A proposed model showing SlDELLA-SlPIF4-SLs/PTs signaling pathway regulates AMS and phosphate uptake in tomato. SlDELLA interacts with SlPIF4 to reduce SlPIF4 protein stability and its transcriptional activity toward downstream target genes, including SLs biosynthesis genes and AMS-specific phosphate transporter genes, thus promoting SLs accumulation, AMS development, and Pi uptake in tomato.
