Hormone-centric multi-omics atlas of flower and early fruit development in tomato.

ABSTRACT: An unprecedented number of studies have explored hormone levels in plants; however, only a small fraction includes comprehensive metabolite analyses spanning multiple hormone classes. Here, we aim to establish a unique and detailed resource integrating the absolute concentrations of diverse hormone classes and their metabolites in tomato floral organs and early fruit tissues across developmental stages. We quantified 58 hormone metabolites from six chemical classes in whole flower buds, individual floral organs at five developmental stages, mature pollen, and early fruit tissues up to 15 days after anthesis. Hormone profiling was complemented by matched transcriptomic and shotgun proteomic analyses. This integrated dataset revealed distinct spatial and temporal hormone signatures, includin
