When grown in the light and with nutrition as the limiting factor, the wild type was less influenced due to its capability of photosynthesis and quickly became predominant over the mutant that has no photosynthetic apparatus. However, when grown heterotrophically in the dark, the mutant remained less competitive than the wild type, showing that the euglenoid proplastids play a role in competition.
在光照情况下,当营养物质成为限制因子时,由于具有光合能力野生型生长受影响较小,在与没有光合器的突变株的竞争中很快地显示出优势;在黑暗中二者均只能以异养方式生长,但突变株仍然处于竞争弱势,显示原质体结构对于生存竞争的作用。

In conclusion, the lag phase of Streptococcus thermophilus was shorten in the eutrophy culture medium, and the time achieving the culminated point of logarithmic phase was shorted also, at the same time, the stationary phase lengthened. After secondary culture, Streptococcus thermophilus reached directly the log phase hardly through the lag phase, and then quickly reached the decline phase. There were more relations of the metabolic regalities of the three kinds of nutritive substances with the super-concentrated incubation process of Streptococcus thermophilus: the more the number of the bacteria, the quicker the metaboling, while the fewer, the slower the metabolism. Moreover, there apparently existed morphologic changes in this course, and there maybe existed the apoptosis, which correlated with bacteria propagation and acid producing. With the culture time postponed, the nutritive substances in the culture medium lacked also, and the morphologic change and apoptosis appeared more obviously.
结果表明,嗜热链球菌在营养丰富的培养基中的生长延滞期缩短,到达对数生长顶点的时间变短,稳定期的时间延长,当经过二次培养后,嗜热链球菌几乎不经过延滞期直接到达对数期,平稳期持续的时间较短,很快到达衰亡期;嗜热链球菌在超浓缩培养过程中三大营养物质的代谢规律也同它的培养过程有很大的关系,菌数多,其代谢旺盛,菌数降低其代谢速度减慢;嗜热链球菌在超浓缩培养过程中存在着明显的菌体形态变化,并可能存在着细胞凋亡,与菌体增殖和产酸规律密切相关,随着培养时间延长,培养基中营养物质变得贫乏,菌体形态变化和细胞凋亡的情况愈加明显。

"We knew that exercise increases bone size and strength, and that the skeleton is most responsive to exercise during the crucial growing years around puberty when you reach adult size and strength," Warden said."We also knew that bones are not as responsive to exercise when you are older."
"我们知道锻炼能促进骨骼生长和提高其坚硬度,而在骨骼达到成人比例和硬度之前,在青春期的关键生长时期对锻炼的反应是最敏感的," Warden说,"正如我们同样知道的那样,当年老以后,骨骼对锻炼就不那么敏感了。"

Result: The inductivity of leaves was the highest about 87.5%, followed with the stem section and leafstalk; The inductivity of nutrient medium such as MS, B5 callus was higher than the ones like H, SH and the White callus amended one; It was found that low-grade Phvalue benefits the growth of callus. The experiment result showed that different pH showed little difference in quality. The best condition of culture was 25 ℃in temperature. Conclusion: The best culture condition for callus was the leaves as explantation.
结果:叶片的诱导率最高,为87.5%;茎段次之,叶柄较差;培养基MS,B5愈伤组织诱导率较高,达到了80%以上,高于培养基H,SH和改良White的愈伤组织诱导率;偏低的pH对愈伤组织生长有利,出愈率高,但从愈伤组织生长质量方面看,不同pH差异不明显;愈伤组织诱导最适温度为25 ℃。

Three RNAi target sites (named as Abil1, Abil2, Abil3) targeting the E3B1 (NCBI: NM-024397), an identified target sites and positive control GAPDH-A were selected. The pGenesil-1 eukaryotic expression vectors with the neoR mark and GFP green fluorescent mark were selected to construct E3B1 RNAi plasmid. The effect of RNAi targeting various sites on E3B1 genes expression was evaluated by testing the transfection efficiency with fluorescence microscope and western blot. The most effective siRNA in inhibiting E3B1 genes were screened. The most effective siRNA in inhibiting E3B1 genes screened and used to transfect the neuronal cells. After that, the inhibitor of axon growth was added and the axon growth was observed. Result: The siRNA expressing plasmids targeting the E3B1 were constructed successfully.

The culm length, panicle length, spikelets per panicle and panicle exsertion were evaluated by using F2:3 population including 200 lines, derived from a cross of indica and japonica Milyang23/Jileng1 under five different environments of Beijing (natural normal growing environment), Kunming (natural low temperature condition), Gongzhuling of China and Chuncheon of Korea (natural normal growing environment and cold water irrigation), and QTLs of these traits were analysed by using SSR markers.
以籼粳交密阳23/吉冷1号200个F2:3家系作为作图群体,在北京、昆明、公主岭、韩国春川(正常生长环境和冷水胁迫)等5种不同生长环境下进行了水稻秆长、穗长、穗粒数和穗抽出度等主要农艺性状的异地鉴定,并利用SSR标记进行了上述农艺性状的QTL分析。
