摘要: The photosynthetic apparatus of plant chloroplasts contains two photosystems, termed Photosystem I (PSI) and II (PSII). Both PSI PSII contain several types chlorophyll a/b-binding (CAB) polypeptides, at least some which are structurally related. It has been previously shown that multiple genes encoding one type CAB polypeptides exist in the genome many higher plants. In tomato, there eight such genes, distributed three independent loci. Genes a second have isolated from species, but precise location gene products not determined. Here we show tomato unlinked this polypeptide is also localized PSII.
