The Influence of 0.03% Carbon Dioxide on Protein Metabolism of Etiolated Avena sativa Coleoptiles.

abstract：:During maturation and ripening of tomato (Lycopersicon esculentum, cv Tamar) fruits, there are differential changes in the steady state levels of chloroplast proteins. Western blot analysis indicated that with the exception of the core polypeptide of photosystem I (PSI) (subunit I) the whole complex disappears during ...
