  1. It was suggested that eric - pcr could substitute for rapd in research related to the genetic identification and genetic diversity in auricularia and other edible and medicinal fungi : 2 to a certain extent, genetic differences among auricularia strains tested in this study did not have necessary relativity with their geographical origins respectively ; 3 in this study, genetic diversity in a. polytricha was higher than that in a. auricula : 4 in this study, a. fuscosuccinea had a higher homology to a. auricula than to a. polytricha ; 5 morphological characteristics validated the results from eric - pcr and provided a potential explanation for the higher similarity coefficient between a. auricular and a. fuscosuccinea ; 6 southern hybridization was employed by choosing a strain from a. auricula as a probe which hybridized with a. auricula and a. fuscosuccinea except a. polytricha, further confirming the veracity of the results from eric - pcr ; 7 in this study, isozyme analysis could not cluster the 7 strains from three auricularia species to different groups efficiently ; 8 2 strains from two auricularia species revealed high conservative degree and the restriction fragment patterns by 4 kinds of restricted enzymes showed no diversity

    本研究中，木耳屬2個種的2個菌株在its區域表現出較高的保守性， 4種限制型內切酶的酶切圖譜沒有顯示出多態性；增加內切酶種類及供試菌株數量，有可能獲得具有多態性的限制性內切酶酶切圖譜； 9本實驗中， its區域的真菌特異性引物與真核生物通用引物對于擴增效果無較大差異，擴增片段長度均為650bp左右； 10根據形態學實驗、 eric - pcr實驗以及southern雜交實驗的結果分析，紫木木耳屬種質資源的遺傳鑒定和遺傳多樣性評價耳極有可能是毛木耳種的一個變種; n .本研究中所用的gutc法是一種適用於木耳屬菌株基因組洲a快速提取的方法; 12 .傳統的形態學分類法和現代的分子生物學分類法，兩者的關系是相輔相成，互為驗證
  2. Carrot tissue culture and plant regeneration factors including explants, medium and culture condition are combined together to study the most efficient protocol of carrot tissue culture and plant regeneration thereof. the most suitable explant is fresh hypocotyls segment and precultured hypocotyls derived from 7 - 10 day old aseptic plantlets generating in dark or in dim light, the best recipe for cullus induction and subculture is b5c ( 85 with 0. 5mg / l 6ba and 0. 5mg / l 2, 4 - d ), the ideal recipe for plant regeneration is 65 or ms free of hormone. a phytotron with a 16 / 8 h day / night cycle, at 25 is feasible for plant regeneration, and occasional exposure to sun light dramatically stimulates plant growth

    4 .研究了無機鹽和碳氮源對青黴pt95菌株菌核生物量和類胡蘿卜素產率的影響作用，結果表明:供試的4種無機鹽中， kzhpo ;的單因子效應最好; kzhpo4 + kci + mgs04表現出最好的正協同效應。
  4. When both genes were co - expressed in e. coli, the activity of ppsa varied from 2. 1 - 9. 1 fold comparing to control, but the activity of tkta was relatively stable ( 3. 9 - 4. 5 fold ). whatever the two genes were expressed respectively or cooperatively, both could promote the production of dahp, the first intermediate of the common aromatic pathway, but co - expression was more effective on forming dahp and screened ppt - and ptp - as more effective. the results demonstrate that co - expression of ppsa and tkta can improve the production of dahp, and what ' s more, when multigenes co - expressed, the recombinant which has coordinated enzymes activity is optimum
