With many years of research, two inbreeds 18-599 and 18-599 are sieved to be excellent on both characters of induction efficiency and number of regenerating. They also act much better comparing with those superior acceptors as B73, A188 and zong 31, which are known in foreign and home country, and their induction efficiency don't act different essentially, however their number of regenerating is much lower.

6经过多年的重复研究后筛选到的玉米幼胚培养胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数等2个幼胚培养能力性状均表现十分优良的自交系18-599和18-599，与国内外公认的玉米转基因优良受体，如B73、A188和综31、中自03等相比较，它们不仅在幼胚培养胚性愈伤组织诱导率表现上没有实质性的差别，而且在胚性愈伤组织绿苗发生数的表现上要比后者优良得多。

According to Griffing's method 1, diallel crossing was built and CA was analyzed. Variance analysis showed that there were the greatly significant difference among the both of GCA in inbreeds and SCA in crosses, respectively. The high GCA of 18-599 and 18-599 and the low SCA variance of their crosses showed the strong and stable heredity on the both characters. Taking them as parents, the generations with high and stable induction and regeneration will be gotten.

ABSTRACT It is because that the excellent acceptors for maize transgenic engineering are insufficient in our country, especially in the southwest mountain areas of china and hereditary variation regularity for the two characters such as efficiency of embryonic callus induction and number of regenerating plant (these two characters were abbreviated to the nduction efficiency and number of regenerating in the following of the paper, respectively), which hint the maize culturing capacity, is not very clear. Therefore, aiming at picking out superior acceptors, we had made systematic researches on the two characters with combing traditional quantitative-character genetic analyzing methods such as single-factor genetic mating design, diallel crossing genetic design, genetic effect analyzing method and the modern molecular locating method such as QTLs'. The main results are followed.(1) 50 superior inbred lines and about 30 crosses in our country, especially in the southwest of China were used for identifying and selecting the superior genotypes in the above two investigated characters under the same culturing condition in 2000 and 2001. There was very significant difference among the genotypes in the both characters. But the two characters were not certainly related. Some genotypes such as 18-599 and 18-599 were very good in them. For some ones such as zong 31, induction was higher than 18-599 and 18-599 in the efficiency, but it was only 1/3 to the later in regenerating number. In some genotypes such as S37, R08, R15, P138, A318, induction efficiency was just about 3% and scarcely any regenerating plants were got. On the whole, hybrids acted better than inbreeds in the both characters.(2) Two kind of inbreeds were selected as parents of the Griffing's method 1. 18-599 and 18-599 and the inbred line zong 31 are one kind because they are not only superior in the characters of maize cross breeding, such as CA, resistance to disease and the important agricultural characters, but also excellent in transformation characters as the induction and regeneration.

针对我国、特别是西南山地所需玉米转基因工程育种优良受体极为匮乏和反应玉米幼胚培养能力的2个主要性状，即玉米幼胚胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数的遗传变异规律十分不清楚的实际情况，本研究从筛选玉米转基因工程所需要的优良受体入手，采用单因素遗传交配设计、双列杂交遗传交配设计、世代基因效应等传统数量性状分析方法，以及现代分子标记定位主效QTL分析方法，对玉米幼胚胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数等2个性状进行了较为系统的分析研究，取得以下主要研究结果：(1)于2000年和2001年通过对我国、特别是西南地区近50份优良自交系和近30个杂交组合，在相同培养条件下，对幼胚培养胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数等2个幼胚培养能力性状进行了筛选与鉴定，发现玉米不同基因型具有完全不同的幼胚培养胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数，但幼胚培养胚性愈伤组织诱导率与胚性愈伤组织绿苗发生数并不具有必然的相关关系，有的基因型，如自交系18-599和18-599在胚性愈伤组织诱导率和愈伤组织绿苗发生数等2个性状都表现相当优异；有的基因型，如自交系综31，仅幼胚培养胚性愈伤组织诱导率性状表现高于19-599和18-599，但在胚性愈伤组织绿苗发生数这一性状则与它们有相当大的差距，仅为19-599和18-599的1/3左右；有的基因型，如S37、R08、R15、P138、A318等玉米自交系不仅幼胚培养胚性愈伤组织诱导率很低，平均仅在3％左右，而且胚性愈伤组织绿苗发生数表现也很差，基本上没有分化成苗。

Indeed, all my freinds and family are not affected at all, but we are the whole, I cannot escape from other's painful, sorrow, and tears, especially when I face the growing death number day and day, till an unbelievable number: more than 50,000 finally estimated.

Here, we demonstrated in this work that CsrA performs a negative regulator of the cel expression. cel, encoding lysis protein (LysE7), is located downstream of the colicin E7 structural gene in the ColE7 operon. Lysis protein was essential for colicin release and causes a decline in culture turbidity as well as lethality of the host cell when overproduced. Western blotting analysis of the level of LysE7 in the wild-type and csrA mutant strains was examined.

在本论文中，我们进一步发现到CsrA对於cel 基因的表现具有抑制的现象。cel 基因位在质体ColE7-K317上的E7大肠杆菌操纵子，可以制造出溶菌蛋白质(lysis protein， LysE7)，协助大肠杆菌素及免疫蛋白质的复合体运送至菌体外；但当菌体产生过多的溶菌蛋白质，则会导致宿主细胞的死亡，所以溶菌蛋白质的表现必须受到严密的调控，避免菌体产生过量，而CsrA则是目前第一个被发现到能调控溶菌蛋白质表现的因子。

After a period of initial great shape, we are going a little bad in terms of results, but the game is always our strength and I am sure that after a bit of appanamento back in points and we will do out of this negative trends, which, I repeat, in reality we only penalizes the point of view of the results.

Result:①out of 25 patients,17 exhibited myeloma-related bone lesions on radionuclide imaging,the positive rate was 68.0%,ribs and spine were involved most frequently,162 lesions showed high uptake of radionuclide,the lesions lied in ribs appeared as strings of pearls,and those in sternums and vertebrae showed linear high uptake,the other 4 showed decreased radionuclide uptake.②the positive rate on radiography was 68.0%(17/25),which was the same as that on radionuclide imaging,the patterns were osteoporosis,pathological fracture,osteolysis or two or two and above of these appearances, radiography detected more abnormalities than radionuclide imaging in identical sites(162 versus 144),but radionuclide imaging detected more lesions than radiography in ribs and sternums.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
