Cytogenetic and epigenetic alterations by cobalt and nickel on Zea mays L
Özet
Changes in DNA methylation in Zea mays plantlets in response to cobalt and nickel (5, 10, 20, and 40mmol L-1) evaluated by the coupled restriction enzyme digestion-random amplification technique revealed dose-related increases in hypermethylation. The effects on mitotic index and phytohormone levels were also determined. Co and Ni caused a decrease in mitotic index and an attenuation in the growth-promoting hormones gibberellic acid, zeatin, and indole acetic acid, while abscisic acid levels rose. These findings have shown that the increase in abscisic acid levels and DNA methylation depend on the concentrations of Co and Ni.
