Using yeast Main conclusion The 5 UTR of SBgLR enhances gene one-hybrid screening, we isolated a DNA-binding with one expression by regulating both its transcription and finger (Dof) protein gene (StDof23) and an AT-hook motif translation. nuclear-localized (AHL) protein gene (StAHL)frompotato pollen. Further investigation indicated that StDof23 inter- SBgLR (Solanum tuberosum genomic lysine rich) is a pol- acted with and positively regulated the ?31 to ?60 region; len-specific gene in Solanum tuberosum that encodes a moreover, StAHL interacted with and negatively regulated microtubule-associated protein.
