etioplasts do not synthesize a limited set of chloroplast-encoded polypeptides which are major constituents of chloroplast thylakoid membranes : two chlorophyll apoproteins of photosystem i ( 68 and 65 kda ) , two chlorophyll apoproteins of photosystem ii ( 47 and 43 kda ) , and a 32-kda polypeptide which has now been identified as the psba gene product .
