Light and photosynthesis

Ebook "Plant developmental biology - Biotechnological perspectives (Volume 2)" focuses on development-related areas, including tissue culture (somatic embryogenesis, microspore embryogenesis, somaclonal variation), plant processes (photosynthesis, seed maturation and seed proteins, fatty acids, vitamins, alkaloids, flower pigments and scent), signalling (amino compound-containing lipids, auxins, cytokinins and light), and molecular genetics of developmental regulation (RNA silencing, DNA methylation, epigenetics, activation tagging, homologous recombination and synthetic promoter engineering).

In artificial photosynthesis process the photocatalyst-enzyme attached system is a best strategy to utilize solar energy for solar chemical/fuels production. Herein, we prepared a solar light active graphene-based photocatalyst received by the covalent attachment of 9-aminoanthracene (AA) chromophore with chemically converted graphene (CCG) for highly efficient 1,4-NADH regeneration (79.9 %) and conversion of α-ketoglutarate (α-KG) in to Lglutamate (L-GM) (88.3 %) in 2 hrs.

Euglena gracilis, a unicellular phytoflagellate within Euglenida, has attracted much attention as a potential feedstock for renewable energy production. In outdoor open-pond cultivation for biofuel production, excess direct sunlight can inhibit photosynthesis in this alga and decrease its productivity.

Photosynthesis plays a vital role as an energy source for plant metabolism, and its efficiency may be drastically reduced owing to abiotic stresses. Moso bamboo (Phyllostachys edulis), is a renewable and versatile resource with significant ecological and economic value, which encounters high light stress with large amplitude in natural environment. However, the gene expression profiles in response to high light were elusive in bamboo.

Photosynthesis is able to convert solar energy into chemical energy in the form of biomass, but the efficiency of photosynthetic solar energy conversion is low. Chlorophyll fluorescence measurements are rapid, nondestructive, and can provide a wealth of information about the efficiencies of the photosynthetic light reaction processes.

Shading includes low light intensity and varying quality. However, a low red/far-red (R/Fr) ratio of light is a signal that affects plant growth in intercropping and close- planting systems. Thus, the low R/Fr ratio uncoupling from shading conditions was assessed to identify the effect of light quality on photosynthesis and CO2 assimilation.

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.
