Cytogenetic damage induced by magnesium in wheat root meristems

Cytogenetic damage induced by magnesium in wheat root meristems

ike other metals, magnesium can be genotoxic for plants by generation of oxygen free radicals. This metal can induce mitotic alterations chromosome breaks, achromatic lesions, chromosome aggregations, lagging chromosomes, micronuclei. Mitotic spindle modifications leading to poliploidy and aneuploi...
