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.

从spacer序列堆衍的亲缘演化树显示这10种植物菌质体可分为5群：第一群，甘薯簇叶病、甘薯簇叶病、花生簇叶病及细花牵牛簇叶病等菌质体；第二群，丝瓜簇叶病菌质体；第三群，榆树黄化病菌质体；第四群，水稻黄萎病及甘蔗白叶病菌质体；第五群，翠菊黄化病菌质体。

The road through the forest one of those wagon-tracks that were being opened from the clearings of the settlers, and that wound along beneath trees of which those now seen in Kentucky are the unworthy survivors--oaks and walnuts, maples and elms, centuries old, gnarled, massive, drooping, majestic, through whose arches the sun hurled down only some solitary spear of gold, and over whose gray-mossed roots some cold brook crept in silence; with here and there billowy open spaces of wild rye, buffalo grass, and clover on which the light fell in sheets of radiance; with other spots so dim that for ages no shoot had sprung from the deep black mould; blown to and fro across this wagon-road, odours of ivy, pennyroyal and mint, mingled with the fragrance of the wild grape; flitting to and fro across it, as low as the violet-beds, as high as the sycamores, unnumbered kinds of birds, some of which like the paroquet are long since vanished.

通过这些车皮了正在从定居者的结算开首曲目森林一条道路，并沿下树木的伤口现在看见的，在肯塔基州是不值得的幸存者-橡树和胡桃，枫树和榆树，百年老，格纳尔德，大规模，下垂，庄严，通过投掷下来的拱门只有一些孤立的金矛的太阳，而超过其灰mossed基层一些冷布鲁克在沉默中悄悄地，与在这里和那里的野生黑麦，水牛汹涌的休憩用地草，三叶草上的光板下跌的光芒；与其他景点，非常昏暗，对于没有拍摄了从深黑模具；被炸来回穿越这车，路，常春藤气味，薄荷油，薄荷涌现年龄，夹杂着的野生葡萄香味，飞来飞去往返境而过，像紫床低，高的桑树，种鸟类的一间，其中一些像paroquet是早已消失了。

Producing PHAs,and then were orientationally inserted into a prokaryotic expression vector pBV220. By analyzing the bioactibity and function of their products, the biological function of phaA, phaB and phaC was confirmed. These have been done in our laboratory. To make better use of the three genes by plant bioreactor, two groups of different plant expression vectors that can be used to produce PHAs in different plants were constructed, and the transformation of PHA in Oxalis triangnlaris has been preliminarily reseached.The following is the main results:Three plant expression vectors pBI121-A,pBI121-B and ubquiting-C, which can be used to be transformed into Oxalis triangularis were respectively constructed by using the phaA, phaB and phaC.

菌株的亚克隆基因组片段中，分离出phaA、phaB和phaC三个基因片段，定向克隆至原核表达载体pBV220，通过对其生物活性与功能分析，确证了基因phaA、phaB和phaC的生物学功能；为了通过植物生物反应器对这三个基因进一步研究利用，本实验利用这三个基因构建了两组可用于不同植物生产PHA的真核表达载体，并对紫叶酢浆草进行PHA基因遗传转化的初步研究，获得主要结果如下：利用克隆的phaA、phaB、phaC三个基因分别构建了可用于转化紫叶酢浆草表达载体pBI121-A、pBI121-B、uBquiting-C；可用于玉米转化的种子特异性表达载体p7S-A、pBI121-S-B、uBquiting-C。

Mushroom bodies and antennal lobes in Oxycetonia jucunda were conspicuous. Calyces and lobes of the mushroom bodies.were much developed. In contrast, calyces of Ambrostoma quadriimpressum and Henosepilachna vigintioctomaculata were extremely undeveloped. However, the postretinal fibres and circumpharyngeal nerves of Ambrostoma quadriimpressum were highly developed. In the three beetles, 5-HT immunoreactivity was present in all neuropils of the brain and the suboesophageal ganglion. The pattern of 5-HT immunoreactivity and the localization of immunoreactive somata which often clustered into groups were similar among these beetles, while the immunoreactivity intensity was distinct, especially in the lamina.

结果显示，分类地位相近的三种甲虫脑结构大小相差悬殊：小青花金龟脑结构相对发达，蕈形体结构显著，具有发达的冠和叶，嗅叶发达；马铃薯瓢虫和榆紫叶甲的冠极度退化，嗅叶相对不发达；但榆紫叶甲具有十分发达的网膜后纤维和围咽神经。5-HT阳性纤维在三种甲虫的所有神经纤维网中几乎都有分布，且反应模式相似，但各神经纤维网特别是神经节层染色强度差异显著。5-HT阳性胞体有成群分布现象，且在三种甲虫脑中的空间分布位置基本一致。

Ye Wen a life hard, but the leaf asked that still positively faced, as soon as changes the son from a wealthy family the manner, to the coal factory works as the coolie, relies on one's own effort to revive. Japanese general three pu are one military crazy, he takes the reward by the rice, invites the Chinese to strike the field and the Japanese forces compares notes, observes and emulates the Chinese martial arts. Ye Wen good friend Wu Chilin is striking the field to shoot by the Japanese forces, does not know the circumstances of the matter Ye Wenwei seeks for Wu Chilin to arrive strikes the field. Witnessed that the Japanese forces murder process, Ye Wen the grief and indignation gives vent to finally the heart, by an enemy ten, attacks fiercely the Japanese!

I saw her let go of the branches, I saw her lift her honeyed muzzle into the leaves, and her thick arms, as though she would fly - an enormous bee all sweetness and wings - down into the meadows, the perfections of honeysuckle and roses and clover - to float and sleep in the sheer nets swaying from flower to flower day after shining day.

我看见她松开枝条，我看见她将涂满蜂蜜的嘴和粗大的胳膊，伸进叶子，仿佛要飞起来——一只巨大的蜜蜂拥有蜜和翅膀——飞进草地，飞进美丽的金银花、玫瑰和三叶草丛中——漂浮并沉睡在透明的网中，从一朵花飞到另一朵花在一个接一个明亮的日子。
