Planktothrix rubescens strain PCC 7821

Planktothrix rubescens strain PCC 7821 is a cyanobacterium primarily found in various prealpine lakes, including Lake Bourget and Lake Constance. This organism is characterized by having a single replicon, which contributes to its genomic stability and adaptability within its aquatic habitat. The strain is indexed under the accession number CZCZ00000000.2, allowing for its genetic and functional analysis within the scientific community. Planktothrix rubescens is noted for its ability to thrive in freshwater environments, often contributing to the biomass in these ecosystems. Ecologically, Planktothrix rubescens plays a significant role in nutrient cycling and primary production within its habitats. Its presence can influence the overall productivity of the aquatic ecosystem, as it is capable of photosynthesis and can fix nitrogen. This capability allows it to contribute to the nutrient dynamics, especially in nutrient-limited conditions, potentially affecting the growth of other aquatic organisms. Understanding the specific traits and ecological roles of Planktothrix rubescens strain PCC 7821 enhances our knowledge of the biodiversity and functional dynamics in freshwater ecosystems, highlighting the importance of cyanobacteria in maintaining ecological balance and supporting aquatic life.
