Integrated analysis of zone-specific protein and metabolite profiles within nitrogen-fixing Medicago truncatula-Sinorhizobium medicae nodules
Symbiotic nitrogen fixation (SNF) between rhizobia and legumes requires metabolic coordination within specialized root organs called nodules. Nodules formed in the symbiosis between S. medicae and barrel medic (M. truncatula) are indeterminate, cylindrical, and contain spatially distinct developmental zones. Bacteria in the infection zone II (ZII), interzone II-III (IZ), and nitrogen fixation z...
متن کاملNodule carbohydrate catabolism is enhanced in the Medicago truncatula A17-Sinorhizobium medicae WSM419 symbiosis
The symbiotic association between Medicago truncatula and Sinorhizobium meliloti is a well-established model system in the legume-Rhizobium community. Despite its wide use, the symbiotic efficiency of this model has been recently questioned and an alternative microsymbiont, S. medicae, has been proposed. However, little is known about the physiological mechanisms behind the higher symbiotic eff...
متن کاملThe intertwined metabolism of Medicago truncatula and its nitrogen fixing symbiont Sinorhizobium meliloti elucidated by genome-scale metabolic models
1 Genome-scale metabolic network models can be used for various analyses including the prediction of 2 metabolic responses to changes in the environment. Legumes are well known for their rhizobial symbiosis 3 that introduces nitrogen into the global nutrient cycle. Here, we describe a fully compartmentalised, mass 4 and charge-balanced, genome-scale model of the clover Medicago truncatula, whic...
متن کاملMtsym6, a gene conditioning Sinorhizobium strain-specific nitrogen fixation in Medicago truncatula.
The availability of a wide range of independent lines for the annual medic Medicago truncatula led us to search for natural variants in the symbiotic association with Sinorhizobium meliloti. Two homozygous lines, Jemalong 6 and DZA315.16, originating from an Australian cultivar and a natural Algerian population, respectively, were inoculated with two wild-type strains of S. meliloti, RCR2011 an...
متن کاملPartner choice in Medicago truncatula-Sinorhizobium symbiosis.
In nitrogen-fixing symbiosis, plant sanctions against ineffective bacteria have been demonstrated in previous studies performed on soybean and yellow bush lupin, both developing determinate nodules with Bradyrhizobium sp. strains. In this study, we focused on the widely studied symbiotic association Medicago truncatula-Sinorhizobium meliloti, which forms indeterminate nodules. Using two strains...
