One cluster termed “Thermoregulatory Clock Cluster” encompassed 46 differential expressed genes (DEGs) upregulated by SD but downregulated under LT condition. Functional analysis revealed enrichment in circadian clock and temperature responsiveness functions. In contrast, the “Growth Control Cluster” comprising 292 DEGs downregulated under SD but upregulated under LT, is enriched in functions associated with cell division and transcription regulation. This investigation underscores the pivotal roles of genes associated with circadian clock, temperature responsiveness, cell division and transcriptional regulation in orchestrating the entry and exit of grapevine buds from ED. Furthermore, we propose a mechanistic model wherein LT-induced repression of circadian clock genes provokes the upregulation of SD-suppressed genes that promote ED. Thus, the role of LT in releasing buds from ED can be understood at the molecular level.
