MCLV3p and [Ara3]CLV3p suppress marker genes in the SAM of clv3-2 mutant plants
(A-C) Seedlings (7 days) were treated with 100 nM CLV3 peptides for 6 h, and RNAs from the SAM tissues were analyzed by RT-qPCR. ACT2 (At3g18780) was used as an internal control to normalize the expression levels of WUS (At2g17950) (A), SOT17 (At1g18590) (B) and APK2 (At4g39940) (C). Error bars represent SEM (n = 10). ** indicates significant difference (one-way ANOVA test, p<0.001). n.s., not significant.
