title: Engineering C4 photosynthetic regulatory networks.
abstract: C4 photosynthesis is a complex metabolic pathway responsible for carbon fixation in major feed, food and bioenergy crops. Although many enzymes driving this pathway have been identified, regulatory mechanisms underlying this system remain elusive. C4 photosynthesis contributes to photosynthetic efficiency in major bioenergy crops such as sugarcane, Miscanthus, switchgrass, maize and sorghum, and international efforts are underway to engineer C4 photosynthesis into C3 crops. A fundamental understanding of the C4 network is thus needed. New experimental and informatics methods can facilitate the accumulation and analysis of high-throughput data to define components of the C4 system. The use of new model plants, closely related to C4 crops, will also contribute to our understanding of the mechanisms that regulate this complex and important pathway.
