Nowadays,
many biological terms receive new interpretations,
especially the concept of species. The species is
the main structural unit of living things. It emerges,
develops, and, when living conditions change either
disappear or transforms into other species. There
is no clear and unified definition of species. The
achievements of contemporary molecular genetic studies
indicate that the majority of microorganisms exist
mainly not in a free-floating condition, but in
formed associations or consortia. Microbial interactions
occur by transferring molecular and genetic information,
and various mechanisms such as secondary metabolites,
siderophores, quorum-sensing system, biofilm formation,
and cell transduction signals can be involved in
this exchange. Therefore, for a deeper understanding
of the concept of "species" in biology,
it is necessary to take into account not only morphological
and physiological criteria, but also to consider
species from the viewpoint of systems biology, and
to bear in mind factors of horizontal gene transfer.
Therefore, the concept of "species" can
be considered in a broader context, in particular
within ecosystems with all assimilation relations. |
