Project description:Rhizobium etli is a bacteria that fix nitrogen in symbiotic activity with Phaseolus vulgaris, the common bean plant. In order to accomplish this nitrogen reduction a especial environment is induced in nodules such that gene expression of bacteroid suffer a significant change with respect to its wild type life style. With the purpose to identify genetic alterations between these physiological states, replicates of microarray data were accomplished in similar conditions between bacteria cultivated in free-life (succinate-ammonia) and those carrying on nitrogen fixation inside nodule. Three independent biological materials with one dyeswap were performed.

Project description:Some intracellular bacteria are known to cause long-term infections for periods of time that last decades without compromising the viability of the host. Although of critical importance, the changes that intracellular bacteria suffer during this long process of residence in a host cell environment remain obscure. Here, we report an experimental approach to study the adaptations of intracellular mycobacteria forced by a long-term intracellular lifestyle. Long-term infection of host macrophages with mycobacteria was maintained for a period of years. Mycobacteria in the long-term infected macrophages underwent an adaptation process leading to impaired phenolic glycolipids (PGL) synthesis, preference for glucose as a carbon source and neutral lipids accumulation. These changes correlated with increased survival of mycobacteria in macrophages and mice during re-infection and specific expression of stress- and survival-related genes. Our findings identify bacterial traits implicated in the establishment of long-term cellular infections and represent a tool for understanding the physiological states of bacteria living in fluctuating intracellular environments.

Project description:Proteorhodopsin has been an ongoing hot topic for the past decade. However the complete physiological role of this extremely widely distributed protein remains mysterious. In this study we aim to give an insight to the physiology of a proteorhodopsin-containing sea ice bacteria – Psychroflexus torquis using gel-free label-free proteomic approach for the first time. We also addressed the life strategy that used by this organism to successfully inhabit extreme sea ice environment.
