【中文摘要】 本研究以黄伞菌丝cDNA为模板,设计简并引物,经PCR扩增出两条片段SL1和SL2,经过回收、重扩增、克隆与鉴定后进行测序分析,结果发现SL1的序列在Genebank中与三磷酸甘油醛脱氢酶(Glyceraldehyde-3-phosphate dehydrogease,GPD)基因的同源性达到85%,根据SL1序列设计引物,以黄伞菌丝体、原基、菇蕾、子实体菌柄、子实体菌盖的cDNA为模板进行PCR反应以验证其保守性,结果显示此片段在不同分化发育阶段表达量相同。
【英文摘要】 The mixed primer was designed,and two fragments SL1 and SL2 were acquired by PCR templating of the cDNA of Pholiota adiposa(Fr.)quél mycelium.After reamplifying,purifying,cloning,measuring sequence and blasting in GeneBank,the result showed that identified SL1 fragment is similar to Glyceraldehyde-3-phosphate dehydrogease(GPD)gene,and the homology is as high as 85%.The primer is designed on the basis of SL1,cDNA of different period including mycelium,anlage,bud and fruit body(stem and lid of mushroom)was extracted and treated by PCR to verifying the conservativeness.The result shows that the expression quantity of this fragment is uniform during different developing period of Ph adipose.
