Long noncoding RNAs and miRNAs regulating terpene and tartaric acid biosynthesis in rose‐scented geranium
2019
This study aimed to explore the noncoding RNAs, which have emerged as key regulatory molecules in biological processes, in rose‐scented geranium. We analyzed RNA‐seq data revealing 26 784 long noncoding RNAs (lncRNAs) and 871 miRNAs in rose‐scented geranium. A total of 466 lncRNAs were annotated using different plant lncRNA public databases. Furthermore, 372 lncRNAs and 99 miRNAs were detected that target terpene and tartarate biosynthetic pathways. An interactome, comprising of lncRNAs, miRNAs, and mRNAs, was constructed that represents a noncoding RNA regulatory network of the target mRNAs. Real‐time quantitative PCR expression validation was done for selected lncRNAs involved in the regulation of terpene and tartaric acid pathways. This study provides the first insights into the regulatory functioning of noncoding RNAs in rose‐scented geranium.
