Network of degradome validated miRNA-target pairs associated with P. brassicae response in B. napus. Red rectangles represent the miRNAs and blue rectangles represent the target transcripts validated by degradome sequencing. Italics indicate miRNAs that are significantly differentially expressed after P. brassicae infection. AFB, auxin signaling F-box; AGO1, argonaute1; AP2, apetala2; APS, ATP sulfurylase; ARF, auxin response factor; MYB, myeloblastosis; NFYA, nuclear transcription factor Y subunit alpha; AGL, agamous-like MADS-box protein; AL7, PHD finger protein ALFIN-LIKE 7-like; BAG1. BAG family molecular chaperone regulator 1-like; CAC3, acetyl-coenzyme A carboxylase carboxyl transferase subunit alpha; DCL1, endoribonuclease Dicer homolog 1; DREB, dehydration-responsive element-binding protein 2B-like; FBX6, F-box only protein 6; GRF, growth-regulating factor; HSP90, heat shock protein 90-2-like; PNSL2, photosynthetic NDH subunit of lumenal location 2, chloroplastic-like; PPR, pentatricopeptide repeat-containing protein; SCL, scarecrow-like protein; SPL, quamosa promoter-binding-like protein; TIR1, transport inhibitor response 1.
