miR156a‐targeted SBP‐Box transcription factor SlSPL13 regulates inflorescence morphogenesis by directly activating SFT in tomato
2020
Overview
The inflorescences and lateral branches of higher plants are generated by lateral meristems. The structure of the inflorescence has a direct effect on fruit yield in tomato (Solanum lycopersicum). We previously demonstrated that miR156a plays important roles in determining the structures of the inflorescences and lateral branches in tomato by suppressing the expression of the SQUAMOSA PROMOTER BINDING PROTEIN LIKE (SPL) transcription factor gene family. However, information on regulatory pathways associated with inflorescence morphogenesis is still lacking. In this study, we demonstrate that SPL13 is the major SPL involved in miR156a‐regulated tomato inflorescence structure determination and lateral branch production. Suppressing the expression of SPL13 in tomato increases the number of inflorescences on vegetative branches and lateral branches, decreases the number of flowers and fruit, and reduces fruit size and yield. Genetic and biochemical evidence indicate that SPL13 controls inflorescence development by positively regulating the expression of the tomato inflorescence‐associated gene SINGLE FLOWER TRUSS (SFT) by directly binding to its promoter region. Thus, our findings provide a major advance to our understanding of the miR156a‐SlSPL‐based mechanism that regulates plant architecture and yield in tomato.
