研究方向
非編碼RNA與植物生殖發育
非編碼RNA基於其種類繁多、數量巨大、功能多樣等特征而被譽為生命科學研究中的“暗物質”。我們以擬南芥和入侵植物為研究對象,探索不同種類的非編碼RNA,主要關注小RNA、套索RNA、轉座子RNA,如何產生、如何發揮作用以及在植物生殖細胞命運決定和環境可塑性發育中發揮何種作用。我們近年的研究成果揭示了小RNA產生和效應複合體新的轉錄後調控機製、揭示了植物精細胞攜帶的特定非編碼RNA促進種子早期細胞分裂、開發了RNA剪切反應中內含子形成的套索RNA的鑒定方法和功能研究體係、開辟了內含子套索RNA代謝調控和功能研究的新方向。在Dev Cell, PNAS, Plant Cell, PLoS Genet, Nat Commun, New Phytol等期刊以通訊作者身份發表多篇研究論文。目前實驗室的研究工作主要集中於套索RNA和轉座子RNA的代謝調控和生物學功能。
RNA biology in plants
Non-coding RNAs ubiquitously exist in plants and animals, which are involved various biological processes at the transcriptional and posttranscriptional levels. Our research uses Arabidopsis as the model system and focuses on non-coding RNAs, especially small RNA, lariat RNAs, TE RNA. We have been focused on how plant cells produce non-coding RNAs, how non-coding RNAs act in gene silencing, and what the biological consequences of non-coding RNAs during plant gametogenesis and early seed development. In my opinion, the most striking finding in my lab is that by developing a systemic method to identify lariat RNAs, traditionally as the “by-products” of RNA splicing, we demonstrate that lariat RNAs can be selectively retained to regulate various biological processes in a spatiotemporally regulated manner. Another interesting finding in my lab is that sperm-delivered miRNA triggers the first endosperm nuclear division event. Future work will focus on the mechanism of lariat RNA turnover, biological significance of lariat RNA accumulation, and roles of non-coding RNA-mediated epigenetic regulation in gamete cell fate determination and genome integrity in plants. We hope that studies in my lab about these fundamental mechanisms in plant epigenetics will help people understanding species biodiversity and evolution.
