In addition to the universal pathways of glycolysis and gluconeogenesis, plants have the unique reaction sequences for CO2 reduction to triose phosphates by photosynthesis and the associated reductive pentose phosphate pathway. These reactions must be coordinately regulated to avoid wasteful futile cycling and to ensure proper allocation of carbon to energy production and synthesis of starch and sucrose. Plant productivity is determined by the interaction between these complex series of carbohydrate metabolisms at biochemical and molecular level. Research in the area of carbon portioning, transport, and source-sink interactions are underway to understand chloroplast metabolism, carbohydrate synthesis, carbohydrate transport pathways, and carbohydrate storage and catabolism. This research will not only provide valuable information on these metabolisms but also on how to manipulate plants to improve yield. Additionally, circadian clock and different types of stress are also important determinants of the pace of carbohydrate metabolism in plants. “Omics” technologies suggest that genes that participate in carbohydrate metabolisms are differentially regulated depending on time and stress conditions.

In the present Research Topic, we will focus on the current status of studies performed worldwide to understand carbohydrate metabolism and its regulation in photosynthetic organisms which will provide valuable information for the manipulation of plants for better yield. In particular, this Research Topic will collect up-to-date carbohydrate metabolism studies of plants addressing questions focused on the following aspects:

• Starch and sucrose metabolism
• Trehalose and other sugar metabolisms
• Regulation of carbon partitioning
• Modeling studies of plant carbohydrate metabolism
• Metabolomics studies related to carbohydrate metabolism in unicellular or plants
• Relationship between the circadian clock and carbohydrate metabolism
• Regulation of carbohydrate metabolism under different stress conditions

This Research Topic will collect Reviews, Mini-Reviews, Methods, and Original Research Articles to give an overview of the different aspect of carbohydrate metabolism. Spontaneous submissions will not be considered.


Keywords: Starch and Sucrose Metabolism, Photosynthesis, Plant Yield, Circadian Clock, Carbon Partitioning
