查询词典 aster yellows

Based on Phylogenetic analysis of sequences from these 10 phytoplasmas using PAUP (phylogenetic analysis using parsimony) software, these phytoplasmas could be classified into five groups. These phytoplasmas groups and strains were: group 1, sweetpotato witches' broom, mainland China strain of sweetpotato witches' broom, peanut witches' broom and Ipomoea obscura witches' broom; group 2, loofah witches' broom; group 3, elm yellows; group 4, rice yellow dwarf and sugarcane white leaf disease; group 5, New Jersey strain of aster yellows and western strain of aster yellows.

进一步比较CWB-YN株系核糖体蛋白基因rps3基因编码的氨基酸序列同源性，结果与16S rI–B亚组的翠菊黄化病植原体(Aster yellows，AY)和长春花黄化病植原体(Periwinkle yellows，PY)的同源性最高，分别达98.1%和100%。

The absorption spectrum center wavelength of dolomite is near 232 μm is shorter than 235 μm of limestone,and thus RBD7 and RBD8 can be employed effectively to identify dolomite and limestone,respectively. Felsic rocks show AlOH and Fe3+ absorption characteristics in the VNIRSWIR region,while the maficultramafic rocks show Fe2+ and Fe,MgOH absorption features,hence the use of different valence state of iron and secondary minerals can distinguish them:ASTER band2/band1 represent Fe3+ distribution,ASTER band2/band1 represent the Fe2+ distribution,RBD6 can estimate the AlOH mineral abundance. Psammitic/pelitic schist containing phengite,chlorite,stilpnomelane,as well as the weathered surface covered by clay minerals,exist characteristic absorption spectrum in the 221 μm(band 6),and has a high reflectance in 165 μm(band 4),while the blueschist/greenschist show high reflectance in the 221 μm(band 6),and it exit low reflectance in 165 μm(band 4),and blueschist/greenschist appear low ASTER band4/band6 ratio.

白云岩的CO2-3吸收谱带中心波长位于232〖KG*3〗μm，与灰岩的CO2-3 吸收谱带中心波长位置235 μm相比，具有向短波长方向移动的特点，据此可以利用RBD7、RBD8分别有效的识别白云岩和灰岩；长英质岩石显示AlOH和Fe3+ VNIRSWIR吸收特征，而基性超基性岩石显示Fe2+和Fe、MgOH特征，利用不同的铁价态和次要矿物可以区分它们：ASTER band2/band1代表了含Fe3+矿物分布信息、ASTER band5/band4代表了含Fe2+矿物分布信息、RBD6可以估计AlOH矿物的丰度；砂质/泥质片岩含较多的多硅白云母、绿泥石、黑硬绿泥石以及风化后表面覆盖的其它粘土矿物，在221 μm（band 6）存在有特征的吸收谱带，并且在165 μm（band 4）具有较高的反射率，而蓝片/绿片岩在221 μm（band 6）反射率较高，不具有明显特征吸收谱带，同时其在165 μm（band 4）反射率较低，因此蓝片/绿片岩ASTER band4/band6 比值低。

Cross yellow monokaryons with white monokaryons, the fruitbody color of hybrid will show light yellows. Meanwhile, light yellows are not homochromatism, but a serial of transitional ones.
