Integrative analysis of small RNA and degradome sequencing reveals the role of miRNAs in monoterpene biosynthesis in linalool-type Cinnamomum camphora.

ABSTRACT:

Background

Cinnamomum camphora is a valuable aromatic oil-producing species with significant economic and industrial importance. Linalool, a monoterpenoid compound and a major component of camphor leaf essential oil, is widely used in cosmetics, food, and pharmaceuticals. While microRNAs (miRNAs) are known to regulate terpenoid biosynthesis, their regulatory role in linalool biosynthesis remains largely unexplored.

Results

In this study, we performed small RNA and degradome sequencing on three C. camphora samples (H_MAR, H_MAY, and L_MAY) exhibiting significant differences in linalool content. A total of 199 known and 200 novel miRNAs were identified. Among them, 170 differentially expressed miRNAs (DEMs; 83 downregulated and 87 upregulated) were detected between H_MAY and H
