Regulatory-Associated Protein of TOR 1B (RAPTOR1B) regulates hormonal switches during seed germination in Arabidopsis thaliana.

ABSTRACT: Target of Rapamycin (TOR) regulates multiple growth- and metabolic-related processes in Arabidopsis thaliana as in all other eukaryotes. While several of these processes have been investigated in diverse Arabidopsis growth stages, little is known about hormonal and metabolic regulation of TOR during seed germination. This is mainly due to the fact that Arabidopsis knockout lines of TOR are embryo lethal. Here, we utilized the knockout lines of TOR-interacting protein, REGULATORY-ASSOCIATED PROTEIN OF TOR 1B (RAPTOR1B), to perform comprehensive hormone profiling during seed germination. We previously reported that RAPTOR1B positively regulates seed germination by maintaining the nutritional and hormonal balance. In the current analysis, dry and imbibed seeds as well as
