Identification of a mutant lacking pCASP2::GFP expression. (A and B) Stitched dissecting scope image of (A) wild-type plants expressing the pCASP2::GFP transcriptional reporter and (B) myb36-1 mutants that lack pCASP2::GFP expression. (C and D) Maximum-projection confocal images of (C) wild-type plants expressing the pCASP2::GFP transcriptional reporter and (D) myb36-1 mutants that lack pCASP2::GFP expression. (E) The mutation was mapped by sequencing to reveal a premature STOP (asterisk) at W58 in the coding region of MYB36, a putative transcription factor. (Scale bar, 50 μm.)
