Transcriptomic reprogramming and epigenetic regulation underlying pollination-dependent and auxin-induced fruit set in tomato.

ABSTRACT: The transition from flower to fruit, naturally triggered by flower pollination and known as fruit set, is instrumental for plant reproduction, seed formation, and crop yield. Notably, this developmental process can also proceed in the absence of flower fertilization, although it remains unclear whether pollination-dependent and pollination-independent fruit sets undergo similar transcriptomic reprogramming. Genome-wide transcriptomic profiling of the flower-to-fruit transition, either pollination-induced or triggered by auxin treatment, shows that both types of triggers modulate the expression of a common large set of genes primarily expressed in maternal tissues. These include genes related to auxin, gibberellin, brassinosteroid, and ethylene signaling. Furthermore, analysis of changes in
