Abstract

Plastid DNA (ptDNA) in albino rice plants regenerated from pollen by anther culture was investigated by Southern blotting. Of the 20 albino plants investigated, 7 contained ptDNA that had suffered large-scale deletion. The size and location of the deletions differed among the plants. In all cases about 30 kbp of the region containing the PstI-2 fragment (15.7 kbp) had been retained. The deleted ptDNA molecules were retained in calluses derived from the roots of each albino plant.
