pubmed:abstractText |
We have isolated a cDNA (PAP) corresponding to a single nuclear gene that encodes an approximately 30-kD major protein of bell pepper (Capsicum annuum L.) fruit chromoplasts. RNA and protein analyses revealed that, although at a low level, this gene is also expressed in every organ of the plant, the amount of the corresponding transcript and protein dramatically increasing in the latter stages of fruit development. Western-blot and immunocytochemical analyses of purified chloroplasts from leaves and fruits and of chromoplasts from red fruits showed that the encoded protein is the major component of plastoglobules and fibrils and is localized on the outer surface of these lipid structures. Analyses of PAP in plants belonging to different taxa revealed that it is expressed and highly conserved in both monocotyledonous and dicotyledonous plants. The presence of the protein in plastids not differentiating into chromoplasts indicates that PAP is expressed irrespective of the ontogeny of various plastid lines. In light of our results and since the encoded protein, identical to that previously named ChrB or fibrillin, is present in plastoglobules from several species and accumulates in the fibrils of bell pepper chromoplast, we propose to designate it as a plastid-lipid-associated protein.
