Genome-Wide Analysis of Long Non-coding RNAs Involved in Nodule Senescence in Medicago truncatula.

ABSTRACT: Plant long non-coding RNAs (lncRNAs) are widely accepted to play crucial roles during diverse biological processes. In recent years, thousands of lncRNAs related to the establishment of symbiosis, root nodule organogenesis and nodule development have been identified in legumes. However, lncRNAs involved in nodule senescence have not been reported. In this study, senescence-related lncRNAs were investigated in Medicago truncatula nodules by high-throughput strand-specific RNA-seq. A total of 4576 lncRNAs and 126 differentially expressed lncRNAs (DElncRNAs) were identified. We found that more than 60% lncRNAs were associated with transposable elements, especially TIR/Mutator and Helitron DNA transposons families. In addition, 49 DElncRNAs were predicted to be the targets of micro RNAs
