Expression pattern of the 5' regulatory regions of the TRY promoter as revealed by GUS reporter gene expression. The GUS expression pattern driven by different promoter fragments was monitored on young leaves at stages where new trichomes were still initiated (A, C, E, G and I) and for slightly older leaves in which trichome initiation had already stopped (B, D, F, H and J). Pictures were taken in each case from one of the strongest T2 lines carrying the respective TRY promoter GUS fusion construct: pTRY-A, B:GUS (A, B), pTRY-A:GUS (C, D), pTRY-A3, B:GUS (E, F), pTRY-A4, B:GUS (G, H) and pTRY-A5, B:GUS (I, J). Bars indicate the magnification of the images.
