Expression patterns of OsNAC103. A–M GUS staining of different tissues and organs in the transgenic plants with the fused construct of OsNAC103 promoter and GUS reporter. A Root. B Stem with tiller bud and intercalary meristem (indicated by arrowhead). C Leaf and leaf sheathe with paraphyll. D Root base with tiller bud and intercalary meristem (indicated by arrowhead). E Young leaf. F Mature leaf. G Senescent leaf. H Leaf sheath. I–K 5 cm, 15 cm and 20 cm young panicles, respectively. L Floral organ. M Seedling. N OsNAC103 expression levels in different tissues by qRT-PCR. SAM is shoot apical meristem. O OsNAC103 expression levels in leaves of different developmental stages in the field. P OsNAC103 expression levels in different leaf ages. a and b represent the second and fifth leaf of the rice plant from top down, respectively. Q OsNAC103 expression levels in truncated parts at the same leaf. a-d represent the four truncated parts of the fifth leaf, respectively. R GUS staining of seedlings at dark treatment
