Development-associated microRNAs in grains of wheat (Triticum aestivum L.).

ABSTRACT:

Background

MicroRNAs (miRNAs) are a class of regulatory small RNAs (sRNAs) that down-regulate target genes by mRNA degradation or translational repression. Numerous plant miRNAs have been identified. Evidence is increasing for their crucial roles during plant development. In the globally important crop of wheat (Triticum aestivum L.), the process by which grains are formed determines yield and end-use quality. However, little is known about miRNA-mediated developmental regulation of grain production. Here, we applied high-throughput sRNA sequencing and genome-wide mining to identify miRNAs potentially involved in the developmental regulation of wheat grains.

Results

Four sRNA libraries were generated and sequenced from developing grains sampled at 5, 15, 25, and 30 days afte
