No, they claim that most of the filament is a single cell, albeit with compartmentalized DNA: > Strikingly, all techniques consistently showed that each filament was one continuous cell for nearly its entire length with no division septa, including the partial constrictions towards the apical pole. Only the most apical few buds were separated from the filament by a closed constriction and represented daughter cells "Apical" means the apex of the filament. In other words, toward the end of the filament the cell starts pinching off ("budding") to create daughter cells as part of its reproductive cycle. But the away from the end, the cell is contiguous. Fig. S2 is highly recommended.
