Graphical summary of the article. A, Previous work has shown that GL2 positively regulates trichome initiation. B, This study uses several lines with altered TCP4 expression. Lines where TCP4 function is lost are tcp2;4;10 and jaw-D. Lines where TCP4 is overexpressed are TCP4:VP16, pBLS::rTCP4:GFP, inducible mTCP4 jawD;GR, inducible mTCP4 Col-0;GR, and p35S::mTCP4:GR. The wild-type (WT) Columbia-0 (Col-0) is used as a control. C, Several techniques were used to study the indirect effect of TCP4 on GL2 and thus trichome number, including the use of existing databases, quantitative PCR (qPCR), and GUS expression in stably transformed lines. D, Several techniques were used to analyze TCP4 binding and activity, including genetic screens, binding motif prediction, electrophoretic mobility shift assay (EMSA), chromatin immunoprecipitation (ChIP), formaldehyde-assisted isolation of regulatory element (FAIRE), and transient luciferase assays. E, The authors propose that TCP4 affects trichome initiation through directly binding to the TCL1/2 promoter, which in turn inhibits GL2. Figure created with biorender.com.
