Amino acid sequence alignment of the region containing the K domain of OsMADS6 with those of OsMADS1, OsMADS5, OsMADS7, OsMADS8, OsMADS14, OsMADS15, OsMADS17, and OsMADS18. The region of OsMADS6 was divided into three regions: the KI region (amino acids 86–110), the KII region (amino acids 109–137), and the KIII region (amino acids 138–170). The entire K domain of OsMADS6 is underlined. The replaced amino acids are indicated below each Leu with arrows. The conserved hydrophobic residues, such as Leu, Ile, Val, and Met, are shaded. The numbers indicate the positions of mutagenized Leu residues and the first and last amino acids of the K region elucidated in this study.
