【摘要】 根據(jù)草菇(Volvariella volvacea)S-腺苷-L-高半胱氨酸水解酶基因(SAHH)全長cDNA序列設(shè)計引物,以草菇基因組DNA為模板,PCR擴(kuò)增獲得草菇SAHH基因的全長序列,序列分析結(jié)果表明,草菇SAHH長度為1868bp,編碼430個氨基酸殘基,基因由12個外顯子和11個內(nèi)含子組成,將草菇SAHH基因推斷的氨基酸序列與其它物種的SAHH基因氨基酸序列進(jìn)行比較發(fā)現(xiàn),SAHH基因保守性較高。

【Abstract】 The genomic sequence of a S-adenosyl-L-homocysteine hydrolase gene (SAHH) from Volvariella volvacea was amplified using specific primers designed according to the full-length SAHH cDNA. SAHH consists of 1 868 bp encoding 430 amino acids,and contains 12 exons and 11 introns. A phylogenetic tree constructed on the basis of the amino acid sequences of SAHH genes in V. volvacea and other reference species revealed a high degree of conservation.
