picocyanobacteria
{{Short description|Fraction of cyanobacteria between 0.2 and 2 μm}}
Picocyanobacteria are cyanobacteria that are part of the picoplankton, which is the fraction of plankton composed by cells between 0.2 and 2 μm.{{cite journal |vauthors=Trinh S, Haggoud A, Reysset G |title=Conjugal transfer of the 5-nitroimidazole resistance plasmid pIP417 from Bacteroides vulgatus BV-17: characterization and nucleotide sequence analysis of the mobilization region |journal=Journal of Bacteriology |volume=178 |issue=23 |pages=6671–6 |date=December 1996 |pmid=8955281 |doi=10.1128/jb.178.23.6671-6676.1996 |pmc=178560 }} Picocyanobacteria comprise the smallest photoautotrophs.{{cite journal |last1=Cabello-Yeves |first1=Pedro J. |last2=Callieri |first2=Cristiana |last3=Picazo |first3=Antonio |last4=Schallenberg |first4=Lena |last5=Huber |first5=Paula |last6=Roda-Garcia |first6=Juan J. |last7=Bartosiewicz |first7=Maciej |last8=Belykh |first8=Olga I. |last9=Tikhonova |first9=Irina V. |last10=Torcello-Requena |first10=Alberto |last11=De Prado |first11=Paula Martin |last12=Puxty |first12=Richard J. |last13=Millard |first13=Andrew D. |last14=Camacho |first14=Antonio |last15=Rodriguez-Valera |first15=Francisco |last16=Scanlan |first16=David J. |title=Elucidating the picocyanobacteria salinity divide through ecogenomics of new freshwater isolates |journal=BMC Biology |volume=20 |issue=1 |date=2022-08-08 |page=175 |issn=1741-7007 |pmid=35941649 |pmc=9361551 |doi=10.1186/s12915-022-01379-z |doi-access=free}}
