Identification of a Pathogen-Induced Glycine max Transcription Factor GmWRKY1

다국어 초록 (Multilingual Abstract)

On screening pathogen-resistant soybean, we identified
a WRKY type transcription factor named a Glycine
max WRKY1 (GmWRKY1). Expression of GmWRKY1
gene was induced in the soybean sprout by Pseudomonas
infection. The GmWRKY1 was expressed in all of
the tissues with high levels in stems, leaves and
developing seeds. The protein GmWRKY1 contains
highly conserved two WRKY DNA-binding domains
having two C2-H2 zinc-finger motif (C-X4-5-C-X22-23-H-XH)
in its N-terminal and C-terminal amino acid
sequences. In electrophoresis mobility shift assay, the
GmWRKY1 protein bound specifically to W-box
elements in the promoters of defense related genes.
These results demonstrated that GmWRKY1 is one of
the soybean WRKY family genes and the plant-specific
transcription factors for defense processes.
