abstract = {Low temperature is one of the most important environmental
factors that affect global survival of humans and animals
and equally importantly the distribution of plants and crop
productivity. Survival of metazoan cells under cold stress
requires regulation of the sensor‐kinase Target Of
Rapamycin (TOR). TOR controls growth of eukaryotic cells by
adjusting anabolic and catabolic metabolism. Previous
studies identified the Thyroid Adenoma Associated (THADA)
gene as the major effect locus by positive selection in the
evolution of modern human adapted to cold. Here we
investigate the role of THADA in TOR signaling and cold
acclimation of plants. We applied BLAST searches and
homology modeling to identify the AtTHADA (AT3G55160) in
Arabidopsis thaliana as the highly probable orthologue
protein. Reverse genetics approaches were combined with
immunological detection of TOR activity and metabolite
profiling to address the role of the TOR and THADA for
growth regulation and cold acclimation. Depletion of the
AtTHADA gene caused complete or partial loss of
full‐length mRNA, respectively, and significant
retardation of growth under non‐stressed conditions.
Furthermore, depletion of AtTHADA caused hypersensitivity
towards low‐temperatures. Atthada displayed a lowered
energy charge. This went along with decreased TOR activity,
which offers a molecular explanation for the slow growth
phenotype of Atthada. Finally, we used TOR RNAi lines to
identify the de‐regulation of TOR activity as one
determinant for sensitivity towards low‐temperatures.
Taken together our results provide evidence for a conserved
function of THADA in cold acclimation of eukaryotes and
suggest that cold acclimation in plants requires regulation
of TOR.},
