In cotyledon, on one hand, very weak GUS staining was observed in PARF8:GUS, but very strong was found in phyA-209 PARF8:GUS. In the shoot apical meristem, hypocotyle and root tip, on the other hand, phyA-209 PARF8:GUS exhibited weaker GUS activity than PARF8:GUS. Interestedly the same expression patterns of ARF8 resulting from disruption of PhyA have been observed in dark, white-light and far-red-light conditions.

结果表明，无论在黑暗、白光和远红光条件下，PhyA突变均明显提高幼苗子叶和叶片中ARF8的表达水平，但明显降低幼苗下胚轴、茎尖和根尖中的表达水平。

The transient expression experiment with gus gene showed that mwcsllO promoter was induced by high salt and low temperature and promoted expression of structural genes in both monocotyledonous and dicotyledonous plants.

对gus基因瞬时表达实验表明，在单子叶和双子叶植物中，mwcS12O启动子均受低温和高盐逆境诱导，启动结构基因的表达，显示其在作物抗逆基因工程改良中的应用前景。

22 Of 22 pairs EST-SSR primers from Chinese cabbage/rape respectively had amplification products in soybean,wheat and maize,the rate of amplification was 81.8%,95.4%,100%,respectively;10 of 22 pairs EST-SSR primers showed polymorphism in monocotyledons wheat and maize,13 in dicotyledons oilseed rape and soybean,7 in both monocotyledonous and dicotyledonous crops.

（1）30对小麦EST-SSR引物中，有29，28和26对引物分别在玉米、油菜和大豆中有扩增产物，可扩增率分别为96.7%，93.3%和86.7%；其中分别有12对和9对引物在单子叶作物小麦和玉米及双子叶作物大豆和油菜中的扩增产物显示多态性，有4对引物在4种作物中的扩增产物均显示多态性。

These individual characters are similar to those of most aquatic plants in monocotyledonous Helodiales and dicotyledonous Nymphaeales, which reflects the phylogenetic relationships of Iris from aquatic plants to xerophil.

这些个体性状与单子叶沼生目和双子叶睡莲目多数水生植物相似，从一定程度上可以反映鸢尾属植物从水生到旱生的系统发生上的关系。

The research advance on organogenesis, somatic embryogenesis and protoplast regeneration system of soybean are introduced in this paper.

终于在20世纪80年代初期有了转机，人们选择了幼胚、幼胚子叶或胚轴为外植体，用异常高浓度的植物生长调节物质，建立了大豆的体细胞胚胎发生和器官发生再生系统。

Are preparatively cultured in the differentiation culture mediums(IBA 1 mg/L, BA0.4 mg/L) for two days, and AS is added in preparative culture medium and MSo bacterial liquid that has been centrifugated. The extents of colouration are not identical.

影响瞬时表达的因素很多，本实验主要对四个因素进行测试：预培养天数(1天、2天)、不同激素配比的分化培养(IBA 1.0mg/L BA 0.4mg/L、IBA 0.2mg/L BA 2mg/L)、是否加入乙酰丁香酮、外植体类型(子叶、真叶、下胚轴、根)。

This one mode pays close attention to network credence foundation of the businessman very much.
