Transcript models of host genes from which intronic miRNAs were derived. (A) Bra-MIR838 from the 11^th intron of Bra033293. (B) Bra-MIR5712 from the 5^th intron of Bra013582. (C) Bra-MIR5725 from the sole intron of Bra034911. Blue rectangles indicate the original coding sequence models without untranslated regions; red rectangles indicate Brassica rapa ssp. pekinensis cv. Bre seedling; orange rectangles indicate B. rapa ssp. chinensis cv. Wut seedling; green rectangles indicate cv. Bre inflorescence apex; pink rectangles indicate cv. Wut inflorescence apex.
