Blue—green algae (Cyanobacteria) are a special group of prokaryotes. They have chlorophyll and phycobiliprotein and can fix carbon by oxygen-evolution photosynthesis like plants; and their genome contains nucleotide sequences which are comparable with that of 16S and 5S rRNA of cubacteria. Therefore, in tradition, they …
Witryna24 gru 2024 · If there is no need for N 2 fixation, the production of proteins needed for fixation are tightly controlled. The nif genes are responsible for the coding of proteins related and associated with the fixation of atmospheric nitrogen into a form of nitrogen available to plants. These genes are found in nitrogen fixing bacteria and … http://www.perennialsolutions.org/insights-into-nitrogen-fixation-from-higher-order-taxonomy
