关于植物营养生态学

植物营养学与植物生态学发展的前沿交叉正形成了植物营养生态学,植物营养生态学是探讨植物营养利用策略的科学,包括植物体内营养的合理利用策略和植物对无机营养环境的改造以利于营养吸收的各种可能策略。其研究内容主要包括养分利用效率、植物体内营养的再利用、体内营养含量格局和植物对土壤无机营养环境的改造。植物营养生态学以植物种群为研究对象。它的发展对深刻理解种群的生态行为特征具有重要意义,同时对如何增进人工混交群落的营养协调性具有实践上的指导意义。营养生态机理的各个方面是相互协调和相互补充的整体,营养生态机理的效率决定了种群营养合理利用的程度和在营养资源上的竞争力。目前,研究上尚缺少营养策略与其它生态策略的关联性的探讨,随着各种营养策略研究上的深入,这种关联性探讨将成为今后植物营养生态学的主要发展趋势。

流式细胞仪检测高等植物细胞核DNA含量的方法

相对于动物和微生物而言,流式细胞术在植物科学上的应用会因植物组织与细胞(如细胞壁、中央液泡、特殊细胞器等)的特殊结构以及次生代谢产物等特殊成分,造成样品在前期处理、染色及测试等方面的困难,甚至导致检测失败或结果不准确。笔者在长期运用流式细胞仪测试工作中,积累了大量的植物样本检测经验,并参考国内外相关文献,总结出从植物取材、样品制备到植物细胞核DNA流式检测的方法和技巧,可为植物科学研究者及从事流式细胞检测的技术人员提供实验参考。     

Achievement of genetics in plant reproduction research: the past decade for the coming decade

In the last decade, a variety of innovations of emerging technologies in science have been accomplished. Advanced research environment in plant science has made it possible to obtain whole genome sequence in plant species. But now we recognize this by itself is not sufficient to understand the overall biological significance. Since Gregor Mendel established a principle of genetics, known as Mendel's Laws of Inheritance, genetics plays a prominent role in life science, and this aspect is indispensable even in modern plant biology. In this review, we focus on achievements of genetics on plant sexual reproduction research in the last decade and discuss the role of genetics for the coming decade. It is our hope that this will shed light on the importance of genetics in plant biology and provide valuable information to plant biologists.     

Federico Delpino and the foundation of plant biology

In 1867, Federico Delpino, with his seminal work Pensieri sulla Biologia Vegetale (Thoughts on Plant Biology) established plant biology by defining it not in the broad general sense, namely as the science of living beings, but as a branch of natural science dedicated to the study of plant life in relation to the environment. Today, the figure and achievements of this outstanding plant scientist is almost unknown. In the following pages, I will concisely describe the main realizations of Federico Delpino and outline the significance of his work for modern plant science.Key words: Charles Darwin, evolution, history of botany, myrmecophily, plant biology, plant intelligence, plant-insect     

The Gatsby Plant Science Summer School: inspiring the next generation of plant science researchers

We provide evidence from a 5-year study to show that a single concerted effort at the start of undergraduate study can have a clear and lasting effect on the attitudes of students toward plant science. Attendance at a week-long residential plant science summer school in the first year of an undergraduate degree resulted in many students changing courses to include more plant science and increased numbers of graduates selecting plant-based PhDs. The evidence shows that the Gatsby Plant Science Summer School has increased the pool of high-quality plant science related PhD applicants in the UK and has had a positive impact on students' career aspirations. The results are discussed within the context of enhancing the pipeline of future plant scientists and reversing the decline of this vulnerable and strategically important subject relevant to addressing food security and other major global challenges. We have shown that a single well-designed and timely intervention can influence future student behavior and as such offers a framework of potential use to other vulnerable disciplines.

Scientific Theory and Agricultural Practice: Plant Breeding in Germany from the Late 19th to the Early 20th Century

The paper deals with the transformation of plant breeding from an agricultural practice into an applied academic science in the late 19th and early 20th centuries Germany. The aim is to contribute to the ongoing debate about the relationship between science and technology. After a brief discussion of this debate the first part of the paper examines how pioneers of plant breeding developed their breeding methods and commercially successful varieties. The focus here is on the role of scientific concepts and theories in the agricultural innovation process. The second part turns towards the strategies by which agronomists tried to establish plant breeding as an academic discipline and themselves as the new experts for breeding research and varietal development. Again, the focus is on the interplay of scientific theory and agricultural practice. It is argued that in order to better understand the transformation of plant breeding into an applied academic science we have to take different levels into account, i.e. the levels of organizations, individuals and objects, at which science and technology interact.

The science of plant morphology: definition, history, and role in modern biology

As a scientific discipline, plant morphology is 211 yr old, originated by Goethe in 1790. It is a discipline that has largely been Germanic in practice. Because it took its origins from the study of the natural history of plants and the United States is principally an engineering society, the discipline of plant morphology in its pure form has never been widely practiced in this country. What has been labeled "plant morphology" in the United States has served largely as a handmaiden for systematics, using morphological characteristics to carve up diversity into its systematic subunits. Because the heart of plant morphology as a science is a focus on the convergences rather than the homologies in a phylogenetic sense, the German tradition of plant morphology is a unifying science that focuses on fundamental themes that transcend systematic boundaries. This paper traces the history of the science of plant morphology through the lineage of its principal practitioners: Goethe, Hofmeister, von Goebel, and Troll. It also evaluates the principles of plant morphology by applying them to the phyletically diverse Pteridophytes, showing that contemporary members of that group exhibit levels of shoot organization comparable to that of seed plants and discusses the implications of these findings.

Applications of nanobodies in plant science and biotechnology

Key message

Present review summarizes the current applications of nanobodies in plant science and biotechnology, including plant expression of nanobodies, plant biotechnological applications, nanobody-based immunodetection, and nanobody-mediated resistance against plant pathogens.

Abstract

Nanobodies (Nbs) are variable domains of heavy chain-only antibodies (HCAbs) isolated from camelids. In spite of their single domain structure, nanobodies display many unique features, such as small size, high stability, and cryptic epitopes accessibility, which make them ideal for sophisticated applications in plants and animals. In this review, we summarize the current applications of nanobodies in plant science and biotechnology, focusing on nanobody expression in plants, plant biotechnological applications, determination of plant toxins and pathogens, and nanobody-mediated resistance against plant pathogens. Prospects and challenges of nanobody applications in plants are also discussed.

Indian publishing: enduring the boom

There has been a boom in the publication of Indian plant science research in recent years, defying national trends in other sciences and outperforming the international trends in plant science publications. This boom augurs well for India considering the importance of agriculture to her economy and the crucial need for science-based solutions to break the yield barriers. However, sustaining it requires tackling the problems of funding, infrastructure, manpower and other policy issues.     

Bioinformatics: harvesting information for plant and crop science

Bioinformatics is an integral aspect of plant and crop science research. Developments in data management and analytical software are reviewed with an emphasis on applications in functional genomics. This includes information resources for Arabidopsis and crop species, and tools available for analysis and visualisation of comparative genomic data. Approaches used to explore relationships between plant genes and expressed sequences are compared, including use of ontologies. The impact of bioinformatics in forward and reverse genetics is described, together with the potential from data mining. The role of bioinformatics is explored in the wider context of plant and crop science.
