ADDITIONAL INDEX WORDS. carbon assimilation, immunoblotting, differential expression ABSTRACT. Levels of the large subunit (LSU) of rubisco (ribulose 1,5 bisphosphate carboxylase/oxygenase) were measured in vegetative and floral organs of 'Violet' Japanese morning glory ( Ipomoea ( Pharbitis) nil Roth). Identification of the LSU in polypeptides separated by two-dimensional gel electrophoresis allowed estimation of the relative abundance of this polypeptide in the organs examined. Further quantitation was achieved by immunoblotting protein extracts either alone or in combination with various amounts of extracts from other organs. The amount of LSU decreased in the order leaves > cotyledons > sepals > corollas > androecium, gynoecium. The relative abundance of LSU in sepals (74%) compared to photosynthetically competent organs (leaves (100%) and cotyledons (81%)) suggests that sepals may be photosyntheti- cally competent in supporting development of the other floral organs. In higher plants carbon is partitioned from organs that fix CO 2 or store long-term carbohydrate reserves (source organs) to those organs or plant parts that require imported carbon for growth and maintenance (sink organs). Virtually all organs act as sinks at some time or another during their development. For example, roots and young leaves of tomato were shown to compete more effectively for assimilates than flowers; however, when tomatoes began to fruit, the fruit were stronger sinks than either roots or young leaves (Bravdo et al., 1977; Ho, 1984). The competitiveness of a particu- lar organ or tissue as a sink is related to the number of cells in the organ and its physiological state, and is therefore a consequence of both genetic determination and environmental influences (Ho, 1988).
