The activity of sod could increase as the longer of storage time no matter the samples covered with vegetable oil or not , kept in light or in dark . in the pcr reaction , a dna fragment with about 550pb length has been amplified by using the genomic dna of s . maltophilia 276 as the temperate , and by using the sequ 根据报道的不同细菌的mnsod基因序列，以5 ’一tacgaygcsctggarccg弓’序列作为上游引物，以5 ’一ccagttcaccacgttcca于3 ’序列作为下游引物，利用pcr反应从及胭1t叩hj1z ’ a276菌株的基因组dna中扩增出一条长度约为550bp的侧a片段。

From this result it can be concluded that the est isoenzyme was very sensitivity for the toxication of hg24 and can be used as a bioindicator of the environmental pollution . the same experiment had been done twice in 2003 . scetion : from october in 2002 to october in 2003 , by using random amplified polymorphic dna ( rapd ) , the effects on ovary ' s dna under different concentration of mercury in freshwater crab ( sinopotamon yangtsekiense ) were detected for the first time 汞对长江华溪蟹卵巢总dna的影响汞对长江华溪蟹( sinopot胭onyangtsekiense )细胞及分子水平的影响以体外暴露的方法，对经汞体外暴露一周长江华溪蟹的卵巢总dna ，采用随机引物扩增多态性dna ( rapd )技术对13条随机引物的扩增图谱用nei共享度公式进行分析。

Those easily found plants and fungi are pinus densiflora , querces mongolica , lespebeza bicolor , rhododendrum chrysanthum , melampyrum roseum , ramaria stricta , cortinarius collinitus , etc , among which , 22 species of plants and 3 species of mushrooms were first reported occurring beside fairy rings of matsutake . 4 . studies on dna polymorphisms of symbiotic edible fungi , tricholoma matsutake . the dna fingerprinting of wild baidiocarps of matsutake , collected from the scenes of major production regions in china , were analyzed based on rapd ( random amplified polymorphic dna ) - pcr patterns were optimized by example experiments of two dna templates in this study 除了常见的赤松(尸inusde胭必ra ) 、蒙古栋( que兀esm口吧口lica ) 、胡枝子(众印‘ bezabicolor ) 、兴安杜鹃( rhododen动侧nc加” anthum )等外，另外以前并未报道的22种植物， 3种高等真菌也在松茸蘑菇圈附近出现频率很高，例如被当地菇农称为松茸花的山萝花( mela州眨”似脚roseum ) ，与松茸同期发生的蘑菇如密丛枝( ramariastricta ) 、粘柄丝膜菌( cortinari 。
