Identification of miRNAs and their target genes in genic male sterility lines in Brassica napus by small RNA sequencing.

ABSTRACT:

Background

Brassica napus is the third leading source of edible oil in the world. Genic male sterility (GMS) lines provide crucial material for harnessing heterosis for rapeseed. GMS lines have been used successfully for rapeseed hybrid production in China. MicroRNAs (miRNAs) play crucial regulatory roles in various plant growth, development, and stress response processes. However, reports on miRNAs that regulate the pollen development of GMS lines in B. napus are few.

Results

In this study, 12 small RNA and transcriptome libraries were constructed and sequenced for the flower buds from the fertile and sterile lines of two recessive GMS (RGMS) lines, namely, "6251AB" and "6284AB". At the same time, 12 small RNA and transcriptome libraries were also constructed and sequenced
