The results confirmed previous report that IBV can synthesize sgRNA via template switch mediated by a noncanonical core sequence (Bentley et al., 2013) Notably, the mutant virus carrying four mutations (A27100U/A27111U/G27113C/G27114C) was also unable to produce ncRNA (Fig. 4) , suggesting these nucleotides are required for ncRNA production.	./cache/cord-309469-2naxn580.txt	./txt/cord-309469-2naxn580.txt
