Fig. 10From: Endoplasmic reticulum–localized UBC34 interaction with lignin repressors MYB221 and MYB156 regulates the transactivity of the transcription factors in Populus tomentosaModel of the roles of PtoUBC34 on the regulation of lignin biosynthesis. a. Schematic of cell with on-duty UBC34, and the gray part indicated PtoMYB221 absence in nucleus. b. Schematic of cell with off-duty UBC34, and the gray part indicated PtoMYB221 absence in ER compartmentsBack to article page
