Global identification and analysis revealed differentially expressed lncRNAs associated with meiosis and low fertility in autotetraploid rice.

The differential expression levels of lncRNAs, associated with transposable elements and meiosis-regulated targets, might be endogenous noncoding regulators of pollen/embryo sac development that cause low fertility in autotetraploid rice. The results enhance our understanding about rice lncRNAs, and facilitate functional research in autotetraploid rice.
