Gene Details:

• Gene ID: TRIUR3_00571
• Gene Symbol: TubZIP28
• Gene Name: Basic Leucine Zipper 28
• Genome:
• Species: Triticum urartu

Functional Descriptions:

• Here, a novel basic leucine zipper (bZIP) family transcription factor TubZIP28 was found to be preferentially expressed in the endosperm throughout grain-filling stages in Triticum urartu, the A genome donor of common wheat.
• When TubZIP28 was overexpressed in common wheat, the total starch content increased by c. 4%, which contributed to c. 5% increase in the thousand kernel weight.
• TubZIP28 is preferentially expressed in developing endosperms of T. urartu during grain-filling stages.
• Both in vitro and in vivo assays showed that TubZIP28 bound to the promoter of cytosolic AGPase and enhanced both the transcription and activity of the latter.
• TubZIP28 and TabZIP28 are transcriptional activators of starch synthesis first identified in wheat, and they could be superior targets to improve the starch content and yield potential of wheat.
