C4 photosynthesis
-
Sugarcane served as the model plant for discovery of the C4 photosynthetic pathway. Magnesium is the central atom of chlorophyll, and thus is considered as a critical nutrient for plant development and photosynthesis.

Carbonic anhydrase (CA) catalyzes the hydration of CO2 in the first biochemical step of C4 photosynthesis, and has been considered a potentially rate-limiting step when CO2 availability within a leaf is low. Previous work in Zea mays (maize) with a double knockout of the two highest-expressed β-CA genes, CA1 and CA2, reduced total leaf CA activity to less than 3% of wild-type.

Foxtail millet (Setaria italica) has been developed into a model genetical system for deciphering architectural evolution, C4 photosynthesis, nutritional properties, abiotic tolerance and bioenergy in cereal grasses because of its advantageous characters with the small genome size, self-fertilization, short growing cycle, small growth stature, efficient genetic transformation and abundant diverse germplasm resources.

Crassulacean acid metabolism (CAM) photosynthesis is an important carbon fixation pathway especially in arid environments because it leads to higher water-use efficiency compared to C3 and C4 plants. However, the role of DNA methylation in regulation CAM photosynthesis is not fully understood.

C4 photosynthesis is a key domain of plant research with outcomes ranging from crop quality improvement, biofuel production and efficient use of water and nutrients. A metabolic network model of C4 “lab organism” Setaria viridis with extensive gene-reaction associations can accelerate target identification for desired metabolic manipulations and thereafter in vivo validation.

2016 marked the 50th anniversary of the discovery of Hatch-Slack pathway, more popularly known as the C4 photosynthetic pathway in sugarcane leaves. Since then, there had been a significant development in understanding the C4 syndrome and its evolutionary background. C4 photosynthesis produces almost a quarter of the world’s entire primary productivity, despite having merely a few plant lineages to compete with. This clearly depicts the extraordinary capacity of the system to effectively trap carbon and converting it into plant biomass.

C4 plants have been classified into three subtypes based on the enzymes used to decarboxylate C4 acids in the bundle sheath cells (NADP-ME, NAD-ME and PEPCK pathways).

Maize bsd2 (bundle sheath defective2) is a classical C4 mutant with defective C4 photosynthesis, accompanied with reduced accumulation of Rubisco (ribulose bisphosphate carboxylase oxygenase) and aberrant mature chloroplast morphology in the bundle sheath (BS) cells.

NADP-malic enzyme (NAPD-ME), and pyruvate orthophosphate dikinase (PPDK) are important enzymes that participate in C4 photosynthesis. However, the evolutionary history and forces driving evolution of these genes in C4 plants are not completely understood.

The C4 photosynthetic carbon cycle can be explained as the elaborated addition to the C3 photosynthetic pathway. It is a unique series of biochemical, anatomical and regulatory gene characteristics that concentrate CO2around the carboxylating enzyme Rubisco, thereby increasing photosynthetic efficiency during high rates of photorespiration. The C4 photosynthetic pathway has evolved as an adaptation to high light intensities, high temperatures and dryness, therefore in the warmer climates of the tropical and subtropical dominating the grassland floras and biomass production.

A new “Green revolution” is needed in world agriculture to increase crop yields for food and bioenergy, because gains from conventional breeding method are less than world population growth. Efforts to increase crop productivity must also consider global change. Carbon-dioxide, methane and other greenhouse gases in atmosphere leads to global warming. Photosynthesis is the single most effective natural regulator of carbon dioxide in the Earth’s atmosphere. It is timely to consider what new opportunities exist in the current “omics” era to engineer increases in photosynthesis.
