MAFFT version 7 (https://mafft.cbrc.jp/alignment/server/ (accessed on 8 December 2021)) was used to perform multi-sequence alignment on the TKS WRKY protein sequence domain with G-INS-1 (progressive method with an accurate guide tree) settings. The phylogenetic tree was constructed by MEGA software (version 7.0, Mega Limited, Auckland, New Zealand) with the neighbor-joining (NJ) method based on the comparison between TKS and Arabidopsis proteins; then we used Illustrator software (version 2019, Adobe, San Jose, CA, USA) to beautify and add color. The sequences of the WRKY protein from Arabidopsis, maize [50 (link)], rice [61 (link),67 (link)], grape [47 (link)], Brachypodium distachyon [68 (link)], pineapple [64 (link)], peach [69 ], and poplar [36 (link)] were obtained according to the corresponding literature and instructions downloaded from the Phytozome databases (https://phytozome.jgi.doe.gov/ (accessed on 27 December 2021)).
