In order to enhance its resistance to bacterial blightand lepidopteran such as leaffolder, striped stem borer and yellow stem borer etc, we intergessed Xa21 and Bt genes into the genetic background of 93-11 by backcross scheme, combining with molecular marker-assisted selection and phenotypic selection. Through three backcross and two self generations, eight families that have homozygous Xa21 and Bt genes were obtained in the BC3F3 families. Two families show higher recovery percentage of 93-11 even up to 90.59%.

为了进一步提高其对白叶枯病的抗性、同时增加其对水稻鳞翅目害虫（如稻纵卷叶螟、二化螟和三化螟等）抗性，利用常规回交育种方法和结合分子标记辅助选择将Xa21基因和Bt基因同时导入93-11中，在BC3F3家系中筛选到8个家系含纯合的Xa21基因和Bt基因，其中有两个家系与93-11比较其遗传背景的回复率很高，达到90.59%。

Grass of willow leaf horsewhip belongs to herb of perennial of horsewhip female division, formal name: Verbena Bonariensis illustrious name: Purpletop Verbena, alias: Long bine horsewhip is South-American horsewhip grass, careless, originate in South America formerly of Brazil, Argentine and other places, the flower is cyme, small tubular flower is worn be born at spending cauline coping, open amaranth or lilac flower, along with spends a bine to consider individual plant tall to make an appointment with 100-150 centimeter, liu Xie is crossed opposite, the primary part of a historical period after sowing is elliptic brim somewhat notch, beautiful bine is smoked tall the Xie Zhuai after is the slightness leaf that be like willow shape the brim still has pointed notch, the bine is a square this a little bit very special, entire individual plant has cilium to feel the feeling that pricks thorn a bit, the meeting in ground of be out of office is cross of plant of fringy horsewhip female division with a few congeneric flowers, so often a few inflorescence upright among Yu Jusan and fringy model state plant appears.

柳叶马鞭草属于马鞭草科多年生草本植物，学名：Verbena bonariensis英名：purpletop verbena，别名：南美马鞭草。长茎马鞭草，原产于南美洲，花为聚伞花序，小筒状花着生于花茎顶部，开紫红色或淡紫色花，连同花茎算株高约100-150公分，柳叶为十字对生，播种后的初期叶为椭圆形边缘略有缺刻，花茎抽高后的叶转为细长型如柳叶状边缘仍有尖缺刻，茎为正方形这点十分非凡，全株都有纤毛摸起来有点刺刺的感觉，在野地里会与一些同属花为穗状的马鞭草科植物杂交，所以常有一些花序介于聚伞与穗状的中间型态植株出现。

Its trees include big leaf maples, western hemlock, and Sitka spruce.

Complexity and diversity of plant species, some species tend to constitute a layer of film in various communities, or dominant plant , such as Lauraceae GUI shell is thick, Chen hook camphor, Euphorbiaceae large sand leaves, Yunnan big-leaf sand, the Sterculia Sterculiaceae, etc..

植物种类复杂多样、某些种属往往构成各个群落或层片的优势植物，如樟科的厚桂壳属、陈氏钩樟、大戟科的大砂叶、云南大叶砂、梧桐科之假苹婆等。

Although classic neuroimaging features of RPLS with involvement of the posterior head regions are easily recognized, features that may generally be regarded as atypical were often present in our patients, such as significant anterior involvement, cortical lesions, recurrent RPLS episodes, foci of permanent injury, hemorrhage into lesions, and unilaterality (Figure 1). High signal intensity on T2-weighted image lesions can occur in regions other than the parieto-occipital areas, frequently involving the frontal lobes, basal ganglia, thalami, or brainstem.

可逆性后部白质脑病综合征典型的神经影像学表现为大脑后部受累，尽管这一点很早就被公认；但可逆性后部白质脑病综合征不典型的神经影像学表现，在本文的患者中则更常见，如：大脑前部明显受累、皮层出现病灶、可逆性后部白质脑病综合征再次发作、脑永久性损伤灶形成、病灶内出血、仅见单侧病灶（图1）；T2像常可于额叶、基底节区、丘脑、脑干等顶-枕叶以外的区域见高信号病灶。

In 5 to August every year during this period is the period of harvest, cut stems and leaves together, such as with the soil should be dry cleaned, and then cut hay cutter about 5 cm above-like stems and leaves, according to the bake - Green tea processing methods, the fixation, rolled, pieces of solution, drying or dry fried, that is to become the beginning of the pentaphyllum tea products, refined plastic, bag in the form of packages made of.

在每年5～8月这段时间内是收割期，将茎叶一起割下后，如带有泥土的，应洗净晾干，再用铡刀切成5厘米左右段状茎叶，按制烘青绿茶方法加工，经杀青、揉捻、解块，烘干或炒干，即成为绞股蓝茶的初制品，再精制整形，包制成袋泡茶形式。

The Plant tissue raise is the plant sterile culture technology, has the totipotency theory according to the vegetable cell, the use plant body exsomatize organ (for example root, stem, leaf, stem point, flower, fruit and so on), the organization (for example cambium, epidermis, cerebral cortex, marrow department cell, endosperm and so on) or the cell (for example big spore, small spore, somatic cell and so on) as well as the protoplast, in aseptic and suitable artificial culture medium and illumination, temperature and so on under artificial condition, can induce injuries the organization, not to decide the bud, the adventitious root, finally forms the complete adult plant the discipline.

植物组织培养即植物无菌培养技术，是根据植物细胞具有全能性的理论，利用植物体离体的器官(如根、茎、叶、茎尖、花、果实等)、组织（如形成层、表皮、皮层、髓部细胞、胚乳等）或细胞（如大孢子、小孢子、体细胞等）以及原生质体，在无菌和适宜的人工培养基及光照、温度等人工条件下，能诱导出愈伤组织、不定芽、不定根，最后形成完整的植株的学科。
