Auxin regulates flower and fruit abscission,but how developmental signals mediate auxin transport in abscission remains ***,we reveal the role of the transcription factor BEL1-LIKE HOMEODOMAIN11(SlBEL11)in regulating auxin transport during abscission in tomato(Solanum lycopersicum).SlBEL11 is highly expressed in the fruit abscission zone,and its expression increases during fruit *** of SlBEL11 expression by RNA interference(RNAi)caused premature fruit drop at the breaker(Br)and 3d post-breaker(Br+3)stages of fruit *** and metabolome analysis of SlBEL11-RNAi lines revealed impaired flavonoid biosynthesis and decreased levels of most flavonoids,especially quercetin,which functions as an auxin transport *** suggested that SlBEL11 prevents premature fruit abscission by modulating auxin efflux from fruits,which is crucial for the formation of an auxin response ***,quercetin treatment suppressed premature fruit drop in SlBEL11-RNAi *** affinity purification sequencing(DAP-seq)analysis indicated that SlBEL11 induced expression of the transcription factor gene SlMYB111 by directly binding to its *** immunoprecipitation-quantitative polymerase chain reaction and electrophoretic mobility shift assay showed that *** MYELOBLASTOSIS VIRAL ONCOGENE HOMOLOG111(SlMYB111)induces the expression of the core flavonoid biosynthesis genes SlCHS1,SlCHI,SlF3H,and SlFLS by directly binding to their *** findings suggest that the SlBEL11-SlMYB111 module modulates flavonoid biosynthesis to fine-tune auxin efflux from fruits and thus maintain an auxin response gradient in the pedicel,thereby preventing premature fruit drop.
