Chemically induced chromosome damage in early-developing embryos of Anilocra physodes L following exposure to bis chloroprotoporphyrin IX


, : Chemically induced chromosome damage in early-developing embryos of Anilocra physodes L following exposure to bis chloroprotoporphyrin IX. Applied Organometallic Chemistry 7(5): 295-301

In order to obtain chromosome preparations from early-developing embryos of Anilocra physodes, a squash technique has been successfully employed. Results gathered after exposure of this material to bis(dimethyltin(IV)chloro)protoporphyrin IX (((CH-3)-2SnCl)-2 cntdot Protoporphyrin IX) solutions at different exposure times suggest that this chemical complex is capable of producing abnormal metaphase and anaphase figures in proportion to its concentration and not to exposure length. Essentially, all of the chromosome abnormalities are classifiable as chromosome fragments mainly observed at the metaphase stage; chromosome bridges; and large decondensed chromosome regions.
