CRISPR Screen Sequencing, An Innovative Sequencing Technology that Can Facilitate COVID-19 Research

Clustered regularly interspaced short palindromic repeats, or CRISPR, is one of the most phenomenal discoveries that paved the way for modern genome screening and editing technologies. CRISPR is a family of DNA found in the genome of prokaryotes, specifically bacteria and archaea. These sequences contain DNA fragments from known bacteriophages that infect the particular prokaryote. […]

Virus Sequencing, A Handy Method to Facilitate Hepatitis C Virus Research

The Discovery of Hepatitis C Virus Hepatitis, or the inflammation of the liver, is primarily caused by viral infection. Other significant factors to it include alcohol abuse, environmental contaminants, and autoimmune diseases. It became apparent in the 1940s that there were two major forms of contagious hepatitis. In the 1960s, Hepatitis B and A vaccines […]

DNA Microarray vs. High-Throughput Sequencing: A Brief View and the Applications in Gut Microbiome Research

With the advent of the post-genome era, gene chip and next-generation sequencing have become two important branches of biochemistry and molecular biology technologies. DNA microarray, also known as gene chip, is a method characterized by high throughput, high efficiency, and high automation. In a gene chip array, a large number of known probe sequences are […]

Applications of Single-Cell Sequencing Technology in Microbial Ecology

Microbial ecology is the study of the relationships of microorganisms with one another and with their environment. Microbial diversity, distribution, abundance, specific interactions, and their impact on ecosystems are explored. Elected by the scientific journal Nature as one of the technologies to watch for in 2020, single-cell sequencing is a rising technology in single-cell ecology. […]

Plasmid Fact Sheet: Definition, Structure and Application

What is a plasmid? Plasmids are the small circular or linear double-stranded DNA molecules (ranging from a few to several hundred kilobases) found in bacterial cells but also present naturally in archeae and eukaryotes. The plasmids are not packaged inside a chromosome, and have no distinct 5’ or 3’ beginning or end. They can autonomously […]

Microbial Genomics Approaches to Promote Crop Yield

The importance of microbiology in crop yield Plants, bacteria, and fungi have coexisted in soil in a symbiosis for millions of years, and they both benefit greatly from symbiosis. Healthy microbial communities perform a variety of vital ecosystem functions, such as pathogen suppression and regulation of nutrient availability. For example, microorganisms make essential elements such […]

A Summary of Microbial Research in Animals

Why do we need to perform microbial research in animals? Enormous amounts of microorganisms live both within and on animal, the animal and its microorganisms exchange energy substances, transmit information to each other and form a holistic system. The impact of microorganisms on animal health is mainly reflected in mutual benefit sharing and symbiosis. If […]

Why Do We Perform 16S rRNA Sequencing

What is 16S rRNA? 16S ribosomal RNA (or 16S rRNA) is the component of the 30S small subunit of a prokaryotic ribosome, roughly 1500 base pairs. Figure 1A shows how 16S rRNA is involved in a prokaryotic ribosome. The bacterial 16S rRNA gene contains nine hypervariable regions (V1-V9) ranging from 30-100 base pairs, flanked by conserved regions (Figure 1C). You can find […]

18S rRNA and Its Use in Fungal Diversity Analysis

What is 18S rRNA? 18S ribosomal RNA (18S rRNA) is a component of the small eukaryotic ribosomal subunit (40S), and 40S and 60S constitute eukaryotic ribosomes. As a structural RNA for eukaryotic ribosomes, 18S rRNA, the homologue of 16S rRNA in prokaryotes and mitochondria, is thus one of the essential components of all eukaryotic cells. […]

Evolutionary Factors Have Stronger Influence on Gut Microbiome than Diet Patterns

As we all know that gut microbes provide multiple services to host, including digestion. Mammals with special diets, such as carnivores and anteaters, have special gut microorganisms to make it possible for them to eat such food. A common theme in the microbiome field is that the host diet has a significant impact on their […]
