ABSTRACT

The Target Of Rapamycin (TOR) pathway is essential for the integration of environmental signals, nutrients and energy availability with growth factors control on development and differentiation in eukaryotic organisms. Discovery and characterization of the pathway in plants is more recent and has been poorly studied in crops. Specifically, a pathway similar to that corresponding to the mammalian TORC1 complex was described, but with peculiarities of the plant lineage involving responses to phytohormones and light, stress adaptation and plant life span control. TOR has important impacts on the metabolic profile, cell proliferation/differentiation balance and coordination of gene expression in response to glucose, auxins and stress. Here we describe the main components of the TOR pathway discovered in the model plant Arabidopsis, upstream of TOR signaling, downstream processes regulation, and present some of the findings as an attractive target for crop improvement.
