Panicle growth and branching in RFL knockdown plants. (A) Mature deseeded wild-type and dsRNAiRFL panicles displayed for rachis length and branching. The primary branches (arrowheads), secondary branches (arrows), and spikelet pedicels (solid dots) are marked at representative positions. (B) Fold change in expression of branching regulators in dsRNAiRFL panicles compared with wild-type panicles determined by quantitative RT-PCR. (C) Schematic diagram of Ubi::RFL(AS) transgene. (D) Progressive reduction in the panicle branching and no secondary branches in these plants (line numbers at the bottom of each panicle). (E) Normalized fold change in the expression of branching regulators in RFL(AS) panicles. (Scale bars: 1.0 cm.)
