Abstract

Abstract:

“Aerial flower and subterranean fruit” is a distinct feature in peanut (Arachis hypogaea L.). To dissect this character at post-transcription level, small RNA sequencing was performed to identify microRNAs in peanut pod shell and seed during eleven developmental stages. Sequencing analysis identified 212 known microRNAs, including 197 conserved and 15 specific microRNA. In addition, 112 novel microRNAs from 62 novel microRNA precursors were identified. Among the known and new microRNAs, 67 microRNAs and their target genes showed differentially expressed patterns during peanut pod development. Expression trend analysis revealed stage-specific and tissue-specific expression of microRNA and their target genes during pod shell and seed development, implying that microRNAs probably played a role in peanut pod development. To validate expression profiles from small RNA sequencing, quantitative real-time RT-PCR were performed using 28 microRNAs and 30 target genes, revealing consistent expression profiles with sequencing results. The data regarding microRNA and their target genes generated in this study would contribute to understanding the molecular mechanism of plant fruit development under darkness and to crop improvement.

Key words: peanut, pod development, small RNA sequencing, microRNA, target gene
