چکیده
Abstract The aim of this study was: (i) understand how upstream signaling modulated TOR-SnRK1 nexus; and (ii) establish an interplay between SnRK1-TOR nexus, sugar availability, sucrolytic enzyme activities, expression level key genes related to signalling metabolism, including trehalose, in vitro-grown ‘Myrobalan 29C’plum rootstock (Prunus cerasifera). Explants were cultivated Murashigue Skoog medium (MS) with trehalose (0; 1,0 10 mM). In 3 days, the antagonistic role PcSnRK1 PcTOR was confirmed plants treated 10mM possibly indicating that 29C’ not a stress condition. Furthermore, PcTREA up-regulation observed, which can lead glucose accumulation, turn is precursor sorbitol synthesis. Regarding growth parameters evaluated after 21 days vitro culture, uppermust number shoots explant length observed at trehalose. Such positive response may be due increase Glucose UDP-Glc content, direct products sucrose synthase (SuSy) enzyme. Consistent these results, highest availability molecules signal for TOR-activation. Interestingly, same condition, accumulation also have contributed ameliorate parameters.

متن کاملAtg9 antagonizes TOR signaling to regulate intestinal cell growth and epithelial homeostasis in Drosophila
Autophagy is essential for maintaining cellular homeostasis and survival under various stress conditions. Autophagy-related gene 9 (Atg9) encodes a multipass transmembrane protein thought to act as a membrane carrier for forming autophagosomes. However, the molecular regulation and physiological importance of Atg9 in animal development remain largely unclear. Here, we generated Atg9 null mutant...
متن کاملTOR Signaling in Growth and Metabolism
The target of rapamycin (TOR) is a conserved Ser/Thr kinase that regulates cell growth and metabolism in response to environmental cues. Here, highlighting contributions from studies in model organisms, we review mammalian TOR complexes and the signaling branches they mediate. TOR is part of two distinct multiprotein complexes, TOR complex 1 (TORC1), which is sensitive to rapamycin, and TORC2, ...

Minocycline is a broad spectrum, semi-synthetic tetracycline analog that is used to treat bacterial infection. Recently, this drug has been receiving increasing attention for its non-antibiotic properties, including anti-inflammatory, tumor suppressive, and neuroprotective effects. Drosophila is a useful model organism for studying human metabolism and disease. In this study, we investigated th...
متن کاملSnRK1 activates autophagy via the TOR signaling pathway in Arabidopsis thaliana
Autophagy is a degradation process in which cells break down and recycle their cytoplasmic contents when subjected to environmental stress or during cellular remodeling. The Arabidopsis thaliana SnRK1 complex is a protein kinase that senses changes in energy levels and triggers downstream responses to enable survival. Its mammalian ortholog, AMPK, and yeast ortholog, Snf-1, activate autophagy i...
