The "chromosome" gene allows cyanobacteria to adapt to different environments

an international team of researchers has recently discovered that cyanobacteria, the cornerstone of marine ecosystems, have a "color-changing dragon" characteristic that regulates pigmentation in the body according to the light in the environment and uses sunlight energy better.
cyanobacteria are not algae, but a class of single-celled primary nuclear organisms, also known as blue bacteria, that can be photochemically used. Cyanobacteria is one of the oldest and most widely distributed organisms on Earth and the first link in the marine food chain.
cyanobacteria have a variety of pigments involved in photocodychrome. To study the relationship between pigment types and geographical distribution, researchers at the University of Warwick in the UNITED Kingdom analyzed cyanobacteria samples from various seas around the world in detail. The samples belonged to a representative group of cyanobacteria, polycyclium, collected by the Tara Marine Science Team of France.
analysis shows that the adaptation of environmental lighting conditions is the main factor affecting the distribution of poly-splor algal pigment types, which is achieved by a number of "color changer" genes. In open areas with plenty of blue light, the pigmentation that is suitable for absorbing blue light is particularly abundant, in warm equatorial waters and coastal areas, pigment types are suitable for absorbing green light that dominates the environment, and in red estuaries where light is red, pigment types are more suitable for red light.
papers are published in the
States. The researchers say the results deepen understanding of the biological mechanisms of cyanobacteria and help predict the impact of climate change on marine ecosystems. (Source: Xinhua News Agency)
