Erratum to: Plant Growth Regul (2012) 68:111–127 DOI 10.1007/s10725-012-9704-4

Author would like to correct Fig. 2d which has little ‘apparent similarity’ with previously published figure. In this figure, the author has replaced this panel with representative image. The choice of appropriate panel was overseen earlier. This change does not impact the results reported in the paper. Author apologised for this unintentional error.
