Metal concentration of seeds of grafted plants. Metal content of the seeds produced by ungrafted wild-type plants (WT), by wild-type self-grafted plants (WT+WT), by ysl1ysl3 inflorescences grafted to wild-type rosettes (ysl1ysl3+WT), and by ysl1ysl3 ungrafted plants was determined using ICP-MS. As a control for the effect of inflorescence grafting on seed metal concentration, seeds from ungrafted wild-type plants were also measured. WT+WT and ysl1ysl3 samples contain four replicates, ysl1ysl3+WT sample contains six replicates, and ungrafted wild-type sample contains 10 replicates. Asterisks indicate P < 0.05 by t test.
