摘要：Circular RNAs (circRNAs) are covalently closed RNA molecules, and have been identifiedin many crops. However, there are few datasets for circRNA junctions from common wheat duringFusarium head blight disease. In the present study, we used RNA-seq to determine the changes incircRNAs among the control (CK) and 1, 3, and 5 days post-Fusarium graminearum inoculation (dpi)samples. More than one billion reads were produced from 12 libraries, and 99.99% of the readswere successfully mapped to a wheat reference genome. In total, 2091 high-confidence circRNAs—which had two or more junction reads and were supported by at least two circRNA identificationalgorithms—were detected. The completed expression profiling revealed a distinct expression patternof circRNAs among the CK, 1dpi, 3dpi and 5dpi samples. This study provides a valuable resourcefor identifying F. graminearum infection-responsive circRNAs in wheat and for further functionalcharacterization of circRNAs that participated in the Fusarium head blight disease response of wheat.
