A comparative study of the potentiating effect of caffeine and poly-d-lysine on chromosome damage induced by X-rays in plant cells

Human and Plant Proliferating‐Cell Nuclear Antigen have a Highly Conserved Binding Site for the p53–Inducible Gene Product p21WAF1

“…When plants are exposed to ultraviolet or ionising radiation, a broad spectrum of physical and chemical modifications of their DNA occur, which eventually leads to arrest of cell division (Mateos et al, 1992;Chagvardieff et al, 1989;Inoue and van Huystee, 1984). Studies have shown that plants possess mechanisms for repair of damaged DNA which include photoreactivation, excision repair (McLennan, 1988) and recombinational repair (Cerutti et al, 1992).…”
