The organization of GFP-tagged cell components in untreated cells. The distribution of actin (A), microtubules (B), endoplasmic reticulum (ER) (C) and peroxisomes (D) in Arabidopsis thaliana expressing hTalin-GFP , TUA6-GFP , KKXX-GFP  and PTS-GFP , respectively. Images are maximum projections of z-series optical sections taken through the cortical cytoplasm underlying the outer wall of cotyledon epidermal cells before being touched with the microneedle. Bars = 10 μm.
