Studies on Ultrastructure and Function of Photosynthetic Apparatus in Rice Cells : IV. Effect of low dose and intermittent fumigation of ozone on the ultrastructure of chloroplasts in rice leaf cells
Chloroplasts oryza sativa L Ozone fumigation Swelling Thylakoid membranes Ultrastructure
2009/8/6
Young rice plants (Oryza sativa L. cv. Koshihikari), which are 4 week old plants grown in a potting soil under natural light at 28/27°C in day/night, were intermittently fumigated with 0.1 ppm ozone f...
Studies on Culture of Cells and Tissues of Crop Plants:I. Survey on enzymatic isolation and culture of rice leaf sheath protoplasts
BSA Cell activity Cellulase "Onozuka" R-10 Protoplasts MS-medium Rice leaf sheath
2009/8/6
To establish a method for isolation and culture of rice protoplasts, enzyme solution compositions, culture conditions, and the selection of cultivars and tissues as materials were examined. The result...
Relationship between Salinity-Induced Damages and Aging in Rice Leaf Tissues
Aging Chlorophyll Cl content Na content Na/K ratio Rice Salt stress Ultrastructure
2009/7/29
Segments of rice leaves at different nodal positions were incubated in NaCl solutions for various periods, and the chlorophyll content, Na content, Cl content, Na/K ratio and the ultrastructure of exc...
Pretreatment with Antioxidants Decreases the Effects of Salt Stress on Chloroplast Ultrastructure in Rice Leaf Segments (Oryza sativa L.)
Antioxidants Chloroplasts Oryza sativa L. Salt stress Thylakoids Ultrastructure
2009/7/29
We investigated the kinds of active oxygen species leading to the destruction of chloroplast ultrastructure in salt-stressed rice plants. After the seedlings were grown for 3 wks, leaf segments (5 mm ...
Enhancement of Rice Leaf Photosynthesis by Crossing between Cultivated Rice,Oryza sativa and Wild Rice Species,Oryza rufipogon
Leaf photosynthesis Oryza rufipogon Oryza sativa Rice Rubisco Rubisco activase Wild rice species
2009/7/29
To study whether wild rice species have genes that may increase potential photosynthetic capacities of rice cultivars, we generated BC2 populations by reciprocally backcrossing Oryza rufipogon (W630)...

Rice Leaf Photosynthesis as a Function of Nitrogen Content and Crop Developmental Stage.
Temporal and Spatial Variations of Carbohydrate Content in Rice Leaf Sheath and Their Varietal Differences
Carbohydrate Enzyme Leaf sheath Spatial variation Temporal change Variety
2009/7/27
In rice plant, carbohydrates accumulated in leaf sheaths before heading are translocated to grain and affect yield formation greatly. To clarify the intrinsic mechanism of carbohydrate metabolism in t...
Antioxidant Capacity and Damages Caused by Salinity Stress in Apical and Basal Regions of Rice Leaf
Age Antioxidant enzyme NaCl Reactive oxygen species Rice
2009/7/21
We investigated the mechanisms of increased sensitivity to Na+ in the apical and basal regions of the rice leaf under salinity. Three-week-old plants were treated with 200 mM NaCl in hydroponic cultur...
