Optimization of Tomato Shoot Architecture by Combined Mutations in the Floral Activators FUL2/MBP20 and the Repressor SP

Shoot determinacy is a key trait affecting productivity in tomato, quantitatively governed by genes within the flowering pathway. Achieving an optimal balance of flowering signals is essential for shaping plant architecture and maximizing yield potential. However, the genetic resources and allelic d...
