Improving C4 photosynthetic chilling tolerance in bioenergy crops: the search for elite breeding materials
… due to photosynthetic limitations at chilling temperatures (<20° C). The mechanistic limitation at chilling temperatures has been suggested to be caused by the chilling-induced lability of pyruvate phosphate dikinase (PPDK) and decrease in ribulose-1,5-bisphosphate …

Understanding the physiological and molecular basis of chilling tolerance across species of the C4 genera Miscanthus and Spartina
… giganteus has been found to possess significant chilling tolerance relative to other C4 species. This dissertation aims to understand this apparently unique tolerance of C4 photosynthesis with three investigations (Chapters 2-4). Chapter 2 analyses the transcriptome of M. × giganteus on …

Exploiting the Productivity of C4 Photosynthesis in Cool Temperate Climates: Mechanisms and Thresholds of Cold Tolerance in Miscanthus, Saccharum, and Spartina pectinata
… season and produce leaves that tolerate spring chilling and frosts to harness the long photoperiods. Although there is nothing inherently cold sensitive about the C4 pathway, cold tolerant C4 grasses are rare and the additional C4 cycle and architecture introduce more potentially cold sensitive …

The role of SENSITIVE TO FREEZING6 in plant tolerance to stress
… the development of crops with greater stress tolerance. Identification of Arabidopsis mutants unable to tolerate stress is a powerful approach to investigate the molecular basis of stress tolerance in plants and so identify targets for modification. The Arabido psis mutant sfr6 (sensitive to …

Strategies to improve C4 photosynthesis, water and resource-use efficiency under different atmospheres, temperatures, and light environments
… of C4 plants to photosynthesize effectively at chilling temperatures is examined. In leaves of several C4 species, it was found that chloroplast volume, determined via confocal microscopy, is more than sufficient to support Rubisco contents that would not be limiting to photosynthetic CO2 …
