Plastid Development and Ultrastructure in Yellowish Mutants of Sugar Cane

Abstract: The comparisons of the ultrastructures of plastids in yellowish mutant and yellowish-green striped mutant and in normal green plant from tissue culture of sugar cane were made. There was no difference found in the structure and development of chloroplasts between the normal green leaves and the green tissue of striped leaves, but the plastid in the yellowish tissue of two kinds of mutants were anomalous. They had not a fully developed system of grana and stroma lameilae as in the normal green leaves. This aberrant plastid contained only some vesicles, a few lamellae and more or less clearly defined ribosome particles and DNA-like mierofibrils, while some stacking and swelling of thylakoids were often observed. In some sections of this aberrant plastid a bunchy lamellae and cross connective fibrils between parallel lamellae were often found too. However, the mixed cell which contains both of normal chloroplast and defective plastid together was never found in the leaves of the mutant plants. It was suggested that yellowish and yellowish-green striped leaves from tissue culture of sugar cane might be caused by nuclear gene mutation.
