Book Description

This Research Topic is part of the Insights in Frontiers in Microbiology series. We are now entering the third decade of the 21st Century, and, especially in the last years, the achievements made by scientists in the field of Microbiology have been exceptional, leading to major advancements. Frontiers has organized a series of Research Topics to highlight the latest advancements in science in order to be at the forefront of science in different fields of research. This specific editorial initiative, led by Dr. Weiqi He, is focused on new insights, novel developments, current challenges, latest discoveries, recent advances and future perspectives in the field. The Research Topic solicits brief, forward-looking contributions from associate editors and review editors that describe the state of the art, outlining recent developments and major achieved accomplishments, future challenges and how to address those challenges to move the field forward. Reviews, Mini-Reviews, Perspectives, and Opinions summarizing the current state and future directions of the field are particularly welcome in this collection.










Recent Advances and Perspectives on the Gastrointestinal Microbiota of Small Ruminants


Book Description

Ruminants are hoofed mammals with a unique digestive system that allows them to better create energy from fibrous plant material than other herbivores. Small ruminants (such as sheep and goats) play an important role in global food security and nutrition, as well as in the livelihoods of farmers and others along the food chain. Due to the unique digestive systems of ruminants, many major studies have focused on the effects of high-concentrate diets on rumen fermentation, ruminal acidosis, and their microbial properties and functions. Therefore, paying attention to the intestinal health of small ruminants during the rapid fattening stage has important implications for their health and productivity. Ruminants host a taxonomically diverse microbiota in their rumen, which is generally considered to be the most efficient natural fermentation system. Rumen microorganisms facilitate the degradation of otherwise indigestible plant fibres into absorbable compounds such as proteins and volatile fatty acids, the main source of energy and nutrition for ruminants. They are composed of a complex and dynamic assembly of bacteria, fungi, archaea, protozoa, and viruses. Diets and additives directly affect the number and viability of rumen microorganisms.













Reviews in the Impact of Gut Microbiota in Health and Disease


Book Description

Frontiers in Microbiology is delighted to present the ‘Reviews in the Impact of Gut Microbiota in Health and Disease’ series of article collections. Reviews in the Impact of Gut Microbiota in Health and Disease will publish high-quality scholarly review papers on key topics in the Impact of Gut Microbiota in Health and Disease. It aims to highlight recent advances in the field, whilst emphasizing important directions and new possibilities for future inquiries. We anticipate the research presented will promote valuable discussion regarding the impact of gut microbiota in health and disease that will translate to best practice applications in clinical, public health and policy settings.




The plant microbiome and its importance for plant and human health


Book Description

The study of plant-microbe associations by new techniques has significantly improved our understanding of the structure and specificity of the plant microbiome. Yet, microbiome function and the importance of the plant’s microbiome in the context of human and plant health are largely unexplored. Comparable with our human microbiome, millions of microbes inhabit plants, forming complex ecological communities that influence plant growth and health through its collective metabolic activities and host interactions. Viewing the microbiota from an ecological perspective can provide insight into how to promote plant health and stress tolerance of their hosts or how to adapt to a changing climate by targeting this microbial community. Moreover, the plant microbiome has a substantial impact on human health by influencing our gut microbiome by eating raw plants such as lettuce and herbs but also by influencing the microbiome of our environment through airflow. This research topic comprising reviews, original and opinion articles highlights the current knowledge regarding plant microbiomes, their specificity, diversity and function as well as all aspects studying the management of plant microbiomes to enhance plant growth, health quality and stress tolerance.
