Plant flotillins are required for infection by nitrogen-fixing bacteria.
To establish compatible rhizobial-legume symbioses, plant roots support bacterial infection via host-derived infection threads (ITs). Here, we report the requirement of plant flotillin-like genes (FLOTs) in Sinorhizobium meliloti infection of its host legume Medicago truncatula. Flotillins in other organisms have roles in viral pathogenesis, endocytosis, and membrane shaping. We identified seve...
متن کاملFerredoxins from Nitrogen-Fixing Bacteria
Two ferredoxins have been purified from N2-fixing Mycobacterium flavum. Ferredoxin I had a minimum molecular weight (by amino acid analysis) of 11 230 and contained 7.4 mol Fe and 7.0 mol S2per mol. The ratio of the absorbance at 400 nm to that at 275 nm was 0.7. Ferredoxin I1 had a minimum molecular weight of 13478 and contained 3.4 mol Fe and 3.2 mol S2per mol. The ratio of the absorbance at ...
متن کاملAmmonia Accumulation of Novel Nitrogen-Fixing Bacteria
Nitrogen is an essential element for many biological processes, including those occurring in plants (Ogura et al., 2006). Despite the abundance of atmospheric nitrogen, production of nitrogen fertilisers by the Harber–Bosch process is increasing annually due to the deficiency of ammonia produced by biological nitrogen fixation—the enzyme-catalyzed reduction of nitrogen gas (N2). Concern over ‘g...
متن کاملNitrogen-Fixing Bacteria in Eucalyptus globulus Plantations
Eucalypt cultivation is an important economic activity worldwide. In Portugal, Eucalyptus globulus plantations account for one-third of the total forested area. The nutritional requirements of this crop have been well studied, and nitrogen (N) is one of the most important elements required for vegetal growth. N dynamics in soils are influenced by microorganisms, such as diazotrophic bacteria (D...
متن کاملRegulation of Differentiation of Nitrogen-Fixing Bacteria by Microsymbiont Targeting of Plant Thioredoxin s1
Legumes associate with rhizobia to form nitrogen (N2)-fixing nodules, which is important for plant fitness [1, 2]. Medicago truncatula controls the terminal differentiation of Sinorhizobium meliloti into N2-fixing bacteroids by producing defensin-like nodule-specific cysteine-rich peptides (NCRs) [3, 4]. The redox state of NCRs influences some biological activities in free-living bacteria, but ...
