Motif analysis and sequence alignment
The motif analysis for promoters was performed with PlantRegMap(Tianet al. , 2020). The promoter sequences ofPik* (Zhai et al. , 2011), Pi1 (Huaet al. , 2012), Pi7 (Campbell, Chen and Ronald, 2004),Pikh (Zhai et al. , 2014), Pikm (Ashikawa et
al. , 2008), and Pikp (ZdrzaĆek et al. , 2020a) were
collected as reported. Sequence alignment was performed with
MAFFT(Rozewicki et al. , 2019) and was visualized with ESPript
3(Robert and Gouet, 2014).
