Gene Details:

• Gene ID: TraesCS3B02G383000
• Gene Symbol: TaLAX1-3B
• Gene Name: TaLAX PANICLE1
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• The transcription factor TaLAX1 interacts with Q to antagonistically regulate grain threshability and spike morphogenesis in bread wheat.
• Our findings not only reveal the role of TaLAX1 in the regulation of wheat domestication traits, but also shed light on the regulatory mechanisms of the wheat domestication gene Q.
• Overexpression of TaLAX1 produces phenotypes, reminiscent of the q allele; loss-of-function TaLAX1 mutations confer compact spikes, largely similar to the Q-overexpression wheat lines.
• The two transcription factors TaLAX1 and Q disturb each others activity to antagonistically regulate the expression of the lignin biosynthesis-related gene TaKNAT7-4D.
• Overexpression of TaLAX1 homologs also significantly increases the regeneration efficiency of maize and soybean, suggesting that both monocot and dicot crops can benefit from this enhancement.
• This research explores overexpression of TaLAX PANICLE1 (TaLAX1), which markedly enhances regeneration efficiency, thereby boosting genetic transformation and genome editing in wheat.
