Gene Details:

• Gene ID: TraesCS4D02G109500.1
• Gene Symbol: TaASR1
• Gene Name: Abscisic stress-ripening protein 1
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• TaASR1, a transcription factor gene in wheat, confers drought stress tolerance in transgenic tobacco.
• Overexpression of TaASR1 in tobacco resulted in increased drought/osmotic tolerance, which was demonstrated that transgenic lines had lesser malondialdehyde (MDA), ion leakage (IL) and reactive oxygen species (ROS), but higher relative water content (RWC) and superoxide dismutase (SOD) and catalase (CAT) activities than wild type (WT) under drought stress.
• Overexpression of TaASR1 in tobacco also enhanced the expression of ROS-related and stress-responsive genes under osmotic stress.
• TaASR1 was localized in the cell nucleus and functioned as a transcriptional activator.
• Our results showed that TaASR1 functions as a positive factor under drought/osmotic stress, involved in the regulation of ROS homeostasis by activating antioxidant system and transcription of stress-associated genes.
