(ah) Five-day-old pTIR1:gTIR1-VENUS (ad) and pAFB2:gAFB2-VENUS (eh) seedlings were treated with dimethylsulphoxide (DMSO; a,c,e,g) or 10 μM GDA (G; b,d,f,h) for 24 h. The root tip (a,b,e,f) and root hair regions (c,d,g,h) of primary roots are shown. Arrows highlight lateral root primordia. (i) Relative levels of TIR1-VENUS and AFB2-VENUS transcripts (normalized to GAPC2 mRNA level) were determined by qRT–PCR after treating Col-0 seedlings with GDA for various times. Error bars are s.d., n=3. (j) Five-day-old pTIR1:gTIR1:VENUS seedlings were treated with DMSO, 100 μM bortezomib (bort) or both 100 μM bortezomib and 10 μM GDA (G) and remained at 22 °C or shifted to 29 °C for 5 h before imaging. Scale bar, 50 μm.
