MicroRNA expression in multistage date fruit development

Abstract

MicroRNAs (miRNAs) are small endogenous noncoding RNAs. Plant miRNAs are known to play important regulatory roles in homeostasis, stress response, and diverse developmental processes. Here, we describe the identification of conserved miRNAs in date palm (Phoenix dactylifera L.) based on transcriptomic data acquired across multistage fruit development and genome sequences, which include 238 plant conserved miRNAs and 276 novel P. dactylifera-specific miRNAs.
