Elevated expression of PGR5 and NDH-H in bundle sheath chloroplasts in C4 flaveria species.
Cyclic electron transport around PSI has been proposed to supply the additional ATP required for C(4) photosynthesis. To investigate the nature of cyclic electron pathways involved in C(4) photosynthesis, we analyzed tissue-specific expression of PGR5 (PROTON GRADIENT REGULATION 5), which is involved in the antimycin A-sensitive pathway, and NDH-H, a subunit of the plastidial NAD(P)H dehydrogen...
متن کاملBUNDLE SHEATH DEFECTIVE2, a novel protein required for post-translational regulation of the rbcL gene of maize.
The Bundle sheath defective2 (Bsd2) gene is required for ribulose-1, 5-bisphosphate carboxylase/oxygenase (Rubisco) accumulation in maize. Using a Mutator transposable element as a molecular probe, we identified a tightly linked restriction fragment length polymorphism that cosegregated with the bsd2-conferred phenotype. This fragment was cloned, and sequences flanking the Mutator insertion wer...
متن کاملComparative Proteomics of Chloroplasts Envelopes from Bundle Sheath and Mesophyll Chloroplasts Reveals Novel Membrane Proteins with a Possible Role in C4-Related Metabolite Fluxes and Development
As the world population grows, our need for food increases drastically. Limited amounts of arable land lead to a competition between food and fuel crops, while changes in the global climate may impact future crop yields. Thus, a second "green revolution" will need a better understanding of the processes essential for plant growth and development. One approach toward the solution of this problem...
متن کاملThe Biochemical and Functional Properties of Thylakoid Protein Complexes from Mesophyll and Bundle Sheath Chloroplasts of Three Types of C4 Plants
Leaves of C 4 plants contain two distinct types of photosynthetic cells, mesophyll (M) and bundle sheath (BS) which are quite different organized both structurally and functionally. There are three C 4 subgroups based on differences in decarboxylating mechanisms: NADP-ME, NAD-ME and PEP-CK type [1]. The BS chloroplasts in NADP-ME subtype are agranal with structures like stroma lamellae of C 3 c...
متن کاملPhotophosphorylation in isolated maize bundle sheath chloroplasts and cells.
Isolated maize bundle sheath chloroplasts showed substantial rates of noncyclic photophosphorylation. A typical rate of phosphorylation coupled to whole-chain electron transport (methylviologen or ferricyanide as acceptor) was 60 mumol per hour per milligram chlorophyll) with a coupling efficiency (P/e(2)) of 0.6. Partial electron transport reactions driven by photosystem I or II supported phos...
