Expression profiles of LjBGD2, LjBGD4, and LjBGD7 in 21-d-old L. japonicus seedlings. cDNA produced from mRNA isolated from different tissues was obtained from Forslund et al. (2004), and PCR was performed with specific primers amplifying LjBGD2, LjBGD4, LjBGD7, and ACTIN. LjBGD2 and LjBGD4 are detected in aerial tissues, while LjBGD7 is detected exclusively in roots.
