RMV1 is a PA transporter. (A) PA sensitivity of OX-C plants. Four-day-old plants were transferred to MS medium with the indicated concentration of PAs and grown for 6 d. (B) PA uptake of OX-C plants. Put, putrescine; Spm, spermine; Spd, spermidine. Error bars represent SD (n = 3). (C) Putrescine sensitivity of wild-type and rmv1 mutant plants. The wild type (Ler-1) and rmv1 mutant were germinated on MS medium containing the indicated concentrations of Put and grown for 9 d. The average frequencies of expanded green cotyledons are expressed as the average percentage and SD of plants grown on three plates containing 30 seeds each (*P < 0.01).
