“…Sobkowiak and Deckert (2003) have shown that an exposure of soybean to Cd impairs cell division by causing earlier cell entry into the S phase and by decreasing the rate of DNA synthesis. Leaf development is driven by 2 fundamental growth processes: cell division and cell expansion.…”

IntroductionCadmium (Cd) is a highly toxic trace element, which enters the environment mainly from industrial processes and phosphate fertilisers. It can reach high levels in agricultural soils and is easily assimilated by plants. When taken up in excess by plants, Cd induces various visible symptoms of phytotoxicity, e.g., leaf roll, chlorosis and necrosis, growth retardation, browning of root tips, and finally death (

“…Micronuclei and c-mitosis cells have also been recorded (Liu et al 2003/4). The aberrations could be the effect of Cd on DNA and RNA synthesis (Christie andCosta 1984, Sobkowiak andDeckert 2003). This explains the strong inhibition of mitosis in root tips after prolonged Cd treatments at a high concentration (Liu et al 2003/4).…”

We have investigated the effects of cadmium on the microtubular (MT) cytoskeleton in the root tip cells of Allium sativum L. using indirect immunofluorescence microscopy. Cd affected the mechanisms controlling the organization of MT cytoskeleton, as well as tubulin assembly/disassembly processes. Cd induced the formation of abnormal MT arrays, consisting of discontinuous wavy MTs or short MT fragments at the cell periphery. Cadmium caused irregular nuclear disorder in cells where the MT organization and function was disturbed. Furthermore, with increased Cd concentration and duration of treatment the MTs depolymerized more severely, the frequency of abnormal cell increased and the mitotic index decreased progressively. The above findings showed that MT cytoskeleton is one of target sites of Cd toxicity in root tip cells.

“…It is highly reactive and inactivates various enzymatic processes. Many studies indicated inhibition of plant growth (Maksymiec and Baszyński 1996, Maksymiec 1997, Sobkowiak and Dekert 2003, Guo et al 2007, Sabreen and Sugiyama 2008. The exact mechanism of cadmium-induced growth inhibition is still unclear.…”

“…Cd-induced root growth inhibition can be a consequence of Cd-stimulated premature xylogenesis and shortening of the root elongation zone (Ďurčeková et al 2007). Indirect effects of Cd on plant growth include microtubule alteration (Xu et al 2009), depressed K, Fe, Mg or Ca accumulation, inhibition of photosynthesis (Greger and Bertel 1992, Trivedi and Erdei 1992, Moya et al 1993, Skórzyńska and Baszyński 1998, Sandalio et al 2001 or reduction in the cyclin B1 and cyclin D content (Cockcroft et al 2000, Sobkowiak andDekert 2003). However, these effects were usually observed after a few days of treatment with the heavy metal and did not indicate any preliminary changes induced within cells.…”

“…This signalling factor can inhibit growth of various plant tissues (Maciejewska and Kopcewicz 2003) through depression of elongation or cell cycle processes (Irving et al 1999, Saniewski et al 1987, Świątek et al 2002, Merkouropoulos and Shirsat 2003. This indicates that Cd can influence plant growth indirectly through induction of the jasmonate signalling pathway.…”

Short-time direct and indirect effects of 25 µM Cd on the growth of dicotyledon (Phaseolus coccineus) and monocotyledon (Allium cepa) plants were investigated in the presence of inhibitors of ethylene synthesis, NADPH oxidase, and the octadecanoid pathway. Only 5 min-long action of Cd was enough for inhibition of growth in bean roots, but its recovery time was extended to several days. After 7 h treatment, Cd was significantly accumulated in bean roots, but maximum H 2 O 2 accumulation was seen after 1 h. Cd-induced H 2 O 2 accumulation decreased especially after addition of ethylene inhibitor silver thiosulphate (STS). Low Cd accumulation and high growth inhibition were observed also in bean leaves and in A. cepa roots. The inhibitors of the octadecanoid pathway greatly weakened the inhibitory effect of Cd in P. coccineus roots, while no significant effect was observed in A. cepa. NADPH oxidase and ethylene blockade reversed (in the case of bean plants and indirectly treated A. cepa plants) or significantly diminished Cd action. Cd-induced growth inhibition of P. coccineus leaves was also alleviated by most inhibitors of the jasmonate pathway and by STS. These results indicate that Cd may have indirect and direct effects on growth processes.
