中华蜜蜂精巢和卵巢差异表达基因分析

Analysis of differentially expressed genes in testes and ovaries of Apis cerana cerana(Hymenoptera:Apidae)

【目的】在蜂群中,雄蜂与蜂王都有着发育完全的性腺,但两者达到性成熟的时间却是不同步的。本研究旨在探究中华蜜蜂Apis cerana cerana雄蜂与蜂王生殖腺的基因表达差异。【方法】利用Illumina测序技术对中华蜜蜂雄蜂精巢与蜂王卵巢转录组差异表达基因(differentially expressed genes,DEGs)进行分析。【结果】从中华蜜蜂精巢与卵巢中共鉴定出5312个差异表达基因,其中2668个基因在精巢中表达上调,2644个基因在卵巢中表达上调。并鉴定了11个与性别决定和精子卵子发生相关的候选基因。这些差异表达基因可以归类到1458个GO功能类别和132个KEGG通路,其中,有4个GO条目和2个KEGG通路显著富集。【结论】这些结果为研究中华蜜蜂繁殖的分子机制提供了有价值的基因表达信息。

【Aim】In honeybee colonies,both drones and queens have fully developed gonads,but they do not reach sexual maturity at the same time.The aim of this study is to explore the gene expression difference of gonads between drones and queens of the Asian honey bee,Apis cerana cerana.【Methods】Illumina sequencing technology was used to analyze the differentially expressed genes(DEGs)in the transcriptome between testis of drone and ovary of queen of A.cerana cerana.【Results】We identified 5312 DEGs between testis and ovary of A.cerana cerana,among which 2668 and 2644 genes were up-regulated in testis and ovary,respectively.We also identified 11 candidate genes related to sex determination,spermatogenesis and oogenesis.These DEGs could be classified into 1458 GO functional classes and 132 KEGG pathways with four GO entries and two KEGG pathways significantly enriched.【Conclusion】These results provide valuable gene expression information for the study of the molecular mechanism of reproduction in A.cerana cerana.
