Phylogenetic tree of Arabidopsis (At) and putative grapevine (Vv) predicted PIN proteins and time course of VvPINs expression in grapevine fruitlets. (a) Neighbor-joining tree based on full-length protein alignment. Bootstraps of 1000 iterations are given. Scale bar shows the number of amino acid substitutions per site. Clades containing VvPINs whose transcripts were detected in grapevine fruitlets are highlighted with bold branches. b Relative transcript abundance of VvPIN1, VvPIN1a, VvPIN1b and VvPIN4 was assessed in 7, 10, 14 and 17 DAF fruitlets. Transcript abundances are relative to the mean expression of the constitutive genes VvUBI1 and VvGPDH (see Methods section). Error bars represent SE of three replicates. Asterisk indicates that transcript abundance is significantly different from the corresponding value at 7 DAF (p < 0.05)
