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 […]
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 […]
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 […]
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 […]
What is the 16S rRNA 16S rRNA (16S ribosomal RNA), is a component of the prokaryotic ribosome 30S subunit. The “S” in 16S is a sedimentation coefficient, that is, an index reflecting the downward velocity of the macromolecule in the centrifugal field. The higher the value, the greater the molecule. The 16S rRNA gene is […]
Microsatellites, also known as simple tandem repeats (STRs), are simple repeat sequences distributing in eukaryotic genomes, which are composed of 2 ~ 6 nucleotide tandem repeats. The repeating times in individual are variable, therefore, the application of microsatellite markers is very extensive. Microsatellite loci is usually amplified by PCR. PCR products are analyzed by electrophoresis […]
Summary: a DNA methylation age inference method, combined with Sequenom MassARRAY technology, can reduce the error of the age to 4.7 years. Age estimation is one of the most important topics in the field of forensic medicine. Especially for juvenile delinquency, highly corrupt bones of the dead and nameless corpse, it can provide the scope […]
Genome-wide association study (GWAS) is a kind of method to detect all or most of the genes among different individuals in specific species and to understand the genetic variation between different individuals. Many susceptibility genes and loci have been found in colorectal cancer using the GWAS method, but there are still many unknown susceptibility genes […]
