Most plants rely heavily on microbes for survival; both groups gain from these symbioses. A large number of particular genes in plants and microbes are only activated during these interactions, according to research. Various bacteria, of course, can act as pathogens. The plant microbiome, which colonizes all accessible plant tissue, is a varied yet taxonomically structured community of microorganisms found in healthy plants. Plant-microorganism interactions are frequently found on plant surfaces such as leaf cuticles, seeds, and, most notably, roots. Plant Surface Microbiology is primarily concerned with the communication between plants and microorganisms.
The study of biological creatures that are too small to be seen with the naked eye is known as microbiology (without using such tools as the magnifying glass or microscope etc). Microbiology is devoted to investigating the lives and features of a wide range of organisms in their habitats, from bacteria and archaea to parasitic worms. Veterinary microbiology is concerned with bacterial and viral infections of domesticated vertebrate animals that provide food, other useful products, or companionship (livestock, companion animals, poultry, fur-bearing animals, but not fish).
