Ultrastructural Changes in Chloroplast and Phloem of Rice Leaves during Senescense under Different Nitrogen Supply
Chloroplast Nitrogen deficiency Phloem Rice leaf Senescense Ultrastructure
2009/8/6
Rice seedlings of 7.2 in leaf age were transplanted into pots containing culture solution. The control plants received the complete solution and the N-deficient plants received the -N solution. Sample...
Light Dependency of Salinity-Induced Chloroplast Degradation
Chlorophyll Chloroplast Cl content Na content Oxidative reaction Rice Salt stress Ultrastructure
2009/7/29
The contents of Na, K, Cl, chlorophyll and the foliar ultrastructure of rice seedlings grown in NaCl solution at various concentrations were investigated under light and dark conditions. The seedlings...
Pretreatment with a Low Concentration of Methyl Viologen Decreases the Effects of Salt Stress on Chloroplast Ultrastructure in Rice Leaves (Oryza sativa L.)
Ascorbate peroxidase Catalase Methyl viologen Oryza sativa Salt stress Superoxide dismutase Thylakoids Ultrastructure
2009/7/29
We investigated the effects of pretreatment with a low concentration of methyl viologen (MV) on the salinity-induced chloroplast degeneration in rice seedlings. The seedlings grown in hydroponic cultu...
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 ...
Correlation between Chloroplast Ultrastructure and Chlorophyll Fluorescence Characteristics in the Leaves of Rice (Oryza sativa L.) Grown under Salinity
Chlorophyll fluorescence Chloroplast Rice (Oryza sativa L.) Salt stress Ultrastructure
2009/7/21
The seedlings of Oryza sativa L. cv. Nipponbare grown by hydroponic culture for 3 wks were treated with 75, 100, 150 and 200 mM NaCl for 14, 14, 6 and 3 days, respectively, and examined for chloroplas...
Salt Tolerance of the Chloroplast Thylakoid Membrane in Wild Oryza Species, Oryza. latifolia Desv
SDS–PAGE Photosynthesis Salt tolerance Thylakoid membrane protein
2009/7/8
In our previous report, the wild Oryza species O. latifolia showed higher salt–tolerance than the standard salt tolerant rice species, SR26B. To elucidate the mechanism of salt tolerance in O. latifo...
Analysis of Chloroplast Ultrastructure, Photosystem Ⅱ Light Harvesting Complexes and Chlorophyll Synthesis in a Chlorophyll-Less Rice Mutant W2555
chloroplast ultrastructure photosystem Ⅱ chlorophyll synthesis precursors chlorophyll-less mutant
2009/1/7
A comparative study on chloroplast ultrastructure and light harvesting complex of photosystem Ⅱ (LHC Ⅱ) was conducted between a new rice mutant (W2555) and its wild type (WT). The chloroplasts of W255...
