小麦,一种用途广泛的主食作物,在全球范围内为其谷物广泛种植,准备经历不断增长的需求以维持迅速增长的人口,由于其优越的营养潜力。现代小麦,六倍体物种,通过许多先前倍性的渗入而进化,包括Einkorn,Emmer,Aegilops,和其他人,每个都具有不同的定性和定量特征。科学计量和主题分析是通过测量科学出版物和关键词中表达的知识来定量评估科学研究的有效工具。因此,了解初级小麦驯化事件的研究现状,次要,三级基因库对于提高小麦产量至关重要。在这项研究中,我们分析了从PubMed检索到的数据,以阐明研究现状,并确定了小麦基因组库不同倍性的瓶颈。在过去的三十年中,小麦的出版物趋势经历了指数增长,随着中国成为领先的出版物中心。与在六倍体普通小麦中观察到的发表频率相反,关于Einkorn和Aegilops的学术产出大约少十倍,emmer的出版物少了三倍。这种差异强调了针对这些物种的快速研究计划的优先次序,旨在阐明潜在的生物学特性并优化其育种能力。关键词,如“压力”,\"\"GWAS,\"和\"基因\"是突出的,反映了气候因素对小麦生产的挑战,并通过分子育种和基因操纵来缓解这些挑战。值得注意的是,关键词“einkorn”突出了其作为微调小麦适应过程和质量相关性状的供体的潜力,对现代小麦在不利气候下的生存能力至关重要。相反,Emmer上较高的出版率主要与意大利有关,可能是由于其对四倍体小麦有利的地中海气候。关键词像\"面食\"和\"Ochratoxin,DON\“很普遍,前者来自硬粒小麦,据报道后者在硬粒中的含量高于其他小麦品种,使其不太适合消费。丰富的关键词,如“基因组”和“抗性”强调了Aegilops的关键特征。其他重要关键词,如“Aceriatosichella”,可能表明Aegilops赋予的多个阶段的抗性,而谷物柔软性蛋白质“puroindoline”的存在增强了其对Aegilops捐赠的可接受性。拼写,普通小麦的近亲,每年有成千上万的出版物和丰富的关键词,如“压力”和“产量”,反映了当前科学对小麦研究的重视。此外,诸如“生物防治”和“乳糜泻”之类的分级关键词值得考虑对六倍体小麦的未来研究。
Wheat, a highly versatile staple crop cultivated extensively for its grains on a global scale, is poised to experience increased demand to sustain the burgeoning population, owing to its superior nutritional potential. Modern
wheat, a hexaploid species, has evolved through the introgression of numerous preceding ploidies, including Einkorn, Emmer, Aegilops, and others, each possessing distinct qualitative and quantitative traits. Scientometric and topical analyses serve as effective tools to quantitatively evaluate scientific research by measuring the knowledge expressed in scientific publications and keywords. Thus, comprehending the research status regarding
wheat domestication events within primary, secondary, and tertiary gene pools is paramount for enhancing
wheat production. In this study, we analyze data retrieved from PubMed to elucidate the research status and identify bottlenecks across different ploidy of genomic pools of wheat. The publication trends on
wheat have experienced exponential growth over the past three decades, with China emerging as a leading center for publications. In contrast to the publication frequency observed in hexaploid common wheat, scholarly output concerning Einkorn and Aegilops is approximately tenfold lesser, with emmer trailing behind at three times fewer publications. This discrepancy underscores the prioritization of expedited research initiatives targeting these species, aimed at elucidating latent biological characteristics and optimizing their breeding capabilities. Keywords such as \"stress,\" \"GWAS,\" and \"gene\" are prominent, reflecting the challenges posed by climatic factors on wheat production and their mitigation through molecular breeding and gene manipulation. Notably, the keyword \"einkorn\" highlights its potential as a donor for fine-tuning traits related to wheat adaptation processes and quality, crucial for modern wheat\'s survivability under adverse climates. Conversely, higher publication rates on emmer are primarily associated with Italy, possibly due to its favorable Mediterranean climate for tetraploid wheat. Keywords like \"Pasta\" and \"Ochratoxin, DON\" are prevalent, with the former being derived from durum wheat and the latter being reported in higher amounts in durum compared to other wheat species, rendering it less suitable for consumption. Enriched keywords such as \"genome\" and \"resistance\" underscore the critical characteristics of Aegilops. Other significant keywords like \"Aceria tosichella\" possibly indicate multiple stages of resistance conferred by Aegilops, while the presence of the grain softness protein \"puroindoline\" enhances its acceptability for donation by Aegilops. Spelt, a close relative of common wheat, exhibits a research trend with thousands of annual publications and enriched keywords such as \"stress\" and \"yield\" reflect the current scientific emphasis on wheat research. Furthermore, hierarchical keywords like \"bio-control\" and \"celiac disease\" merit consideration for future research on hexaploid wheat.
