Insights Into the Regulation of the Expression Pattern of Calvin-Benson-Bassham Cycle Enzymes in C₃ and C₄ Grasses.

ABSTRACT: C₄ photosynthesis is characterized by the compartmentalization of the processes of atmospheric uptake of CO₂ and its conversion into carbohydrate between mesophyll and bundle-sheath cells. As a result, most of the enzymes participating in the Calvin-Benson-Bassham (CBB) cycle, including RubisCO, are highly expressed in bundle-sheath cells. There is evidence that changes in the regulatory sequences of RubisCO contribute to its bundle-sheath-specific expression, however, little is known about how the spatial-expression pattern of other CBB cycle enzymes is regulated. In this study, we use a computational approach to scan for transcription factor binding sites in the regulatory regions of the genes encoding CBB cycle enzymes, SBPase, FBPase, PRK, and GAPDH-B, of C
