The POTH15 promoter expression. The prom POTH15::GUS construct (A). Promoter activity of POTH15 in the shoot apex (B), nodes (C), at lateral root initiation (H, arrows), stolon tip (I), stolon meristem (J), root–stolon junction (K, arrows), mini-tuber (K, arrow), tuber eyes (L, arrows), tuber pith (M), meristems of 2-week-old (N) and 4-week-old excised tuber sprouts of S. tuberosum cv. Désirée (O, P; where P is a magnified image of O, highlighted region). L.S. of nodal and internodal region showing POTH15 promoter activity in axillary meristem (D, E; where E is a magnified image of D, highlighted region). T.S. of nodal region (F) and internodal region showing POTH15 promoter activity in vascular tissues (G). Scale bars: (C, H) 50mm; (F, G, M, P) 100mm; (B, D, E, I–L, N, O) 200mm. Arrows indicate the regions of POTH15 promoter activity.
