“…11, 22). Therefore, for all these irregularities in the chromosome, sticky chromosomes might be used as a measurement of the cytotoxicity of the herbicides which ultimately might lead to cell death [36,37]. A number of her bicides are known for artificial induction of sticky chromosomes [38,39].…”

The widespread use of the herbicides for weed control and crop productivity in modern agriculture exert a threat on eco nomically important crops by way of cytological damage to the cells of the crop plant or side effects, if any, induced by the herbicides. In the present communication, author describes the effects of 2,4 D and Isoproturon on chromosomal mor phology in mitotic cells of Triticum aestivum L. The wheat seedlings were treated with range of concentrations (50-1200 ppm) of 2,4 D and Isoproturon for 72 h at room temperature. In the mitotic cells, twelve distinct chromosome structure abnormalities were observed over control. The observed irregularities were stickiness, c mitosis, multipolar chromosomes with or without spindles, fragments and bridges, lagging chromosomes, unequal distribution of chromosomes, over contracted chromosomes, unoriented chromosomes, star shaped arrangement of the chromosomes, increased cell size and failure of cell plate formation. The abnormalities like stickiness, fragments, bridges, lagging or dysjunction, unequal distribution and over contracted chromosomes meet frequently.

To clarify the mechanism of isopropyl-N-phenyl carbamate (IPC) action on higher plant cells the sensitivity of microtubules (cortical network and mitotic arrays) and microtubule organizing centers to IPC treatment (30 microM) in IPC-resistant and sensitive Nicotiana sylvestris lines was studied. It was clearly demonstrated that IPC does not depolymerize plant MTs but causes the MTOC damage in cells, which results in MTOC fragmentation, splitting of the spindle poles and in abnormal division spindle formation. It was also found that IPC-resistance of mutant N. sylvestris line correlates not with tubulin resistance to IPC action but possibly with resistance of one of the proteins involved in MTOC composition.
