Figure 5From: Interactions between ethylene and auxin are crucial to the control of grape (Vitis vinifera L.) berry ripeningChanges in transcript accumulation of selected auxin biosynthesis and GH3 genes in response to Ethrel in the 2012 trial. The expression of TAR1-TAR4, YUC1, GH3-1 and GH3-2 in pre-veraison Shiraz berries from the 2012 trial was analysed by qRT-PCR at the indicated time points after treatment with a Control or Ethrel solution (see Figure 1). Control, dark grey bars; Ethrel, light grey bars. CV, veraison of Control fruit; EV, veraison of Ethrel-treated fruit. All data represent means ± SE (n = 3). Asterisks indicate significant differences of the mean values of Ethrel-treated samples from the mean values of Control samples as determined with Student’s t-test (*p < 0.05, **p < 0.01).Back to article page
