Literature data and results of the studies carried out us concerning the involvement of plant cell cytoskeleton in cellular mechanisms of metal toxicity are summarized. Characteristics of cytotoxic effect of metals on plant cytoskeleton and, in particular, on microtubules and actin filaments are reviewed. Particular attention is paid to cellular and molecular mechanisms of metal impact on cytoskeleton...
The effects of an exogeneous NO donor, sodium nitroprusside, on the orientation and organization of cortical microtubules in Arabidopsis thaliana root cells expressing GFP-MAP4 were studied in vivo. It was found that sodium nitroprusside treatment (10–500 μM, 24 h) caused the acceleration of primary root growth and enhanced initiation of root hairs in the differentiation zone. The influence of sodium...
