Expression analysis of PgABC candidate genes under MeJA treatment in ginseng adventitious roots by qRT-PCR. Nine PgABC gene expressions were analyzed at different MeJA treatment times (0, 6, 12, 24, 48, 72, and 96 h), significant differences relative to the control group (0 h) are indicated as follows: “*” p ≤ 0.05, “**” p ≤ 0.01, and “***” p ≤ 0.001
