ProteomicsAdaptation of Dinoroseobacter shibae to different kinds of oxidative stress
The Gram-negative photoheterotrophic bacterium Dinoroseobacter shibae is a member of the high abundant marine Roseobacter group. Living in the photic zone environment of marine ecosystems D. shibae is frequently exposed to oxygen. Oxic environments are hazardous and therefore effective defense mecha...

TranscriptomicsCPOP1 is the key heme synthesis enzyme required for nodule microenvironment control and successful symbiotic nitrogen fixation in Lotus japonicus
Heme is utilized as the cofactor of diverse proteins and plays critical roles in different redox reactions. The fixation active nodules of legumes are abundant with heme-containing leghemoglobin to buffer the oxygen concentration. Symbiotic rhizobia could also synthesize heme, and employ heme for ef...

TranscriptomicsA Ca2+/calmodulin-dependent protein kinase required for symbiotic nodule development: Gene identification by transcript-based cloning
Trancript Based Cloning (TBC) uses standard Gene Expression techniques to quickly isolate genes of interest and begin to determine their function. Using a particular mutant phenotype, identified during a programme of mutagenesis and screning, and a wild-type control we can quickly determine a list o...

TranscriptomicsGene expression data from phosphinothricin (PPT) treated Medicago truncatula root nodules
Nitrogen assimilation in plants is a tightly regulated process that integrates developmental and environmental signals. The legume-rhizobial symbiosis results in the formation of a specialized organ called root nodule, where the rhizobia fixes atmospheric nitrogen into ammonia. Ammonia is assimilate...
