Implication

Experimental analysis demonstrates that suppressing SlMBP21 increases flower numbers and fruit yields in tomato plants, highlighting its role as a negative inflorescence regulator.

Key Points

Suppression of the sepallata gene SlMBP21 substantially increases tomato flower number and fruit yields, while noticeably enlarging sepals and inhibiting abscission zones.
Scanning electron microscopy and RNA sequencing reveal that silencing SlMBP21 represses sympodial inflorescence meristem maturation and alters hormone signaling pathways.
SlMBP21 interacts with key floral meristems regulators, including SlCMB1 and SFT, demonstrating that MADS-box transcription factors direct inflorescence architecture in crops.
