Complex I and its involvement in redox homeostasis and carbon and nitrogen metabolism in Rhodobacter capsulatus.
A transposon mutant of Rhodobacter capsulatus, strain Mal7, that was incapable of photoautotrophic and chemoautotrophic growth and could not grow photoheterotrophically in the absence of an exogenous electron acceptor was isolated. The phenotype of strain Mal7 suggested that the mutation was in some gene(s) not previously shown to be involved in CO(2) fixation control. The site of transposition...
متن کاملNitrogen and carbon storage in alpine plants.
Alpine plants offer unique opportunities to study the processes and economics of nutrient storage. The short alpine growing season forces rapid completion of plant growth cycles, which in turn causes competition between vegetative and reproductive growth sinks during the early part of the growing season. Mobilization of stored nitrogen and carbon reserves facilitates competing sinks and permits...

متن کاملKeap1 degradation by autophagy for the maintenance of redox homeostasis.
The Kelch-like ECH-associated protein 1 (Keap1)-NF-E2-related factor 2 (Nrf2) system is essential for cytoprotection against oxidative and electrophilic insults. Under unstressed conditions, Keap1 serves as an adaptor for ubiquitin E3 ligase and promotes proteasomal degradation of Nrf2, but Nrf2 is stabilized when Keap1 is inactivated under oxidative/electrophilic stress conditions. Autophagy-d...
متن کاملPolyamines as redox homeostasis regulators during salt stress in plants
The balance between accumulation of stress-induced polyamines and reactive oxygen species (ROS) is arguably a critical factor in plant tolerance to salt stress. Polyamines are compounds, which accumulate in plants under salt stress and help maintain cellular ROS homeostasis. In this review we first outline the role of polyamines in mediating salt stress responses through their modulation of red...
