The spatiotemporal expression of OsWRKY67 in Nipponbare plants. a Relative expression levels of OsWRKY67 in different Nipponbare tissues. Young leaf, leaf at the three- to four-leaf stage; old leaf, leaf at the booting stage. The values are means ±SDs of three biological replicates. b-j GUS staining analysis of OsWRKY67 in different Nipponbare tissues. b leaf at the booting stage; c sprouting stage; d hull; e one-week old seedling; f root at the booting stage; g the second node at the booting stage; h the first node at the booting stage; i panicle at the booting stage; j panicle at the heading stage
