Název v původním jazyce

The heterochromatin as a marker for protoplast differentiation of Cucumis sativus

Popis výsledku v původním jazyce

The protoplast cultures of Cucumis sativus in two culture systems were used to study heterochromatin reassembly during dedifferentiation of isolated protoplasts and their subsequent differentiation into calli and proembryos. Here we show that dedifferantiation of the cucumber mesophyll cells is accompanied by a dramatic reduction in size and numbers of nuclear chromocenters. Although chromocenters were newly established during protoplast culture, the measured relative heterochromatin content differed according to the culture system used. Protoplast culture leading to proembryo formation displayed a lower level of relative heterochromatin content than cultures resulting in calli and the relative heterochromatin content reached values close to those estimated for somatic embryos.
