Plant Proteomics, Microbial and Animal Proteomics

Proteomics is a method for determining the composition and abundance of a group of proteins, referred to as a proteome, in a biological sample specified by space (tissue type, cells, or organelles) and time (developmental stage or following a particular external stimulus). In addition to protein identification, proteomes can be quantified for posttranslational modifications or at the subcellular level, which is information that transcriptomes cannot provide. Expanding the proteome coverage to enable for the detection of low abundant proteins is critical for inferring biological meaning from proteomic data.

Due to their destructive nature, microbial diseases are becoming global hazards to human health. Protein and genome-level analysis are more essential than traditional analysis in controlling these infections. Large genomic datasets are revolutionizing both our understanding of microbiology and the way we explore the organisms that interest us as microbiologists. The explosion of genetic information has rejuvenated systems biology, and proponents now strive to explain large biological systems in terms of their molecular components and interconnections. Microorganisms are thus ideal candidates for systems biology research, and the discipline of systems microbiology is predicted to yield tools and approaches with broad application across the life sciences.    

Proteomics is the study of the proteins found in a specific tissue or fluid (the proteome). It is crucial to a variety of scientific fields, including animal and veterinary sciences. Despite this, animal scientists have been constrained in their use of proteomics for a variety of reasons, including cost, a lack of adequate genomic data from many species of interest, and a lack of knowledge of the technology's potential. Despite its considerable scientific promise, animal proteomics remains a limited field of study. Veterinary-related health issues, experimental disease and pathogenic investigations, laboratory animal studies, medication testing, and understanding genotype–phenotypes are all examples of animal proteomics. Animal proteomics can also be used to quickly analyse parameters for animal product-related regulatory issues like meat testing, milk proteins, and other bodily fluids like saliva and sera. The existence of various abundant proteins such as albumins and globulins, which were assumed to generally interfere with the detection of less abundant proteins, is one of the primary problems in animal proteomics.
