The AtVPS45-silenced plants secrete the VAC2 cargo. A, Plants from the F1 generation of crosses between a line homozygous for VAC2 (L1) and siVPS45-1a or siVPS45-10d display terminated flower and shoot meristems. B, Plants from the F2 generation of crosses between siVPS45-1a or siVPS45-10d and the L1 line. The plants shown were homozygous for VAC2 and either wild type (Wt) or AtVPS45 silenced (si1a and si10d). Arrows indicate flowers without carpels, and arrowheads indicate terminated shoot meristems.
