Fine mapping of the BnUC2 locus related to leaf up-curling and plant semi-dwarfing in Brassica napus
Studies of leaf shape development and plant stature have made important contributions to the fields of plant breeding and developmental biology. The optimization of leaf morphology and plant height to improve lodging resistance and photosynthetic efficiency, increase planting density and yield, and facilitate mechanized harvesting is a desirable goal in Brassica napus.

Plants are always exposed to dynamic light. The photosynthetic light use efficiency of leaves is lower in dynamic light than in uniform irradiance. Research on the influence of environmental factors on dynamic photosynthesis is very limited. Nitrogen is critical for plants, especially for photosynthesis.

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.

The performance and water use efficiency (WUE) of Chrysanthemum var. Marigold was evaluated under two moisture regimes, i.e., 100 % FC and 70 % FC imposed and maintained using gravimetric method. At 100 % FC, the plant height (30.33 cm), average plant spread (38.21 cm), number of primary branches/plant (5.67) and secondary branches/plant (4.67), number of leaves/plant (71.67), number of flowers/plant (136.75), average weight of individual flowers (7.21g), RWC (94.29%), root: shoot ratio (0.42), total fresh bio mass (153.09 g), flower yield (881.67 g / plant) and shelf life of 7.

A field experiment was conducted at research area of Department of Agricultural Meteorology, CCS Haryana Agricultural University, Hisar, during the kharif season of 2013-14. The main plots treatments consisted of four date of sowing (2 nd week of April, 4 th week of April, 2 nd week of May and 1st week of June) and the sub-plots consisted of three cotton varieties (HD 123, H 1098 and RASI 134). In the 2nd week of April sown crop consumed highest thermal and radiation indices, and efficiently converted the thermal/radiant energy into biomass production.

Alkaline/neutral invertase (A/N-INV), an enzyme that hydrolyzes sucrose irreversibly into glucose and fructose, is essential for normal plant growth,development, and stress tolerance. However, the physiological and/or molecular mechanism underpinning the role of A/N-INV in abiotic stress tolerance is poorly understood.

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.

Integration of optimal photosynthetic photon flux density (PPFD) and mycorrhization under in vitro conditions appears to have significant synergistic effect in enhancing the growth and survival of the medicinal orchid, Dendrobium chrysanthum under in vitro and ex vitro conditions. PPFD at 60 µmol m-2 s -1 was found to be optimal for root colonization for mycorrhizal association by fungi (73% colonization). The growth of mycorrhizal plantlets was observed to be superior at 60 µmol m-2 s -1 PPFD as compared to plantlets subjected to either lower or higher PPFD.

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.

Nitrogen is the major nutrient element required for the plant growth and development. In rice, development of varieties with improved nitrogen use efficiency will reduce the nitrogen fertilizer application. This study was investigating the genotypic differences in photosynthetic nitrogen use efficiency, nitrogen use efficiency, yield and yield related traits of 12 different rice genotypes under two different nitrogen levels viz., T1 and T2. Different physiological and agronomical characters were measured in selected 12 genotypes, growing in field.
