For those working and interested in the field of chloroplast ribosomes, an ideal overview is provided by this text. Topics covered include: Plastid rRNAs and tRNAs; Structure, Organization and Expression of Their Genes; Plastid Ribosomal Proteins and Their Genes in Higher Plants; Plastid Ribosomes and Factors of Algae and of Cyanelles; Functional Aspects; Physiological Aspects. Stressed is the fact that biosynthesis and function of the translational apparatus relies upon two separate genetic systems and thus produce particular regulatory problems with fundamental significance. The...
