Online ahead of print.ABSTRACTPlants cannot relocate themselves to avoid exposure to unfavorable temperature conditions and therefore rely on adaptive strategies that allow them to adjust their growth and development for survival. Shoot branching is a highly plastic trait regulated by several factors, including sugars, hormones, and light (Fichtner et al., 2021; Finlayson et al., 2010; Ongaro and Leyser, 2008). Although considerable progress has been made in understanding how these factors influence lateral bud outgrowth, much less is known about how warm temperatures affect this process. Likewise, the contribution of epigenetic modifications in regulating shoot branching remains poorly understood. Moreover, because most studies have focused on Arabidopsis thaliana, it is unclear whether these mechanisms are conserved in other species, including horticultural crop tomato (Solanum lycopersicum L.), where they may directly impact yield.PMID:41319001 | DOI:10.1016/j.molp.2025.11.010
