  1. The characteristics of tm - 22 expression presented in transgenic tobacco : 1 ). virus specificity in either homozygote or heterozygote ; 2 ) tm - 22 gene integrated in tobacco genomic dna with single copy and in inheritance and segregation to progenies on the mendel role ; 3 ). transgenic line with tm - 22 promoter ( ptm47 ) showed infected symptoms with cell death distinguished to one with 35s promoter ( ptm49 ) after inoculation with tomv - 2a

    其次，通過氨基酸序列和結構的比較，確定tm - 2 ~ 2基因的編碼蛋白與tomv病毒在抗病反應中相互識別的特異氨基酸及其功能；然後，應用重組dna技術，互換tm - 2 ~ 2基因和tm - 2基因的對應結構域，構建嵌合基因，獲得嵌合蛋白表達的轉化體，驗證tm - 2 ~ 2編碼蛋白中變異氨基酸的作用。
  2. Heredity modes of 6 traits were studied by analysis of population genetics, by the method of family combination analysis, by the methods of proband ' s sib analysis, segregation analysis, the threshold model of polygenes, and analysis of typical family trees, according to the data of the 72 families. the relative importance between genetic and environmental effect on each character was evaluated by comparing the coherence of twins. gene frequencies of 5 genetic characters, calculated from han group in huhhot, were compared with other groups by u - test so as to study the population or nationality difference in heredity

    採用群體遺傳學分析、家系組合分析法、先證者同胞法、分離分析法及多基因閾值模式分析方法對所得家系資料進行了統計學分析，結合家繫系譜分析探討了上述6項特徵的遺傳方式；通過雙生子一致率的比較，對上述特徵的遺傳與環境效應的相對重要性進行了評價；計算了呼和浩特市漢族群體5對遺傳性狀的基因頻率，採用u檢驗方法與相關文獻報道的其他群體進行了比較，探討了不同種族間或民族間的遺傳差異性。
  3. Methods : ( 1 ) the segregation of foreign target gene in the t1 by histochmical gus assays ; ( 2 ) identification of pure line from transgenic tomatoes ( tl ) through examining gus expression in pollens in conjunction with pcr analysis of marker gene ( npt ) ; ( 3 ) the transcript levels of leetrl or leetr2 in anti - sense transgenic plants ; ( 4 ) the phenotypes of the transgenic plants in tomato during whole life cycle under ethylene - treated and non - treated conditions

    本研究以反義乙烯受體leetr1 ， leetr2基因番茄t _ 0代種子為實驗材料，利用gus基因表達研究外源基因的遺傳規律，並藉助于pcr技術對目的和標記基因的鑒定獲得轉基因t _ 1代材料。利用gus基因在t1花粉中的表達鑒定獲得轉基因純合植株。研究了轉基因後代的生長發育模式、對外源乙烯敏感性，以及靶基因的表達特性，初步探明了它們在乙烯受體系統中的功能。
  4. These results demonstrated that merely examining the segregation of reporter gene in pollens is a reliable method that could avoid the laborious testing process of the pure line from transformed plants ; ( 3 ) the transcript levels of leetrl and leetrl were checked by northern blotting analysis

    （ 3 ）兩個基因在反義植株里的表達都受到不同程度的抑制。在反義leetr1植株里， leetr1表達被抑制后， leetr2的表達也受到不同程度的抑制。同時，反義leetr2植株里也有相似的結果。
  5. Segregation the separation of the two alleles of a gene into different gametes, brought about by the separation of homologous chromosomes at anaphase 1 of meiosis

    分離：同源染色體在細胞減數分裂後期中向細胞極遷移，使等位基因最終分向不同配子。
  6. Results showed that : ( 1 ) in general, the segregation ratios of target gene in some tl lines are conformed to 3 : 1, however, some are not possibly due to gene silence or missing in the self - pollinated progeny ; ( 2 ) two homozygous plants were identified from 10 putative transgenic plants

    主要結果如下： （ 1 ）我們對外源基因在番茄體內的遺傳規律研究表明，在大多數情況下，單拷貝插入外源基因將導致轉基因後代按孟德爾單顯性基因3 1規律分離，但是部分轉化系比例偏低，可能發生了基因丟失或者沉默。
  7. Then, we transformed those two genes into tomato and tobacco plants via agrobacterium tumefaciens. after verified by antibiotic resistance, reporter gene examination, southern blot detection, and genetic segregation analysis, we obtained 3 and 7 transgenic tobacco plants with one copy of rbcs 3a - gus or rbcs 3c - gus gene, respectively. further, we established two suspension - cultured cell lines using above mentioned two kinds of transgenic tobacco plants

    對得到的再生煙草植株分別進行了報告基因表達水平檢測、 southern - blot鑒定以及t _ 0代轉基因種子遺傳分離規律分析，分別得到了單拷貝的穩定表達番茄rbcs3a - gusa 、 rbcs3c - gusa和35s - gusa基因的轉基因煙草3株、 7株和1株，同時還得到單拷貝的只轉化gusa基因的陰性對照轉基因煙草3株。
  8. The segregation ratio of wild type plants to mutant plants in the population degenerated from heterozygotes was 3 : 1, indicating that the mutant is controlled by a single recessive gene, and designated tentatively as tor

    同時，雜合株系呈典型的3 : 1分離比例，表明該突變性狀由單隱性基因控制，並將該突變體暫時命名為tor 。
