Identification of lncRNAs involved in rice ovule development and female gametophyte abortion by genome-wide screening and functional analysis.

ABSTRACT:

Background

As important female reproductive tissues, the rice (Oryza sativa L.) ovule and female gametophyte is significant in terms of their fertility. Long noncoding RNAs (lncRNAs) play important and wide-ranging roles in the growth and development of plants and have become a major research focus in recent years. Therefore, we explored the characterization and expression change of lncRNAs during ovule development and female gametophytic abortion.

Results

In our study, whole-transcriptome strand-specific RNA sequencing (ssRNA-seq) was performed in the ovules of a high-frequency female-sterile rice line (fsv1) and a wild-type rice line (Gui99) at the megaspore mother cell meiosis stage (stage 1), functional megaspore mitosis stage (stage 2) and female gametophyte mature stag
