【摘要】 以草菇(Volvariella volvacea)單孢菌株PYd21(基因組測序菌株)和PYd15(基因組重測序菌株)為材料,配對獲得可正常出菇的異核菌株H15-21??寺y序了PYd21和PYd15的葡萄糖-6-磷酸異構酶基因(gpi),并對基因的結構和表達譜的表達量進行分析。結果表明,PYd21和PYd15的gpi基因序列相同;轉錄組reads定位、paired-end分析結果顯示,gpi基因全長2404bp,ORF全長1659bp,編碼552個氨基酸,含有8個外顯子、7個內(nèi)含子,5’UTR長度為101bp、3’UTR為183bp,RNA加工過程中有2種可變剪切類型、3個可變剪接位點;表達譜測序結果,PYd21、H15-21和PYd15 gpi基因的表達量分別為84.53、1079.31和270.95TPM,草菇gpi基因表達表現(xiàn)出異核體表達協(xié)同增效作用,暗示著異核菌株中的2種不同來源的細胞核可能存在相互作用,這一結果在實時熒光定量PCR檢測后得到證實。
【Abstract】 A hybrid heterokaryon,H15-21,was obtained by mating two single spore isolates,PYd21 and PYd15,the genomes of which were sequenced by de novo sequencing and re-sequencing,respectively.Glucose-6-phosphate isomerase genes(gpi) were cloned and sequenced from both PYd21 and PYd15,and their structures were analyzed through transcriptional read and paired-end mapping.Alignment revealed both sequences to be identical,and that gpi consisted of 2404 bp with an open reading frame(ORF) of 1659 bp encoding a...
