Effect of AtFBX92 down-regulation on rosette and leaf growth under standard conditions in vitro and cellular basis of the leaf size differences. (A) PRA of amiFBX92 and the WT over time from 5 until 21 DAS. Plants were grown in vitro on standard medium. Inset: PRA in log scale. Values represent the mean � SE (transgenic line= 22, nWT = 30). (B) Individual leaf size of 21-day-old WT and amiFBX92 plants grown in vitro. Values represent the mean � SE (n = 7). Significant differences (Student’s t-test): *P < 0.05; **P < 0.01 relative to the WT. (C) Representative pictures from the measurements shown in (B). (D) Average area, pavement cell number and pavement cell size of leaves 1 and 2 at 21 DAS of amiFBX92 plants relative to the WT. Values represent the mean � SE (n = 3).
