The new flagellum is attached to the mature flagellum via a flagella connector structure. a Low magnification of a trypomastigote cell in the PV. b–d TEM consecutive 80 nm-thick serial sections of the flagellar pocket region. e Image colorized highlighting different structures. a A trypomastigote cell with the kinetoplast in a posterior location in relation to the nucleus. b The new flagellum shares the flagellar pocket with the mature flagellum. c, d The short new flagellum is laterally attached to the mature flagellum via a flagella connector structure (bordeaux arrowheads). The flagella connector is an electron-dense plate structure organized into three distinct layers laterally connecting the distal region of the new flagellum to the mature flagellum. e Basal bodies are colorized in dark grey, transition zones in magenta and axonemes in green. Abbreviations: BB, basal body; TZ, transition zone; Axo, axoneme. Number 1 refers to the mature flagellum and number 2 to the new flagellum. Scale-bars: a 1 µm; b–e 500 nm
