稻属

All the known cases of materials carrying the Xa4 gene resistantto bacterial leaf blight are found to belong to the Hsie rice.

鉴于已发现的具白叶枯病抗性基因叱。的材料均属釉稻。

The results showed that the microbial community could degrade 39.6% of rice straw gross weight within five days. When the culture medium volume was 1/5 of the whole and pH at 6 on the 5 days culture, the CMC reached the highest of 14 IUml^(-1). During the rice straw degradation, more than ten kinds of products were detected using GCMS. DGGE detected the dynamic change of microbial community composition, and the microbial composition changed greatly in different periods. The phylogenetic tree derived from 16s rDNA sequence was found that the closest relatives belong to Clostridium sp., Brevibacillus sp., Bartonella sp.、Bacteroidetes sp.

5d后稻秆总减重量达到39.6%，在培养基占总体积1/5、pH=6、培养第5天时纤维素内切酶活性表现最高，达到14IUml^(-1)；培养过程中发酵液中有10余种挥发性产物，且不同时期产物的种类和浓度变化很大，从DGGE图谱发现在培养不同时期菌种组成有很大差异，通过各条带近缘种16s rDNA扩增信息构建系统树可见，各条带近缘种分别归属Clostridium、Brevibacillus、Bartonella、Bacteroidetes4个属。

In this study, we sequenced the intron 2 of mitochondrial nad1 gene to study the phylogeny of Oryzeae, in particular emphasizing the systematic position of Porteresia, a monotypic genus of Oryzeae with the only species P. coarctata.

本研究选用nad1基因的第2内含子序列探讨了稻族Oryzeae的系统发育关系，并着重分析了单型属Porteresia的系统学位置，并在此基础上探讨了nad1基因内含子序列的系统学意义以及空位性状在系统发育重建中的价值。

The inhibitory activity of Echcin to 14 strains of phytopathogenic bacteria was tested using paper plate method.

采用纸碟法测定了Echcin 对5 个属植物病原细菌共14 个菌株的抑制作用，琼脂稀释法测定了Echcin 对12 种植物病原真菌的抑制作用，在此基础上开展了Echcin 对番茄早疫病和稻白叶枯病的温室盆栽试验，同时开展了Echcin 对小麦纹枯病的田间小区试验。

False smut is a worldwide rice disease caused by Ustilaginodea virens Tak.

稻曲病是世界性水稻真菌病害，致病菌属于子囊菌纲球壳菌目麦角菌科绿核菌属Ustilaginodea virens

Rice kernel smut is a kind of common disease on hybrid rice which is causedby Neovossia horrida fungus.

稻粒黑粉病是由稻尾孢黑粉菌属稻粒黑粉菌引起的一种杂交稻制种上的常见病害。

The results of dendrogam were consistent with the previous conclusion of morphologic classification and cytotaxonomy, and suggested RAPD was suitable for analysis of phylogenetic relationships among species of Oxya .

聚类图所呈现的种间关系与传统的形态及细胞分类学结果基本一致，5种稻蝗亲缘关系的远近程度得以清楚显示，说明RAPD技术在稻蝗属种间分子系统学研究中具有很好的适用性。
