Spatio-temporal expression of OsINV3 in the panicle using promoter::GUS lines. a-f GUS stained panicles at different progressing stages of panicle development until 1 DBH; a'-f' magnified images of the area marked in a-f. g-m Promoter::GUS expression in the developing endosperm at heading, 0 DAF, 2 DAF, 4 DAF, 6 DAF, 10 DAF and 15 DAF respectively. Vertical bars indicate 1 cm and horizontal bars indicate 1 mm. Arrows show the areas stained, isolating a vascular trace of OsINV3 expression in rachis branches (r), palea (p), lemma (l), nerves (n), anther (an), sterile lemmas (sl), rudimentary glume (rg), awn (a) and the dorsal end of the ovary (do)
