Bacteria adapt to shifts from rapid to slow growth, and have developed strategies for long-term survival during prolonged starvation and stress conditions. We report the regulatory response of C. crescentus to carbon starvation, based on combined high-throughput proteome and transcriptome analyses. Our results identify cell cycle changes in gene expression in response to carbon starvation that ...

Phosphorus (P) deficiency is a major threat to the crop production, and for understanding response mechanism of plant roots, P stress may facilitate development crops with increased tolerance. Phosphorylation plays critical role in regulation proteins responses biotic abiotic stress; however, its functions starvation/resupply are largely unknown barley ( Hordeum vulgare ) growth. Here, we perfo...

The broad host-range pathogen Serratia marcescens survives in diverse host and non-host environments, often enduring conditions in which the concentration of essential nutrients is growth-limiting. In such environments, carbon and energy source starvation (carbon-starvation) is one of the most common forms of stress encountered by S. marcescens. Related members of the family Enterobacteriaceae ...

The responses of Pseudomonas putida KT2442 to various forms of nutrient starvation and stress conditions were examined by two-dimensional polyacrylamide electrophoresis. Carbon deprivation resulted in a temporal expression of two classes of starvation-induced proteins: one class was transiently expressed during the initial phase of starvation, and the second class was expressed throughout the e...

Intestinal epithelial cells are tightly bound by tight junction proteins (TJP) which dynamic and sensitive to environmental stress. However, the role of endocytic pathway in regulation TJP abundance integrity during nutrient stress is poorly understood. Therefore, this study was conducted investigate starvation mechanism process. IPEC-J2 were subjected Krebs-Ringer bicarbonate buffer (KRB) TJP,...

Environmental stress affects basic organismal functioning and can cause physiological, developmental, and reproductive impairment. However, in many nonmodel organisms, the core molecular stress response remains poorly characterized and the extent to which stress-induced transcriptional changes differ across qualitatively different stress types is largely unexplored. The current study examines t...

In fission yeast, Sty1 and Gcn2 are important protein kinases that regulate gene expression in response to amino acid starvation. The translation factor subunit Int6/eIF3e promotes Sty1-dependent response by increasing the abundance of Atf1, a transcription factor targeted by Sty1. While Gcn2 promotes expression of amino acid biosynthesis enzymes, the mechanism and function of Sty1 activation a...

BACKGROUND Analysis of many proteins produced during the transition into the stationary phase and under stress conditions (including starvation stress) demonstrated that a number of novel proteins were induced in common to each stress and could be the reason for cross-protection in bacterial cells. It is necessary to investigate the synthesis of these proteins during different stress conditions...

Most animals face periods of food shortage and are thus expected to evolve adaptations enhancing starvation resistance. Most of our knowledge of the genetic and physiological bases of those adaptations, their evolutionary correlates and trade-offs, and patterns of withinand among-population variation, comes from studies on Drosophila. In this review we attempt to synthesize the various facets o...
