The Oryza sativa short postembryonic roots 1 (OsSPR1) expression pattern revealed by GUS staining and RT-PCR. The images show the GUS staining pattern obtained in OsSPR1 promoter:GUS transgenic plants in (a) a primary root; (b) a primary root elongation zone; (c) a primary root tip; (d) a mature lateral root; (e) the base of a mature lateral root; (f) a mature lateral root tip; (g) an elongating lateral root; (h) an elongating lateral root tip; (i) the node region of a young uppermost internode; (j) an auricle; (k) a cross-section of an uppermost node; (l) a cross-section of a stem; (m) young spikelets; (n) flowering spikelets; (o) the pedicel of a young panicle; (p) pistils; (q) a stem; (r) a leaf. Bars: (a, d, g, k–p) 100 lm; (i, j, q, r) 200 lm; (b, c, e, f, h) 50 lm. (s) Expression pattern of OsSPR1 obtained using RT-PCR. cDNA was amplified from the root (R), stem base (SB), stem (S), leaf (L), and panicles (P) for the wild type (WT) and spr1 mutant (mutant), respectively.
