We have amplified partial sequences of MADS1, MOC1 (MONOCULM1), and TB1 (teosinte branched 1) genes from 42 bamboo species. Molecular and phylogenetic analyses were performed and the application to bamboo evolution and classification were assessed.
本研究采用PCR扩增的方法从16属42种竹类植物中扩增到了MADS1、MOC1(MONOCULM1)和TB1(teosinte branched1)部分基因序列，并对这些序列进行了详尽的序列分析与分子进化分析，着重探讨了它们在竹类植物系统进化与分类中的应用。
TCP genes, including Teosinte Branched 1(TB1) in maize, Cyclodiea in snapdragon and PCF1 and PCF2 in rice etc., constitute a newly discovered gene family which encode transcription regulators in plants.
摘 要：TCP基因是一类植物中新发现的、可能具有转录因子活性的基因家族，成员包括金鱼草的Cyclodiea、玉米的Teosinte Branched1 (TB1)以及水稻中的PCF1、PCF2等。
The luminescent glass can be used in a radiography image formation system which adopts a high energy X-ray source up to 30 MeV. The spatial resolution is about the same as 301 type luminescent glass excitated by 100 keV X-ray and the spatial resolution may not be less than 1.5 lp/mm when excitated by 12 MeV X-ray. Its luminescence intensity is about 3 times of 301 type. Some effects on its characters of main ingredient materials (BaO, Cs1O, Tb1O_3, Gd1O_3 and Ce1O_3) are also researched in the way of changing the mass fraction and appropriate ingredient configuration for high performance.
并对其性能进行了实验研究，相应的测量结果为：SiO2的质量分数达到50%以上时才能得到玻璃性质较好的材料，并使发光性能得到提高，BaO和Cs2O的质量分数接近相等的条件下，Tb3+离子的质量分数为10.5%时发光性能最好；适量的Gd3+离子可以敏化Tb3+发光，也能增加玻璃密度，而Ce3+离子可以降低发光的余辉；其它的微量元素则主要影响玻璃的熔融温度。
Coli TB1.In experiment ⅱ, according to sequence of porcine defensin pBD-1 gene, We designed a couple of primers with restriction enzyme site Xba ⅰ, and Hind ⅲ by computer.
在实验二中，根据猪防御素pBD-1基因序列，应用计算机软件设计出一对带有酶切位点HindⅢ，XbaⅠ的引物。
DNAs were extracted from R. anatipestifer strain Jb 2, Jb 3, E. coli strain E 4 (from duck) and K 12, and unidentified strain Tb 1 by phenol and chloroform extract method.
采用苯酚－氯仿混合法，提取了鸭疫里氏杆菌（Riemerelaanatipestifer）血清1型Jb2株、Jb3株、未定型菌Tb1株以及鸭大肠杆菌E4株和大肠杆菌K12株的基因组DNA。
Coli TB1 system, and the fusion protein was named MBP - β 2m.
coliTB1原核表达系对Anpl-β2m成熟肽基因进行了可溶性表达，表达的融合蛋白命名为MBP-β2m。
142 patients were studied with Tc - 99m - TB1 in clinical trial ⅱ (normal 22 and heart disease 120).
心肌显象剂~（99m）Tc-TBIⅡ期临床试验共观察了正常人22例和各类心脏病患者120例。
Results: The brain water and sodium contents of group T and WB were significantly higher than that of group TB1 and S in the first day after trauma (P0.01).
结果：脑外伤后第1天，T组与WB组脑含水量和脑组织钠含量较其他两组明显增高；
In maize, tb1 has a relatively high expression level in axillary meristems and stamens of ear primordial thus suppress the development of corresponding organs.
在玉米中，tb1基因在腋分生组织和雄蕊原基中相对大刍草有较高的表达，从而抑制了对应组织的生长发育，造成玉米和大刍草的形态差异。
TB1 controls the apical dominance in maize and is involved in the maize tiller development.
