Abstract
We have recently reported high activities of enzymes associated with C4 photosynthesis in cells around the vascular system in C3 plants (Nature, 415: 541-545). One of these C4 enzymes is of pyruvate orthophosphate dikinase, and its role in C3 plants is unclear. Arabidopsis contains only one ppdk gene, although in other species a single gene produces two transcripts due to two different promoters. The aim is to determine whether the single gene leads to the production of two proteins via alternative promoter elements, to test the subcellular location(s) of PPDK protein, and test whether PPDK regulates synthesis of lignin in the xylem, and storage protein production (and thus nutritional quality) in seeds.
