The Impact

Worldwide, plant viruses cause serious reductions in marketable crop yield and in some cases even plant death. In most cases, the most effective way to control virus diseases is through genetically controlled resistance. However, developing virus-resistant (VR) crops through traditional breeding can take many years, and in some cases is not even possible. Because of this, the demonstration of the first VR transgenic plants in 1985 generated much attention. This seminal report served as an inflection point for research in both basic and applied plant pathology, the results of which have dramatically changed both basic research and in a few cases, commercial crop production. The typical review article on this topic has focused on only basic or only applied research results stemming from this seminal discovery. This can make it difficult for the reader to appreciate the full impact of research on transgenic virus resistance, and the contributions from fundamental research that led to translational applications of this technology. In this review, we take a global view of this topic highlighting the significant changes to both basic and applied plant pathology research and commercial food production that have accumulated in the last 30 plus years. We present these milestones in the historical context of some of the scientific, economic, and environmental drivers for developing specific VR crops. The intent of this review is to provide a single document that adequately records the significant accomplishments of researchers in both basic and applied plant pathology research on this topic and how they relate to each other. We hope this review therefore serves as both an instructional tool for students new to the topic, as well as a source of conversation and discussion for how the technology of engineered virus resistance could be applied in the future.

Basic Study

New tools and advanced technologies have played key roles in facilitating basic research in plant pathology and practical approaches for disease management and crop health. Recently, the CRISPR/Cas (clustered regularly interspersed short palindromic repeats/CRISPR associated) system has emerged as a powerful and versatile tool for genome editing and other molecular applications. This review aims to introduce and highlight the CRISPR/Cas toolkit and its current and future impact on plant pathology and disease management. We will cover the rapidly expanding horizon of various CRISPR/Cas applications in the basic study of plant-pathogen interactions, genome engineering of plant disease resistance, and molecular diagnosis of diverse pathogens. Using the citrus greening disease as an example, various CRISPR/Cas-enabled strategies are presented to precisely edit the host genome for disease resistance, to rapidly detect the pathogen for disease management, and to potentially use gene drive for insect population control. At the cutting edge of nucleic acid manipulation and detection, the CRISPR/Cas toolkit will accelerate plant breeding and reshape crop production and disease management as we face the challenges in 21st century agriculture.

The Impact

This paper attempts to study the Nigerian agriculture industry as a panacea to growth as well as an anchor to the diversification agenda of the present government. To do this, the time series data of the four agriculture subsectors of crop production, livestock, forestry and fishery were analysed as stimulus to the Real GDP from 1981-2016 in order to explicate the individual contributions of the subsectors to the RGDP in order to guide the policy thrust on diversification. Using the Johansen approach to cointegration, all the variables were found to be cointegrated. With the exception of the forestry subsector, all the three subsectors were seen to have impacted on the real GDP at varying degrees during the time under review. The crop production subsector has the highest impact, however, taking size-by-size analysis, the livestock subsector could be of much importance due to its ability to retain its value chain and high investment returns particularly in poultry. Therefore, it is recommended that, the government should intensify efforts to retain the value chain in the crop production subsector, in order to harness its potentials optimally through the encouragement of the establishment of agriculture cottage industries. Secondly, the livestock subsector is found to be the most rapidly growing and commercialized subsector. Therefore, it should be the prime subsector to hinge the diversification agenda naturally. Lastly, the tourism industry which is a source through which the impact of the subsector is channeled to the GDP should be developed, in order to improve the impact of such channel to GDP with the sole objective to resuscitate the forestry subsector.

: Nanobionics involves the improvement of plant or plant productivity using nanomaterials. Growth of a plant from a seed encompasses various factors which are directly or indirectly dependent upon the imbibition of micro and macro nutrients and vital elements from the soil. Since most of the nutrition is physiologically unavailable to the plants, it leads to mineral deficiencies in plant and mineral toxicity in soil. Either ways, it is not a favourable situation for the microcosom. The new era of nanotechnology offers a potential solution to the availability of the nutrients to the plants due to its unique chemical and physical properties of nanoparticles. Positive and negative impact of these nanoparticles on seed quality and plant growth varies according to the specific properties of nanoparticles. The present review is an attempt to summarize the impact of nanobionics in agriculture.

The Impact

Drought stress is considered a severe threat to crop production. It adversely affects the morpho-physiological, biochemical and molecular functions of the plants, especially in short duration crops like mungbean. In the past few decades, significant progress has been made towards enhancing climate resilience in legumes through classical and next-generation breeding coupled with omics approaches. Various defence mechanisms have been reported as key players in crop adaptation to drought stress. Many researchers have identified potential donors, QTLs/genes and candidate genes associated to drought tolerance-related traits. However, cloning and exploitation of these loci/gene(s) in breeding programmes are still limited. To bridge the gap between theoretical research and practical breeding, we need to reveal the omics-assisted genetic variations associated with drought tolerance in mungbean to tackle this stress. Furthermore, the use of wild relatives in breeding programmes for drought tolerance is also limited and needs to be focused. Even after six years of decoding the whole genome sequence of mungbean, the genome-wide characterization and expression of various gene families and transcriptional factors are still lacking. Due to the complex nature of drought tolerance, it also requires integrating high throughput multi-omics approaches to increase breeding efficiency and genomic selection for rapid genetic gains to develop drought-tolerant mungbean cultivars. This review highlights the impact of drought stress on mungbean and mitigation strategies for breeding high-yielding drought-tolerant mungbean varieties through classical and modern omics technologies.

AbstractThis article discusses the impact of the COVID-19 pandemic and the Black Lives Matter movement on the arts and cultural sector in the United States, placing the 2020 crises in the context of the United States’s historically decentralized approach to supporting the arts and culture. After providing an overview of the United States’s private, locally focused history of arts funding, we use this historical lens to analyze the combined effects of the pandemic and Black Lives Matter movement on a single metropolitan area – Philadelphia, Pennsylvania. We trace a timeline of key events in the national and local pandemic response and the reaction of the arts community to the Black Lives Matter movement, arguing that the nature of these intersecting responses, and their fallout for the arts and cultural sector, stem directly from weaknesses in the United States’s historical approach to administering the arts. We suggest that, in the context of widespread organizational vulnerability caused by the pandemic, the United States’s decentralized approach to funding culture also undermines cultural organizations’ abilities to respond to issues of public relevance and demonstrate their civic value, threatening these organizations’ legitimacy.

The Impact

This work draws on a combination of three theories, dependency (economics theory), the inner plantation as a socio-psychological construct, and plantation pedagogy (education theory) to develop its own educational theory called edutocracy, as a partial explanation of the failure of the West Indian education system in Barbados. It employs document analysis as its primary method of data collection and analysis and culminates in the construction of a model of edutocracy. Edutocracy reveals how the current West Indian debate surrounding educational reform of the Secondary School Entrance Exam in Barbados and neighboring islands will, like most previous reforms, net little meaningful change if legislators and educators continue to negate the impact of the socio-historical context on education in this region, specifically the deleterious colonial ideologies which continue to shape education for the Afro-West Indian/Barbadian with the interests of the Euro-American metropole as paramount.

The Impact

Climate change, expanding soil salinization, and the developing shortages of freshwater have negatively affected crop production around the world. Seawater and salinized lands represent potentially cultivable areas for edible salt-tolerant plants. In the present study, the effect of salinity stress on plant growth, mineral composition (macro-and micro-nutrients), and antioxidant activity in dune spinach (Tetragonia decumbens) were evaluated. The treatments consisted of three salt concentrations, 50, 100, and 200 mM, produced by adding NaCl to the nutrient solution. The control treatment had no NaCl but was sustained and irrigated by the nutrient solution. Results revealed a significant increase in total yield, branch production, and ferric reducing antioxidant power in plants irrigated with nutrient solution incorporated with 50 mM NaCl. Conversely, an increased level of salinity (200 mM) caused a decrease in chlorophyll content (SPAD), while the phenolic content, as well as nitrogen, phosphorus, and sodium, increased. The results of this study indicate that there is potential for brackish water cultivation of dune spinach for consumption, especially in provinces experiencing the adverse effect of drought and salinity, where seawater or underground saline water could be diluted and used as irrigation water in the production of this vegetable.

AbstractInternational investment law, particularly the global backlash against investment treaties, has evolved recently. This article aims to clarify how international investment law evolved over history, from the early Arab traders in the 7th century to the Ottoman Empire, to understand its hidden aims. It investigates the practice of signing investment treaties, which appear first during the Fatimid Caliphate2 and Mamluk Sultanate3 periods. It then explains when control over foreign investment started to diminish during the Ottoman Empire period.4 Further, it explains the links between the USA Friendship, Commerce and Navigation treaties (FCNs), and current investment treaties, explaining the impact of colonization and imperialism on drafting treaty provisions. Within this historical context, this article illustrates the need to understand the roots of international investment law in order to urge Arab countries to terminate or renegotiate current bilateral investment treaties (BITs) as a number of developing and developed countries have done.
