Expression pattern of the PAR1 gene. A, Analysis of the expression of PAR1 in the roots, stems, rosette leaves, flowers, siliques, and seeds using qRT-PCR. The means of three replicates ± sd are shown. Similar results were obtained in three independent experiments. B to J, GUS expression in PAR1:GUS transgenic lines. GUS expression is shown in seedlings at the cotyledon stage (B) and eight-leaf stage (C), cauline leaf (D), inflorescence (E), flower (F), silique (G), immature seed (H), mature seed (I), and 2-d-old seedling (J).
