Fig. 1From: Plasticity first: molecular signatures of a complex morphological trait in filamentous cyanobacteriaPhenotypic plasticity of colony morphology in Fischerella. Growth stages of Fischerella muscicola PCC 7414 (a), and Fischerella thermalis PCC 7521 (b). When grown in BG11o, Fischerella species show the true-branching phenotype (left panel), whereas the culture under 10 mM sucrose resulted in non-branched filaments (right panel). Hormogonia are marked with white arrows. All cultures were grown at 37 °C and a light intensity of 30 μmol/m2 s1 Back to article page
