Disruption of the OsWRKY71 transcription factor gene results in early rice seed germination under normal and cold stress conditions.

ABSTRACT:

Background

Early seed germination in crops can confer a competitive advantage against weeds and reduce the time to maturation and harvest. WRKY transcription factors regulate many aspects of plant development including seed dormancy and germination. Both positive and negative regulators of seed germination have been reported in many plants such as rice and Arabidopsis. Using a transient expression system, we previously demonstrated that OsWRKY71 is a negative regulator of gibberellin (GA) signaling in aleurone cells and likely forms a "repressosome" complex with other transcriptional repressors. Hence, it has the potential to impact seed germination properties.

Results

In this study, we demonstrate that OsWRKY71, a Group IIa WRKY gene, appeared at the same time as seed-beari
