Understanding microfungal diversity - A critique
(2007-12-01)
Hyde, Kevin D.
;
Soytong, Kasem
This paper reviews recent advances in understanding microfungal diversity. It questions the large amounts of funding given to molecular phylogenetics despite the fact that we barely know more than a small percentage of the global fungi. It also questions the practice of sequencing fungal strains from culture collections, as they may be wrongly identified and usually lack any herbarium specimens to check characters against. The need for epitypification with living specimens is vindicated. Host fungi relationships have been shown to be important to our knowledge of fungal numbers and research on fungi on various hosts are outlined. Data on the fungi from extreme environments, endophytes and aquatic fungi have advanced the knowledge of fungal diversity, while recommendations that funding bodies should fund basic research are expressed. © 2007 Adac.

Strains’ improvement technology plays an essential role in enhancing the quality of industrial strains. Several traditional methods and modern techniques have been used to further improve strain engineering programs. The advances stated in strain engineering and the increasing demand for microbial metabolites leads to the invention of the genome shuffling technique, which ensures a specific phenotype improvement through inducing mutation and recursive protoplast fusion. In such technique, the selection of multi-parental strains with distinct phenotypic traits is crucial. In addition, as this evolutionary strain improvement technique involves combinative approaches, it does not require any gene sequence data for genome alteration and, therefore, strains developed by this elite technique will not be considered as genetically modified organisms. In this review, the different stages involved in the genome shuffling technique and its wide applications in various phenotype improvements will be addressed. Taken together, data discussed here highlight that the use of genome shuffling for strain improvement will be a plus for solving complex phenotypic traits and in promoting the rapid development of other industrially important strains.

Advances in the phylogenesis of Agaricales and its higher ranks and strategies for establishing phylogenetic hypotheses

We present an overview of previous research results on the molecular phylogenetic analyses in Agaricales and its higher ranks (Agaricomycetes/ Agaricomycotina/Basidiomycota) along with the most recent treatments of taxonomic systems in these taxa. Establishing phylogenetic hypotheses using DNA sequences, from which an understanding of the natural evolutionary relationships amongst clades may be derived, requires a robust dataset. It has been recognized that single-gene phylogenies may not truly represent organismal phylogenies, but the concordant phylogenetic genealogies from multiple-gene datasets can resolve this problem. The genes commonly used in mushroom phylogenetic research are summarized. © Zhejiang University and Springer-Verlag GmbH 2008.

Plants are essential biotic components of Earth that sustain life by producing food, regulating the environment, and transferring energy within ecosystems. Over the past decade, substantial progress in plant science and agricultural technology has transformed traditional agricultural systems, increasing agricultural productivity, improving resource-use efficiency, and promoting sustainable practices. Innovations in machinery, seed improvement, irrigation management, and fertilizer optimization have significantly enhanced crop yields and land-use efficiency over the past five decades. Agriculture is gradually adopting new technologies (robotics, stack-gene technology, three-dimensional bioprinting, and global positioning system–enabled precision farming) to increase productivity while reducing environmental impacts and addressing labor shortages. Emerging technologies such as artificial intelligence, CRISPR/Cas9 (where CRISPR and Cas9 denote clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9, respectively) gene editing, nano-bionics, vertical farming, and farming in space have the potential to maximize resource use, improve resilience to climate change, and ensure the continued sustainability of food production. This review examines current technological trends in agriculture and plant sciences, emphasizing their contributions to agricultural productivity, environmental sustainability, and the socioeconomic well-being of farmers. It also examines how these technologies could be used to address future global food security and environmental sustainability challenges.

Fish gut microbiota: a source of novel metabolites – A review article

Similar to human beings, fish harbor microorganisms in their gastrointestinal tract (GIT). Fishes are diverse groups of gut microbiota, including protists, fungi, yeasts, viruses, bacteria, and archaea. In addition to serving as a barrier against infections, these microbes that inhabit the gastrointestinal tract of fish play a role in nutrition, physiology, immunity, and life span. All fish have gut microbiota; however, the makeup of these communities varies depending on the fish's life stages, the habitat they live in, their nutrition, the seasons, their trophic level, etc. For both recreational and commercial fisheries, it is crucial to comprehend the bacterial make-up of fish microbiomes. The gut microbiota aids in the development of methods for modifying the gut microbiota of the target fish species to enhance aquaculture quality. These gut microbes are an invaluable, essential source of novel, promising bioactive compounds with significant biological activity. The natural product secondary metabolites from specific strains of Chaetomium spp. may develop to be biomedicine for sustainable protection. This review provides a comprehensive knowledge of the composition of the gut microbiota of fish, their development, changes in the living environment, their modification, and their applications.
