Validation of genes predominantly expressed in rice root hairs, using GUS reporter system. a to f, Expression patterns for reporter genes from promoter trap lines having T-DNA insertion within LOC_Os05g45900 (a and b), LOC_Os10g42750 (c and d), or LOC_Os12g02240 (e and f). g to l, GUS expression in root hairs from transgenic plants harboring LOC_Os02g42820 promoter::GUS construct (g and h), LOC_Os10g38340 promoter::GUS construct (i and j), or LOC_Os12g38010 promoter::GUS construct (k and l). Scale bar = 1 cm (a, c, e, g, i, and k) and 1 μm (b, d, f, h, j, and l)
