Expression Patterns of SDT Determined by GUS Staining of SDT Promoter:GUS Lines and qRT-PCR Analyses and Changing Levels of Conjugated Spermidine in Arabidopsis Seedlings during Germination.
GUS staining of SDT promoter:GUS (A) and wild-type (B) Arabidopsis plants during germination. Days after germination are shown for each picture. Bars for 1 to 3 d and 4 to 5 d after germination are 0.2 and 1 mm, respectively.
(C) Levels of spermidine conjugates in wild-type Arabidopsis seedlings during germination. The data represent the mean value (±sd) of two independent biological replicates.
(D) Relative expression levels of SDT during germination determined by qRT-PCR. The data represent the mean value (±sd) of two independent biological replicates.
