Protoplast cultures are remarkable examples of plant cell dedifferentiation. The state of dedifferentiation is evidenced by changes in cell morphology, genome organization, as well as by the capability of protoplasts to differentiate into multiple types of cells (depending on the type of the stimulus applied). The first change in the genome structure is(More)
The present study investigated changes in the production of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in isolated mesophyll protoplasts and cell cultures of the cucumber Cucumis sativus cv. Marketer. Although only a minor increase in the level of nitrogen oxide (NO) was observed during the first 7 days of culture following protoplast(More)
Plants are increasingly exposed to heavy metal pollution in the environment. Cadmium (Cd), a non-essential metal, is known to exert strong phytotoxic effects. The aim of the present study was to examine the role of nitric oxide (NO), reactive nitrogen (RNS) and reactive oxygen (ROS) species in the responses of cucumber (Cucumis sativus) cell culture to high(More)
