| 1 | 蓖麻高光效种质的筛选显示文摘【目的】研究蓖麻不同种质的光合特性,为蓖麻高光效种质的筛选及利用提供参考。【方法】结合主成分分析与系统聚类分析等方法,对29份来自不同地区的蓖麻种质胞间CO_(2)浓度(Ci)、蒸腾速率(Tr)、气孔导度(Gs)、净光合速率(Pn)、叶片瞬时水分利用效率(WUE)和蒸腾效率(TE)6个光合参数综合评价,筛选出优异蓖麻种质。【结果】6个光合参数的变异系数范围为16%~35%。其中,Pn与Gs的变异系数最高、达35%;Ci的变异系数最低、为16%。相关性分析中,Pn与Ci呈极显著负相关,与Tr和WUE均呈极显著正相关。主成分分析结果表明,3个主成分可以解释6个光合相关参数的99.15%,3个主成分可称为光合因素、气孔因素和水分因素。光合参数聚类分析将29份蓖麻种质划分为4个类群。其中第Ⅱ类包括4个材料,占总材料数的13.79%,这些材料净光合速率最高,均超过整体材料净光合速率的平均值,且本类群中的Pn、Gs和Tr均处于较高水平。筛选出YSL-5、SD-21、A40-7、B11-1等4个材料作为适合育种需要的高光效蓖麻种质。【结论】Pn高、Gs大、WUE相对较高的一类种质可作为蓖麻高光效品种选育的中间材料加以利用。 | 顾帅磊 陆建农 杨婷 Akwasi Yeboah 李东娜 曾泳怡 殷学贵 | 2021 | 广东农业科学2021，48，5： | 4 |
| 2 | Drugging in the absence of p53显示文摘Inactivation of the p53 gene is a key driver of tumorigenesis in various cancer cohorts and types.The quest for a successful p53-based therapy that holds the promise of treating more than half of the cancer population has culminated in extensive knowledge about the role and function of p53 and led to new proposed innovative strategies against p53-defective cancers.We will discuss some of these latest studies with a focus on metabolic regulation and DNA damage response and also highlight novel functions of p53 in these pathways that may provide a contemporary rationale for targeting p53 loss in tumors. | Obed Akwasi Aning Chit Fang Cheok | 2019 | Journal of Molecular Cell Biology2019，11，3： | 4 |
| 3 | Flesh Color Diversity of Sweet Potato: An Overview of the Composition, Functions, Biosynthesis, and Gene Regulation of the Major Pigments显示文摘Sweet potato is a multifunctional root crop and a source of food with many essential nutrients and bioactive compounds.Variations in the flesh color of the diverse sweet potato varieties are attributed to the different phytochemicals and natural pigments they produce.Among them,carotenoids and anthocyanins are the main pigments known for their antioxidant properties which provide a host of health benefits,hence,regarded as a major component of the human diet.In this review,we provide an overview of the major pigments in sweet potato with much emphasis on their biosynthesis,functions,and regulatory control.More-over,current findings on the molecular mechanisms underlying the biosynthesis and accumulation of carotenoids and anthocyanins in sweet potato are discussed.Insights into the composition,biosynthesis,and regulatory control of these major pigments will further advance the biofortification of sweet potato and provide a reference for breeding carotenoid-and anthocyanin-rich varieties. | Hanna Amoanimaa-Dede Chuntao Su Akwasi Yeboah Chunhua Chen Shaoxia Yang Hongbo Zhu Miao Chen | 2020 | Phyton-International Journal of Experimental Botany2020，89，4： | 2 |

| 8 | A comprehensive review of the effects of biochar on soil physicochemical properties and crop productivity显示文摘Intensive land use has several detrimental effects on land function and imposes an undue burden on the environment.Continuous farming and pollution by heavy metals have negatively influenced many soils.Biochar is now gaining attention as a major research subject in the areas of agriculture,environment,and energy as an eco-friendly soil conditioner.The use of biochar for agricultural and environmental purposes has been widely studied and reviewed.Unfortunately,there are few reviews on biochar structures and other biochar uses.This review presents an overview of current developments in the effects of numerous biochar physicochemical properties and biochar uses,such as utilization as a soil microbial activity,contaminant adsorbent,ion exchange,soil amendment,gas storage and water retention.The physical,chemical and biological properties have been discussed following amendments to the soil and conditions of preparation.However,scientific observation and research are required to identify the negative effects of biochar in preparations and applications.It is envisaged that further in-depth studies of biochar amendment will lead to a deeper understanding of biochar's relationships with soils and that reviews of the negative impacts of biochar could reveal ways in which they might be mitigated. | Ammal Abukari James Seutra Kaba Evans Dawoe Akwasi Adutwum Abunyewa | 2022 | Waste Disposal and Sustainable Energy2022，4，4： | 1 |

| 16 | RecGuard: An efficient privacy preservation blockchain-based system for online social network users显示文摘Recommendation systems provide ease and convenience for users to address information overload problems while interacting with online platforms such as social media and e-commerce.However,it raises several questions about privacy,especially for users who prefer to remain anonymous,especially on online social networks(OSNs).Moreover,due to the commercialization of online users'data,some service providers sell users'data to third parties at the blind side of the users,which leads to trust issues between users and service providers.Such matters call for a system that gives online users much-needed control and autonomy of their data.With the advancement of blockchain technology,many research institutions are experimenting with decentralized technologies to resolve the OSN user dilemma of privacy intrusion against third parties and hacks.To resolve these limitations,we propose RecGuard,a privacy preservation blockchain-based network system.We developed two smart contracts,RG-SH and RG-ST,to ensure the security and privacy of user data.The RG-SH manages user data,whereas the RGST stores data.A graph convolutional network(GCN)was integrated with the blockchain-based system to detect malicious nodes.Finally,we implemented our framework prototype on a locally simulated network.The analysis and experiment results show that the proposed scheme demonstrates the effectiveness and privacy of users in our framework. | Samuel Akwasi Frimpong Mu Han Edward Kwadwo Boahen Rexford Nii Ayitey Sosu Isaac Hanson Otu Larbi-Siaw Isaac Baffour Senkyire | 2023 | Blockchain(Research and Applications)2023，4，1： | 0 |
| 17 | 蓖麻骨干亲本杂种优势群的划分显示文摘为提高蓖麻种质的鉴别和利用效率,本研究利用简单重复序列标记(simple sequence repeats,SSR)对来自10个国家15个地区的101份蓖麻骨干亲本材料进行了杂种优势群的划分。结果显示:58对SSR标记在101份蓖麻骨干亲本材料中共检测出328个等位基因,平均每个位点的等位基因数为5.655个;Shannon’s信息指数(I)的范围为0.916~1.939,平均值为1.469;平均多态性信息含量(PIC)为0.732,变幅为0.377~0.894。有效等位基因数(Ne)、观测杂合度(Ho)和期望杂合度(He)分别为3.941、0.817和0.732。利用UPGMA方法在遗传相似系数为0.462时将101份蓖麻骨干亲本划分为5个大群8个亚群。分群结果显示,大部分试验材料表现出很强的地域性,来自同一个国家或地区的材料往往聚为一类。来自15个不同地区蓖麻材料的群间遗传距离介于0.122~0.936,平均为0.508,遗传一致度在0.312~0.885范围内,平均为0.606。其中,来自广东和山东的蓖麻材料的遗传距离最小,遗传一致度最高,亲缘关系较近。本研究在分子水平上为蓖麻亲本选配等工作提供了科学依据。 | 顾帅磊 陆建农 杨婷 Akwasi Yeboah 李东娜 谢钰 刘海燕 殷学贵 | 2022 | 分子植物育种2022，20，22： | 0 |
| 18 | Coinage in Akan Among Senior High School Students:A Case Study of Selected Schools in Ghana显示文摘The paper is entitled“Coinage in Akan Among Senior High School Students”.It aims to investigate coinage used by senior high school students.This paper also investigates other word formation processes involved in coined words and the reasons why the students use them in their everyday conversation.The collected data from direct elicitation and interviews were categorized into the types of coined words and analyzed in terms of their formation processes by using a method of analysis based on theories as proposed by Yule(1985),Potter(1975),O’Grady and Guzman(1996),and Gerber(1968).The findings show that there are 10 groups of word formation processes in this study.This paper presents a qualitative analysis of the findings of a sociolinguistic survey geared towards coinage as used by students of both Osei Tutu Senior High School and Bisease Community/Senior High School speech communities.It is also imperative to state that these two schools are located in typical Akan speaking communities.Osei Tutu Senior High School,situated in Akropong,in the Ashanti region of Ghana,is a single sex school(boys’school)and Bisease Community/Senior High School on the other hand is situated in Ajumako-Bisease in the central region.The latter is a mixed school. | Samuel Akwasi Konney | 2023 | Sino-US English Teaching2023，20，7： | 0 |
