Fig 8. OBP4 regulates plant root system architecture.

Fig 8

(A) Phenotypic observation and (B) analysis of the root system in constitutive overexpression and knockdown OBP4 transgenic plants. The white bar indicates 1.2 cm in length. (C) Phenotypic analysis of lateral root emergence (LRE) was performed by synchronizing lateral root (LR) formation with a gravity stimulus for 22 and 38 hours. Compared with that in the control plants, the LRE in the OBP4 overexpression plants and OBP4 knockdown plants was delayed and promoted, respectively. The data are shown as percentages and the error bars represent SDs (n = 8–12). Approximately 24–36 lateral root primordia (LRP) were observed in 35S::OBP4 plants. Approximately 100 LRP were observed in OBP4 knockdown transgenic plant. *indicates significant differences (p<0.05).
