dig-icm-es-10261-1512892020-12-10T07:38:52Z Phenotypic plasticity in freshwater picocyanobacteria Huber, Paula Acinas, Silvia G. Gasol, Josep M. Unrein, Fernando Consejo Nacional de Investigaciones Científicas y Técnicas (Argentina) Agencia Nacional de Promoción Científica y Tecnológica (Argentina) Huber, Paula ... et al.-- Thematic Issue on Environmental Glycerol Metabolism.-- 14 pages, 8 figures, 1 table, supporting information https://dx.doi.org/10.1111/1462-2920.13638 Picocyanobacteria can occur as single-cell (Pcy) or as colonies (CPcy). Published evidence suggests that some Pcy strains have the capability to aggregate under certain culture conditions, however this has not been demonstrated to occur in natural environments. We investigated whether the Pcy and CPcy belong to the same species (i.e. phylotype), and the factors that determine their morphological and genetic variability in a hypertrophic shallow lake dominated by picocyanobacteria. Six main different morphologies and >30 phylotypes were observed. All sequences retrieved belonged to the ‘Anathece + Cyanobium’ clade (Synechococcales) that are known to have the capability of aggregation/disaggregation. The temporal variation of picocyanobacteria morphotype composition was weakly correlated with the DGGE temporal pattern, and could be explained by the composition of the zooplankton assemblage. Laboratory experiments confirmed that the small cladoceran Bosmina favoured the dominance of CPcy, i.e. Cyanodictyon doubled the size of the colonies when present, most likely through the aggregation of single-cell picocyanobacteria into colonies. Flow cytometry cell sorting and 16S rRNA + ITS sequencing of the Pcy and CPcy cytometrically-defined populations revealed that some phylotypes could be found in both sorted populations, suggesting phenotypic plasticity in which various Synechococcales phylotypes could be found in situ either as single-cells or as colonies This study was supported by the Argentinean Network for the Assessment and Monitoring of Pampean shallow-lakes (PAMPA2–CONICET), 3PA and the ANPCyT (PICT-2011-1029 and PICT-2014-1290) Peer Reviewed 2017-06-13T06:57:32Z 2017-06-13T06:57:32Z 2017-03 2017-06-13T06:57:32Z artículo http://purl.org/coar/resource_type/c_6501 doi: 10.1111/1462-2920.13638 issn: 1462-2912 e-issn: 1462-2920 Environmental Microbiology 19(3): 1120-1133 (2017) http://hdl.handle.net/10261/151289 10.1111/1462-2920.13638 http://dx.doi.org/10.13039/501100002923 http://dx.doi.org/10.13039/501100003074 https://dx.doi.org/10.1111/1462-2920.13638 Sí none Society for Applied Microbiology |
