Molecular mechanism of RNA metabolism in regulating gene expression in plant development.



a. Functional analysis of DEAD-box proteins in plants

RNA(包括mRNA、rRNA與tRNA)分子一直扮演著重要的角色,正確的RNA分子及它們所形成特定的二級與三級結構,影響著後續特定基因的正常表現,與它們所扮演的生理功能。RNA helicases是細胞內負責維持與重組正確RNA分子結構的主要酵素,它能解開雙股RNA,重組RNA結構,進而影響RNA的功能。DEAD box RNA helicases是RNA helicases家族中成員最大的一族,它幾乎參與了所有和RNA分子有關的一些細胞生理過程,包括transcription、nuclear RNA splicing、RNAtransport、RNA turnover、RNAi、RNA editing、translation initiation與 ribosome biogenesis。雖然DEAD box RNA helicases參與這些不同的細胞生理過程,但是它們的確切的功能與調控方式仍需要進一步釐清。目前普遍使用酵母菌來研究DEAD box RNA helicases,但是植物(以水稻與阿拉伯芥為例)屬於高等多細胞真核生物有著不同的特化細胞,這些細胞必須協調運作以維持完整生命週期。因此,只以單細胞酵母菌的研究來推測DEAD box RNA helicases在植物體中的角色常常不能呈現它完整的面貌。為了瞭解植物DEAD box RNA helicases的真正功能、調控方式與影響層面,我們探討對植物中不同DEAD box RNA helicase的功能。首先我們已經對植物中DEAD box RNA helicases-36 (RH36)的初步研究成果,並逐步解開它在植物中的所扮演的角色,我們的結果已經確定RH36 功能與植物雌配子體有關。


b. Poly(A) tail and gene expression in plant

基因表現的調控機制可分為轉錄階層 (transcriptional level) 和後轉錄階層 (post-transcriptional) 兩種形式;然而人們對於基因表現在轉錄階層的調控機制較為熟悉,對於後轉錄階層的調控則較為陌生。在真核生物中,mRNA的降解過程是poly(A) tail先被分解,接著才進行5’ decapping和5’ exonuclease催化的5'到3'方向的mRNA分解,或不經由5’decapping而是直接進行3' exonuclease催化的3’到5’方向的mRNA分解,而poly(A) tail的分解是絕大部分mRNA降解的速率決定步驟。從酵母菌的研究中得知,CAF1 (CCR4 associated factor 1) 能與CCR4 (carbohydrate catabolism repression 4) 結合並參與mRNA的代謝。目前已經知道CAF1與CCR4這兩個蛋白質具有deadenylase的功能,所以一般相信它們直接參與了mRNA的分解,然而我們並不了解CAF1與CCR4基因在植物系統中是否具有相同的功能。我們選擇單子葉模式植物-水稻為基礎來分析CAF1與CCR4的功能。我們分離出水稻的CAF1與CCR4基因,然後分析基因的表現,釐清水稻中各別CAF1與CCR4基因在不同組織或器官中的表現模式。我們發現其中OsCAF1A表現在Leaves、Shoots、Sheaths與Panicles,而OsCAF1B表現在Roots、Leaves、Nodes、Senesces leaves與Panicles;另外,OsCAF1A是受糖抑制表現的基因,而OsCAF1B為受糖誘導表現的基因。此外利用E.Coli表現系統將OsCAF1AOsCAF1B重組蛋白大量的表達出來,並確定其都具deadenylase的功能。最後我們也已經構築完成OsCAF1AOsCAF1B over-expression 及RNAi的表達載體,並使用基因轉殖方法將OsCAF1AOsCAF1B在水稻中大量表現,另一方面進行RNAi抑制水稻內生OsCAF1基因的表現,希望藉由這些水稻轉殖植株,可以進一步了解CAF1基因在水稻中所扮演的角色。
