Abstract
Progress occurred during the last decade with regard to understanding carbohydrate metabolism and assimilate partitioning in the Graminaceous plants, wheat (Triticum aestivum L.), barley (Hordeum vulgare L.) and rice (Oryza sativa L.). The concept that metabolic pathways are regulated at specific enzyme steps was confmned by research perfonned during this period. The central importance of fructose 2,6-bisphosphate and inorganic pyrophosphate in controlling carbon fluxes in plant cells was assessed and the key role of sucrose-phosphate synthase in regulating sucrose metabolism was clearly demonstrated. It is now feasible to discuss some of the biochemical factors involved in source/sink interactions. High resolution chromatographic procedures and analytical improvements made it possible to separate and detect carbohydrates with tremendous sensitivity. Several enzymes in the leaf starch and fructan pathways have been isolated and characterized and these research areas can be expected to grow rapidly in the future. Assimilate partitioning benefited from the explosive growth in molecular biology primarily in the fields of plant development and environmental stress.
