In the present study we tested the allelopathic activity of the picocyanobacterium Synechococcus sp. against the following coexisting unicellular eukaryote microalgae: Porphyridium purpureum, Stichococcus bacillaris, Prymnesium parvum and Nitzschia dissipata. With these species, we covered a wide range of taxonomic groups. We demonstrated that both the addition of Synechococcus sp. cell-free filtrate and coculture inhibited the growth, chlorophyll content and photosynthetic rate of P. purpureum and S. bacillaris. Conversely, P. parvum, a well-known mixotroph, was positively affected by both Synechococcus sp. treatments. In contrast, N. dissipata was not affected by either the picocyanobacterial filtrate or coculture. These results suggest that the negative allelopathic effect is related to a reduction in the photosynthetic rate, and that Synechococcus sp. allelopathy should be taken into account in the interactions between picocyanobacteria and eukaryote competitors coexisting in a planktonic system.<\/jats:p>","DOI":"10.1071\/mf18024","type":"journal-article","created":{"date-parts":[[2018,8,22]],"date-time":"2018-08-22T03:29:14Z","timestamp":1534908554000},"page":"1472-1479","source":"Crossref","is-referenced-by-count":24,"title":["Allelopathic activity of the picocyanobacterium Synechococcus sp. on unicellular eukaryote planktonic microalgae"],"prefix":"10.1071","volume":"69","author":[{"given":"Sylwia","family":"Sliwinska-Wilczewska","sequence":"first","affiliation":[{"name":"ADivision of Marine Ecosystems Functioning, Institute of Oceanography, University of Gdansk, Avenue Pilsudskiego 46, P-81-378 Gdynia, Poland."}]},{"given":"Aldo Barreiro","family":"Felpeto","sequence":"additional","affiliation":[{"name":"BInterdisciplinary Center of Marine and Environmental Research\u2013Centro Interdisciplinar de Investiga\u00e7\u00e3o Marinha e Ambiental (CIMAR\/CIIMAR), University of Porto, Avenida General Norton de Matos s\/n, PT-4450-208 Matosinhos, Portugal."},{"name":"DCorresponding author.
