Abstract

The soldier caste is one of the most distinguished castes inside the termite colony. The mechanism of soldier caste differentiation has mainly been studied at the transcriptional level, but the function of microRNAs (miRNAs) in soldier caste differentiation is seldom studied. In this study, the workers of Shiraki were treated with methoprene, a juvenile hormone analog which can induce workers to transform into soldiers. The miRNomes of the methoprene-treated workers and the controls were sequenced. Then, the differentially expressed miRNAs (DEmiRs) were corrected with the differentially expressed genes DEGs to construct the DEmiR-DEG regulatory network. Afterwards, the DEmiR-regulated DEGs were subjected to GO enrichment and KEGG enrichment analysis. A total of 1,324 miRNAs were identified, among which 116 miRNAs were screened as DEmiRs between the methoprene-treated group and the control group. A total of 4,433 DEmiR-DEG pairs were obtained. No GO term was recognized as significant in the cellular component, molecular function, or biological process categories. The KEGG enrichment analysis of the DEmiR-regulated DEGs showed that the ribosome biogenesis in eukaryotes and circadian rhythm-fly pathways were enriched. This study demonstrates that DEmiRs and DEGs form a complex network regulating soldier caste differentiation in termites.

摘要

兵蚁品级是白蚁群体中最显著的品级之一。兵蚁品级分化的机制主要在转录水平上进行了研究，但微小RNA（miRNA）在兵蚁品级分化中的作用鲜有研究。在本研究中，用烯虫酯（一种能诱导工蚁转变为兵蚁的保幼激素类似物）处理了白木白蚁的工蚁。对经烯虫酯处理的工蚁和对照的miRNA组进行了测序。然后，将差异表达的miRNA（DEmiR）与差异表达基因（DEG）进行校正，以构建DEmiR-DEG调控网络。之后，对DEmiR调控的DEG进行基因本体（GO）富集分析和京都基因与基因组百科全书（KEGG）富集分析。共鉴定出1324个miRNA，其中116个miRNA被筛选为烯虫酯处理组和对照组之间的DEmiR。共获得4433对DEmiR-DEG。在细胞成分、分子功能或生物学过程类别中，没有GO术语被认为具有显著性。对DEmiR调控的DEG的KEGG富集分析表明，真核生物中的核糖体生物合成和昼夜节律-果蝇途径得到了富集。本研究表明，DEmiR和DEG形成了一个复杂的网络，调控白蚁的兵蚁品级分化。
