Alternative splicing events in T. rubrum. a Schematic chart illustrating the formation of three circRNAs, Tru_circ00222_001, Tru_circ00222_002 and Tru_circ00222_004. These three circRNAs are generated by alternative splicing from the same host gene: TERG_00222. b Four types of AS events identified in the conidial and mycelial stages. A3SS: alternative 3′ splice site; A5SS: alternative 5′ splice site; IR: intron retained; ES: exon skipping
