Notes:
For development of flagella by myxamoebae of the true slime mold, Didymium nigripes, optimal results were obtained when they were incubated in 0.05 M NaHCOa (pH 9.1). Streptomycin inhibited flagella formation in pH 6.2 phosphate buffer but had no effect in NaHC03. The time necessary for 50% of the population of myxamoebae to become flagellated was independent of the concentration of myxamoebae; hence, the morphogenesis probably follows first-order kinetics. The acquisition of flagella was divisible into 4 stages by means of time-lapse cinephotomicroscopy: an ameboid stage, a stage of morphogenesis, an ameboid-flagellate stage, and a free-swimming flagellate stage. At least 90% of the population developed flagella within 60 min. under optimal conditions. The flagellar apparatus consists of a long and a short flagellum, each arising from a granule in the blepharo-plast. The blepharoplast is connected to the nucleus by a rhizoplast.
