(Prymnesiophyceae) from Valparaíso Bay Orietta Beltrami Marcela Escobar Gloria Collantes Ciencias de la Tierra HPLC Chile culture patelliferum fine structure An unidentified flagellate with a short non coiling haptonema was found by chance in a living phytoplanktonsample taken from Valparaíso Bay, Chile. Monocultures were obtained and kept in Provasoli medium (PES),at salinity 34.0, 16 ± 2ºC, 40 µmol photon·m-2·s-1, and 11:13 h light:darkness. The strain (MLB298) was obtained bythe capillary method. Cells were harvested by centrifugation, and pigments were extracted and examined using HPLC.Cells were examined with both light and electron microscopy. The genus was identified as Prymnesium Conrad, due toits characteristic pigments (Chl c3 plus fucoxanthin) and cellular features, mainly haptonema and scale characteristics.Further cultured studies of the cells revealed asexual and sexual reproduction. Electron microscopy observations of thescales showed the radial pattern of P. patellifera and the concentrical fibrilar pattern of P. parvum, confirming that P.patellifera and P. parvum are alternating generations of the same species (conspecifity). P. parvum f. patelliferum (Green,Hibberd & Piennar) Larsen stat. nov. is cited herein for the first time for the Chilean coast. 2007 artículo científico 0716-1069 https://www.redalyc.org/articulo.oa?id=45635109 en http://www.redalyc.org/revista.oa?id=456 Investigaciones Marinas application/pdf Pontificia Universidad Católica de Valparaíso Investigaciones Marinas (Chile) Num.1 Vol.35 |
