Abstract(s)

SnRK1 (Snf1-related protein kinase 1) and TOR (target ofrapamycin) are evolutionarily conserved protein kinases thatlie at the heart of energy sensing, playing central andantagonistic roles in the regulation of metabolism and geneexpression. Increasing evidence links these metabolicregulators to numerous aspects of plant development, fromgermination to flowering and senescence. This prompts thehypothesis that SnRK1 and TOR modify developmentalprograms according to the metabolic status to adjust plantgrowth to a specific environment. The aim of this review is toprovide support to this hypothesis and to incentivize furtherstudies on this topic by summarizing the work that establishesa genetic connection between SnRK1–TOR and plantdevelopment.
