Gene Details:

• Gene ID: TraesCS2D01G502900
• Gene Symbol: TaSPL8
• Gene Name: SQUAMOSA PROMOTER BINDING-LIKE 8
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Wheat TaSPL8 Modulates Leaf Angle Through Auxin and Brassinosteroid Signaling.
• TaSPL8 knock-out mutants exhibit erect leaves due to loss of the lamina joint, compact architecture, and increased spike number especially in high planting density, suggesting similarity with its LIGULESS1 homologs in maize (Zea mays) and rice (Oryza sativa).
• Comparison of the transcriptome between the TaSPL8 mutant and the wild type revealed that TaSPL8 is involved in the activation of genes related to auxin and brassinosteroid pathways and cell elongation.
• TaSPL8 binds to the promoters of the AUXIN RESPONSE FACTOR gene and of the brassinosteroid biogenesis gene CYP90D2 and activates their expression.
• TaSPL8, the Homolog of LG1 in Maize and Rice, Affects Lamina Joint Development and Plant Architecture in Wheat,TaSPL8 might regulate lamina joint development through auxin signaling and the brassinosteroid biosynthesis pathway.
