研究人員為了對dek35在籽粒發育過程中的作用有全局性的了解,分別選取了的dek35胚乳以及野生型胚乳進行了RNA轉錄組測序(RNA-Seq服務由伯豪生物提供)。經過數據分析,一共篩選到了4720個差異基因,其中632個基因具有功能注釋。在GO歸類后,研究人員發現,這些基因主要聚集于mitochondrial
inner membrane (GO:0005743, P-value=2.2E-07), ATP synthesis coupled
proton transport (GO:0015986, P-value=0.00043), protein targeting to
mitochondrion (GO:0006626, P-value=2.0E-05) and cytochrome-c oxidase
activity (GO:0004129, P-value=0.0024) (圖8)。
