ニハイチュウの比較ゲノミクスから探る小空間スケール適応放散のメカニズム

今年，我继续探索双叶蝇的基因组特征和感觉功能的分子机制。我发现，与其他通常拥有数十个以上GPCR基因的双边动物相比，双叶蝉并没有扩增基因家族，而是大幅减少了GPCR基因家族。神经递质和神经肽的表达表明，根尖细胞可能在周围刺激的信号处理中起重要作用。重复序列占组装的双叶菊基因组的49%。长穿插核元件（long interspersed nuclear element, LINEs）是最丰富的重复家族，占双叶重复序列的30%。基因组学和转录组学分析的所有结果已经总结成一份手稿发表和我的博士论文。

This year, I continued to explore the genomic characteristics and molecular machinery of sensory functions of dicyemid.I found that instead of gene family expansion, dicyemids highly reduce GPCR gene family comparing with other bilaterians which usually possess more than dozens of GPCR genes.The expression of neurotransmitters and neuropeptides suggest that apical cells may play an important role in signal processing for the surrounding stimuli.Repetitive sequences account for 49% of the assembled dicyemid genome. and long interspersed nuclear elements (LINEs) contributing 30% of dicyemid repetitive sequences is the most abundant repeat family.All results of genomic and transcriptomic analyses have been summarized into a manuscript for publication and my PhD thesis.
