Plant Microbiome

The plant microbiome, like the plant, influences the processes that lead to plant development, health, and crop productivity. Cassava is a perennial herbaceous plant native to South America that has been cultivated for centuries as a staple food throughout the world. Not only is cassava a good source of carbohydrates, but it also has a high tolerance for a variety of phenotypic conditions, and the majority of cassava plants are susceptible to a variety of diseases. Thus, using cassava as a model, this chapter discusses the plant microbiome. We discuss the structure and function of the microbiome, as well as the technique for studying microbiomes. Additionally, we conducted a systematic review of references pertaining to the microbiome of the cassava plant using cultivation-dependent or cultivation-independent methods. Numerous significant genera of bacteria and fungi are found in cassava’s phyllosphere and rhizosphere, including groups of gram-negative bacteria, gram-positive Actinobacteria, and gram-positive non Actinobacteria. Additionally, we identified critical organisms in the phyllosphere and rhizosphere. Cassava endophytes also produce antifungal secondary metabolites such as pumilacidins and surfactin. The investigation of their phenotypes and interactions with the cassava plant will aid in increasing productivity.

AbstractThe dispute settlement system of the World Trade Organization (the "WTO") presents a number of innovative features within the various models of international justice existing at the turn of the millennium. Ten years after its establishment, it is worthwhile to examine its key features in the light of a comparative analysis, exploring its strengths and weaknesses, and highlighting aspects of general interest and possible developments.

Competence in English pragmatics enhances the use of English in social contexts throughout the world. However, using English as a second language is always problematic particularly when it comes to the interpretation of speech act in English. The differences in structure and function between English and other languages such as Tshivenda are conspicuous. The current research explored Speech Act of English and Tshivenda representatives and directives among the Tshivenda-speaking people. The findings revealed that the Tshivenda-speaking people faced difficulties utilising English Speech Acts such as representatives, and directives. The research recommends frequent interaction between those proficient in English and Tshivenda-speaking people.

Digital technologies mediate engagement with the world by making activities visible. The automaticity and physicality of the ways in which they do this suggest that it could be productive to view them as responsive digital materials. This paper explores the structure and function of responsive materials in order to develop a conceptualization of responsive digital materials. It then begins to unpack the complexities of digital material mediation through both drawing on and extending existing postphenomenological theory.

The emergence of severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) and the subsequent COVID-19 pandemic has significantly impacted the world not just with disease and death but also economic turmoil. The rapid development and deployment of extremely effective vaccines against SARS-CoV-2 has made the end of the pandemic a reality within reach. However, as the virus spreads it has acquired mutations; and thus, variants of concern have emerged that are more infectious and reduce the efficacy of existing vaccines. While promising efforts are underway to combat these variants, the evolutionary pressures leading to these variants are poorly understood. To that end, here we have studied the effects of three amino-acid substitutions on the structure and function of the SARS-CoV-2 spike glycoprotein receptor-binding domain found in several variants of concern such as B.1.1.7, B.1.351 and P.1 that are now circulating. We found that these substitutions alter the RBD structure and stability, as well as its ability to bind to ACE2, which may have opposing and compensatory effects. These findings provide new insights into how these Variants of Concern (VOC) may have been selected to optimize infectivity while maintaining the structure and stability of the receptor binding domain.

Computer simulation is an important research tool in today’s scientific world. Computers allow us to perform computations that mimic the behavior of complex (biological) systems in ways that we could not otherwise achieve. You could think of these simulations as a computer game, in which a virtual world is created that works according to certain (e.g., physical) rules. While we play the game, we learn the rules governing this virtual world and its environment, and also the way that we affect this world as players. In this article, I will explain how we use computer simulations in the world of structural biology to study the structure and function of molecules. I will also describe how I think that we could use insights from the world of biology and computer simulations to advance the society that we live in.
