摘要
MicroRNA是一类20-24 nt核苷酸长度的参与基因转录后水平调控的非编码小分子RNA。利用高通量测序技术获得鳜(Siniperca chuatsi)孵化后第3天、第17天和第28天全鱼miRNA转录组,共鉴定出1 084个miRNAs,其中432个已知、624个保守、28个新发现。第17天时鉴定出的miRNA个数最多,为926个。在3个发育时期都表达的有628个miRNAs,只在各时期中特异表达的分别有71、104和70个miRNAs。一些与鳜发育相关的miRNAs在上述3个时期呈现持续上调或下调的表达特点。进一步的实验表明,miR-199-5p和miR-203可能与鳜生长发育相关,相应的靶基因分别是WnT和MyoD。
MicroRNA(miRNA)is a kind of non-coding small RNA molecules with the length of about 20-22 nt,and they are involved in regulating the expression of target genes at the post-transcriptional level.High-throughput sequencing technology was employed to analyze the miRNA transcriptome of the whole larvae of Siniperca chuatsi at day3,day17 and day28 after hatching.A total of1084 miRNAs were identified,including 432 known,624 conserved,and 28 new miRNAs.miRNAs of the 17-day larvae were identified the most with 926.The 628 miRNAs were ubiquitously expressed at all the days sampled,while 71,104 and 70 miRNAs were specially expressed at day3,day17 and day28,respectively.Several miRNAs that were involved in development showed sustained up or down regulation patterns.Further results suggested that miR-199-5 p/miR-203 were correlated with the growth and development of mandarin fish,and the corresponding target genes were WnT and MyoD,respectively.
