Proteomic Responses of <i>Roseobacter litoralis</i> OCh149 to Starvation and Light Regimen

Proteomic Responses of Roseobacter litoralis OCh149 to Starvation and Light Regimen

Roseobacter litoralis OCh149 is a type strain of aerobic anoxygenic phototrophic bacteria in marine Roseobacter clade. Its full genome has been sequenced; however, proteomic research, which will give deeper insights into the environmental stimuli on gene expression networks, has yet to be performed. In the present study, a proteomic approach was employed to analyze the status of R. litoralis OC...

Transcriptional and Proteomic Responses to Carbon Starvation in Paracoccidioides

BACKGROUND The genus Paracoccidioides comprises human thermal dimorphic fungi, which cause paracoccidioidomycosis (PCM), an important mycosis in Latin America. Adaptation to environmental conditions is key to fungal survival during human host infection. The adaptability of carbon metabolism is a vital fitness attribute during pathogenesis. METHODOLOGY/PRINCIPAL FINDINGS The fungal pathogen Pa...

Plant Responses to Sugar Starvation

Responses of soybean yield and yield components to light enrichment and planting density

Light intensity intercepted by the soybean canopy during the reproductive period is an important environmental factor determining soybean yield components and grain yield. A 2-year field experiment was conducted to investigate the effects of light enrichment and its interaction with planting density on yield formation of soybean cultivars. Light enrichment increased seed yield per plant and yie...

Proteomic adaptations to starvation prepare Escherichia coli for disinfection tolerance.

Despite the low nutrient level and constant presence of secondary disinfectants, bacterial re-growth still occurs in drinking water distribution systems. The molecular mechanisms that starved bacteria use to survive low-level chlorine-based disinfectants are not well understood. The objective of this study is to investigate these molecular mechanisms at the protein level that prepare starved ce...
