为9种(蛋氨酸、组氨酸、苯丙氨酸、亮氨酸、异亮氨酸、苏氨酸、色氨酸、赖氨酸和缬氨酸)。这种不可缺少的AA因动物物种的不同也有所不同。韩浩月(译) 夏俊花(审) 罗静如(制图) Sanjib Borah Dipankar Paul 2018国外畜牧学(猪与禽)2018,38,1:3
5Investigation of phytosociological parameters and physicochemical properties of soil in tropical semi-evergreen forests of Eastern Himalaya显示文摘The study of floral diversity in forest and its development are incomplete without taking consideration of plant-soil interactions. So with this view in mind, the present study was conducted in tropical semi-evergreen forests of the Mokukchung district, Nagaland, in eastern Himalaya. The aim of the study was to investigate the phytosociological parameters in relation to soil properties.Seven sites were randomly selected to study the soil properties at up to one meter in depth and a phytosociological study was carried out in nearby areas via the quadrate method. In the studied sites, the richness of tree species varied from 4 to 15 ha^(-1), with Gmelina arborea and Duabanga grandifloras being the common species.The highest total basal area was recorded in 10 mile village(47,998.16 cm^2ha^-1)) followed by Minkong village site(32,704.66 cm^2ha^(-1)). Soil physical and chemical properties—i.e. bulk density(BD), soil p H, organic carbon(OC),available nitrogen(N), available phosphorus(P), and available potassium(K) were analyzed using standard procedures. Significant differences were observed in the soil properties. The basal area of species showed significant positive correlation in terms of available K(0.754) and OM(0.302) content in soil, and the Shannon–Wiener diversity index(H) is also positively correlated with the available N content(0.402). The undisturbed nature of the sites played an important role in maintaining the soil fertility and floral diversity of the sites. Moreover, sites with maximum productivity and soil fertility are considered as potential carbon sequestration areas in the region while sites with the low soil fertility need restoration.Gaurav Mishra P.K.Das Rinkumoni Borah Antara Dutta 2017Journal of Forestry Research2017,28,3:3
