Analysis of potential redundancy among Arabidopsis 6-phosphogluconolactonase isoforms in peroxisomes.

abstract：:Most terrestrial plants use C3 photosynthesis to fix carbon. In multiple plant lineages a modified system known as C4 photosynthesis has evolved. To better understand the molecular patterns associated with induction of C4 photosynthesis, the genus Flaveria that contains C3 and C4 species was used. A base to tip matura...
