Activation of ADP-Glucose Pyrophosphorylase Gene Promoters by a WRKY Transcription Factor, AtWRKY20, in Arabidopsis thaliana L. and Sweet Potato (Ipomoea batatas Lam.)

Activation of ADP-Glucose Pyrophosphorylase Gene Promoters by a WRKY Transcription Factor, AtWRKY20, in Arabidopsis thaliana L. and Sweet Potato (Ipomoea batatas Lam.)

ADP–glucose pyrophosphorylase (AGPase) catalyzes the first limiting step in starch biosynthesis in plants. However, the direct transcriptional activator of the AGPase genes has not yet been determined. We have isolated a WRKY transcription factor cDNA, AtWRKY20, from Arabidopsis thaliana and purifie...
