Development of Scutellar Epithelial Cells during Rice Embryogenesis, Studied by Chemical Fixation and Freeze-substitution Methods
Cuticular layer Freeze-substitution Oryza sativa Scutellar epithelial cell Tiny cell wall ingrowth
2009/8/5
The whole surface of rice embryo was continuously covered with a cuticular layer until 4 days after anthesis. The cuticular layer became intermittent at only the abaxial side of scutellum at 5 days an...
Variability in Nitrogen Fixation Activity among Soybean Cultivars Grown under Field Conditions
Cultivar difference Dry matter accumulation Nitrogen fixation Nodule dry weight Non-nodulating cultivar
2009/7/30
Variability in nitrogen fixation activity among soybean cultivars was examined under well-managed field conditions. Four and 15 soybean cultivars were grown in 1989 and 1991, respectively, along with ...
Enhanced Nitrogen Fixation Capabilities of Soybean Rhizobia by Inter- and Intra-specific Cell Fusion
(Brady) Rhizobium Cell fusion Nitrogenase Nodulation Protoplast Soybean
2009/7/28
A procedure for protoplast isolation and regeneration in rhizobia has been established. The use of 1% N-laurylsarcosine in pre-washing of the cells facilitated the cellular lysis by incubation for 1 h...
Characteristics of Nodulation and Nitrogen Fixation in the Improved Supernodulating Soybean (Glycine max L. Merr.) Cultivar ‘Sakukei 4’
Glycine max L.Merr. Growth Nitrogen fixation Root nodule Soybean Supernodulation
2009/7/24
Supernodulating soybean lines have more than several times as many nodules as normal cultivars. They are expected to have high nitrogen-fixing ability and enhanced productivity, but their yields have...

Difference in δ15N Signatures among Plant Parts of Perennial Species Subjected to Drought Stress with Special Reference to the Contribution of Symbiotic N2-fixation to Plant N
Actinorhizal plant δ15N 15N natural abundance method Nitrogen fixation Perennial plant
2009/7/24
The 15N natural abundance method has been widely used for evaluation of symbiotic N2-fixation. The method inevitably requires a reference plant that reflects soil derived δ15N similar to that in a N2-...
Reduction of Growth and Symbiotic Nitrogen Fixation in Soybean as Affected by the Site of Simulated Acid Rain Application
Acetylene reduction activity Acid rain Nodule Photosynthesis Soybean Symbiotic nitrogen fixation
2009/7/23
Reductions of growth and symbiotic nitrogen fixation were studied in soybean exposed to simulated acid rain (SAR) applied to different sites. Soybean cultivar Okuharawase was grown in 1/5000a pots und...
Effects of Waterlogging on Nitrogen Fixation and Photosynthesis in Supernodulating Soybean Cultivar Kanto 100
Glycine max Nitrogen fixation Photosynthesis Soybean Supernodulation Waterlogging
2009/7/23
The supernodulating soybean (Glycine max (L.) Merr.) cultivar Kanto 100 was previously characterized by superior nitrogen (N) fixation and photosynthesis, and resulting in high yields. However, this c...
Effect of CO2 Concentration,Temperature and N Fertilization on Biomass Production of Soybean Genotypes Differing in N Fixation Capacity
Biomass production Elevated [CO2] High temperature N fixation Photosynthesis Soybean (Glycine max) Supernodulation
2009/7/21
We tested the hypothesis that elevated CO2 concentration [CO2]-induced enhancement of biomass production of soybean is greater in a genotype that has a higher nitrogen (N) fixation capacity. Furthermo...
Estimation of the Amount of Symbiotic Nitrogen Fixation Based on the Relationship between Dry Matter Production and Evapotranspiration in Soybean
