Growth and development of cultured carrot cells and embryos under spaceflight conditions.
Morphogenetically competent proembryonic cells and well-developed somatic embryos of carrot at two levels of organization were exposed for 18.5 days to a hypogravity environment aboard the Soviet Biosatellite Cosmos 1129.  It was confirmed that cultured totipotent cells of carrot can give rise to embryos with well-developed roots and minimally developed shoots.  It was also shown that the space hypogravity environment could support the further growth of already-organized, later somatic embryonic stages and give rise to fully developed embryo-plantlets with roots and shoots.
