Under blue light, plant chloroplasts relocate to different areas of the cell. The photoreceptor phototropin 2 (phot2) mediates the chloroplast movement mechanism under excess blue light alongside the ...
Metabolic fluctuations in chloroplasts and mitochondria can trigger retrograde signals to modify nuclear gene expression. Mobile signals likely to be involved are reactive oxygen species (ROS), which ...
Drought is one of the most deleterious environmental conditions affecting crop growth and productivity. Here we report the important roles of a nuclear-encoded chloroplast protein, PsbP Domain Protein...
Polymorphic analyses of simple sequence repeat regions on chloroplast genomes in 34 vegetables were conducted using a set of consensus SSR primer pairs. A sufficient number of DNA markers were obtaine...
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...
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...
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...
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 ...
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...
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...
The natural populations of Rhododendron ripense Makino distributed in the San-in and Shikoku area, Japan, were investigated for the application in breeding materials. Genetic diversity was evaluated b...
We designed 74 primers (37 pairs) for the DNA amplification of 37 noncoding regions in the large single copy (LSC) and the small single copy region (SSC) of the chloroplast genome in the grass famil...
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...
摘要 利用叶绿体微卫星(cpSSR)分子标记对日本国内的7个日本落叶松(Larix kaempferi)群体遗传结构进行了研究。11对cpSSR引物中筛选出的3对多态性引物,共产生10个长度不同片段,在197个样品中组合出现10个不同的单倍型(haplotype)。各群体的单倍型差异较大。cpSSR基因座揭示了日本落叶松的遗传变异:平均等位基因数A=3.33,平均有效等位基因数NE=1.20,基...
