... "microspore embryogenesis" [refers] to the in vitro culture of the immature male gametophyte... The haploid embryos... can be germinated and grown into mature plants, but these plants are sterile due to their inability to produce gametes with a balanced chromosome number after meiosis. Chromosome doubling, which occurs either spontaneously in culture or after the application of... agents such as colchicine, restores the ploidy level and fertility of the derived plant...  3, fiche 1, Anglais, - microspore%20embryogenesis

Colchicine does not cure gout, but it will help prevent gout attacks. Colchicine is not an ordinary pain reliever and will not relieve most kinds of pain. Colchicine is also used to treat a rare condition called familial Mediterranean fever(FMF) in adults and children older than 4 years of age.  2, fiche 2, Anglais, - colchicine

Meadow-saffron is a perennial plant common in damp meadows of Europe, England, and Africa and cultivated in the U. S. and Canada... It produces several lilac or purple, crocus-like flowers in the fall... Meadow-saffron contains the poisonous alkaloid colchicine, which is used medicinally for gout and arthritis. The whole plant is poisonous, and small amounts of the bulb or seeds can cause death.  5, fiche 3, Anglais, - common%20autumn%2Dcrocus

Colchicine and its derivatives are used in the laboratory for cytologic studies to arrest cell division in mid-metaphase by disrupting the mitotic spindle fibers. Clinically, it is used to provide relief from acute attacks of gout and in conjunction with uricosuric agents(probenecid or sulfinpyrazone) and xanthine oxidase inhibitors(allopurinol) prophylactically to prevent acute attacks.  3, fiche 4, Anglais, - colchicine

Haploids have one set of chromosomes(n=1), which is the same as a gamete(pollen or egg cell). Haploids can be distinguished from diploids(n=2) by using gene markers which are closely linked with the gene under study so they can be visually detected by their physical characteristics. They are used in plant breeding to obtain pure lines that are homozygous by using colchicine to double the chromosome number, or by relying on spontaneous mutations.  1, fiche 6, Anglais, - haploid

Polyploidy can be induced with colchicine, an alkaloid of the meadow saffron(Colchicum autumnale) that inhibits mitosis... It hampers the development of the nuclear spindle. A mitosis that takes place after treatment with colchicin is called a C-mitosis. It enables an easier detection and identification of chromosomes than a normal mitosis does.  2, fiche 7, Anglais, - c%2Dmitosis
