The only known natural example of King's Lomatia (Lomatia tasmanica) found growing in the wild is a clonal colony in Tasmania estimated to be 43,600 years old. [1]A group of 47,000 Quaking Aspen (Populus tremuloides) trees (nicknamed "Pando") in the Wasatch Mountains, Utah, United States, has been shown to be a single clone connected by the root system.
For instance, the bacterial colony is a cluster of identical cells (clones). These colonies often form and grow on the surface of (or within) a solid medium, usually derived from a single parent cell. [2] Colonies, in the context of development, may be composed of two or more unitary (or solitary) organisms or be modular organisms.
Diagram showing bacteria growing and forming into a biofilm on a surface. Colonisation or colonization is the spread and development of an organism in a new area or habitat. Colonization comprises the physical arrival of a species in a new area, but also its successful establishment within the local community.
For example, if a microbiologist observes colonies that resemble a Staphylococcus species, they may perform a catalase test to confirm that it belongs to the genus Staphylococcus, and a coagulase test to determine whether it is a coagulase-negative staphylococcus or a more pathogenic species, such as S. aureus.

An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies.. A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation [1] or small plants like the moss Physcomitrella patens. [2]
For example, filamentous cyanobacteria live in long chains of cells that bundle together into larger structures including biofilms, biomats and stromatolites. [63] [64] These large colonies provide a rigid, stable and long-term environment for
The ammonia is shared with the host plant in the form of organic nitrogenous compounds such as glutamine or ureides. [3] The plant, in turn, provides the bacteria with organic compounds made by photosynthesis. This mutually beneficial relationship is true of all of the rhizobia, of which the genus Rhizobium is a typical example. [4]
The Actinomycetota (or Actinobacteria) are a diverse phylum of Gram-positive bacteria with high GC content. [4] They can be terrestrial or aquatic. [5] They are of great importance to land flora because of their contributions to soil systems. In soil they help to decompose the organic matter of dead organisms so the molecules can be taken up ...
