Plastid Development in Pisum sativum Leaves during Greening : I. A Comparison of Plastid Polypeptide Composition and in Organello Translation Characteristics.
Changes in plastid polypeptide composition during greening of etiolated peas were investigated by two-dimensional gel electrophoresis. One hundred of the more than 250 polypeptides which could be detected upon silver staining were followed during plastid development. Thirty-nine polypeptides decreased in abundance on a per organelle basis. Twentythree of the 46 polypeptides which increased in a...
متن کاملLipid biosynthesis by isolated plastids from greening pea, Pisum sativum.
Isolated etioplasts from 8-day-old dark-grown pea seedlings incorporated [1-(14)C]acetate into lipid at a relatively low rate. Plastids from seedlings that had been illuminated for at least 2 hr showed an enhanced incorporation provided the plastids were illuminated during incubation with the labeled acetate. Dark incubation or the addition of 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU) decr...
متن کاملChanges in Leaf Proteins of Peas, Pisum sativum L., during Development on Deflorated Plants.
The soluble (sap) proteins of leaves of pea, Pisum sativum L. cvs. Alaska and Greenfeast, allowed to develop normally or deflowered, to prevent senescence, were separated by isoelectric focusing.There was a decline in certain proteins, with increases in others as the leaves aged but preventing senescence of the whole plant did not alter the pattern of change in leaf proteins. We concluded that ...
متن کاملControl of storage-protein synthesis during seed development in pea (Pisum sativum L.).
The tissue-specific syntheses of seed storage proteins in the cotyledons of developing pea (Pisum sativum L.) seeds have been demonstrated by estimates of their qualitative and quantitative accumulation by sodium dodecyl sulphate/polyacrylamide-gel electrophoresis and rocket immunoelectrophoresis respectively. Vicilin-fraction proteins initially accumulated faster than legumin, but whereas legu...
متن کاملGlycoprotein Metabolism in the Cotyledons of Pisum sativum during Development and Germination.
The glycoprotein nature of legumin and vicilin, the reserve globulins in the cotyledons of Pisum sativum was studied. Legumin from mature seed was found to contain 1% neutral sugars (mannose and glucose) and 0.1% amino sugar (glucosamine), whereas vicilin contained 0.3% neutral sugar (mannose) and 0.2% amino sugar (glucosamine). On the basis of the incorporation of (14)C-labeled glucosamine, it...
