e0“These two types of mesophyll cell have a strongly similar ontogeny, distinguished mainly by the collapse of the fusoid cells in Poaceae, which is not observed in the colourless cells in J. ascendens”

Other claims from this paper (7)
- Observation An apparent mature fusoid cell is typically a cavity left after collapse of the initial cell and derivatives.
- Observation Each cavity is delimited by collapsed fusoid cells perpendicular to veins.
- Observation Fusoid cells in studied Poaceae originate from ground meristem.
- Observation Colourless cells in Joinvillea ascendens originate from ground meristem.
- Observation Fusoid cells share meristematic origin across early and later Poaceae lineages and are homologous.
- Observation Poaceae fusoid cells and Joinvilleaceae colourless cells are suggested to be homologous.
- Mechanism Fusoid cells in young grass leaves may synthesize and store starch granules.
