Gene expression, enzyme assay, and polyamine contents in wild type Arabidopsis thaliana. a relative expression of the five AtSAMDC genes (white bars = 2-day and gray bars = 10-day old seedlings; b AtSAMDC gene expressions in 5-week old mature plant parts; c SAMDC enzyme activity in 5-week old mature plant parts; and (d) polyamine contents in seedlings and mature plant parts (abbreviations used: RL = rosette leaf, CL = cauline leaf, 2 d = 2 day whole seedlings, 10 d = 10 day whole seedlings, wk. = week, RT = root, F = flower, B = bud, LS = lower stem, US = upper stem, GSi = green silique, MSi = mature silique). Data are mean ± SE of 3–4 biological replicates
