Abstract
The changes in number, size, distribution and DNA content of plastid nucleoids in wild- and mutant-type leaves of an aurea variety of privet (Ligustrum ovalifolium. Hassk. var. aureum) were studied. Wild-type leaves did not show changes (in nucleoid number, size and distribution)! induced by different light intensities. Mutant leaves responded to changes in light conditions by changes in colour. During yellowing of regreened aurea leaves and bleaching of yellow aurea leaves the number of plastid nucleoids decreased with concomitant increase of their volume in such a fashion that the total volume of nucleoids and the DNA content per plastid remained constant. No degradation of chlo- roplast DNA before and during yellowing and bleaching of the aurea leaves was observed.
