Circadian Advantage
A circadian advantage is an advantage gained when an organism's biological cycles are in tune with its surroundings. It is not a well studied phenomenon, but it is known to occur in certain types of cyanobacteria, whose endogenous cycles, or circadian rhythm, "resonates" or aligns with their environment. It is known to occur in plants also, suggesting that any organism which is able to attune its natural growth cycles with its environment will have a competitive advantage over those that do not. Circadian advantage may also refer to sporting teams gaining an advantage by acclimatizing to the time zone where a match is played. In organisms In the context of bacterial circadian rhythms, specifically in cyanobacteria, circadian advantage refers to the improved survival of strains of cyanobacteria whose endogenous cycles "resonate" or align with the environmental circadian rhythm. For example, consider a strain with a free-running period (FRP) of 24 hours that is co-cultured with a str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in plast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
