How can you use “cyanobacteria” in a sentence? Here are some example sentences to help you improve your vocabulary:
The earliest biomarker evidence of eukaryotes is at 2.7 Ga [ 11 ] and the earliest fossils appear 2.1 Ga [ 12 ] . The fossil record of cyanobacteria has been argued to extend to 3.5 Ga [ 13 ] but the biomarker evidence at 2.7-2.
Nevertheless, an evolutionary affinity between Cyanobacteria ( Synechocystis ) and Actinomycetes ( Mycobacterium ) appears plausible, particularly given the presence, in these bacterial groups, of well-developed and partly similar signal transduction systems [ 27 ] . The connection between two hyperthermophilic bacteria, Aquifex and Thermotoga, also has obvious biological meaning, although, in this case, particular caution is due, given the possibility of preferential horizontal gene exchange between these organisms that inhabit similar environments.
Another recent study addressed the issue of a global tree through phylogenetic analysis of 14 concatenated sets of orthologous proteins, for which no strong evidence of horizontal transfer was available [ 33 ] . Notably, some of the unexpected groupings within the bacterial domain reported in this study coincide or overlap with those described here, namely, a spirochete-chlamydial clade and a Deinococcales-Cyanobacteria clade.
In the case of the cyanobacteria, it is possible that some of the PRC-H-like proteins that contain an equivalent acidic residue might associate with their very distinct photosynthetic reaction centers [ 29, 30, 31], by analogy with their purple bacterial counterparts.
Moreover, the appearance of cyanobacteria immediately prior to the earliest undisputed evidence for the presence of oxygen (2.
