Growth and Development of Carrot Cells and Embryos in Space (COS 1129-10)
Principal Investigator
Research Area:
Plant biology
Species Studied
Scientific Name: Daucus carota Species: Carrot


A major area of research in space biology has been to ascertain whether plant development can proceed normally and consecutively in the weightless state, especially the salient feature in which a cell gives rise to a multicellular unit and thence to an embryo with shoot and root growing regions. In this study, morphogenetically competent pro-embryonic cells and well developed somatic embryos of carrot at two levels of organization were exposed for 19.5 days to a hypogravity environment.
