Ontogeny of fusoid cells in Guadua species (Poaceae, Bambusoideae, Bambuseae): Evidence for transdifferentiation and possible functions

Fusoid cells have been interpreted as cells or intercellular spaces, according to different authors. Here, structural and ultrastructural evidence is provided relative to the origin and changes experimented by chlorenchyma cells ("arm cells") to differentiate into fusoid cells with large i...
