Host-secreted antimicrobial peptide enforces symbiotic selectivity in Medicago truncatula.
Legumes engage in root nodule symbioses with nitrogen-fixing soil bacteria known as rhizobia. In nodule cells, bacteria are enclosed in membrane-bound vesicles called symbiosomes and differentiate into bacteroids that are capable of converting atmospheric nitrogen into ammonia. Bacteroid differentiation and prolonged intracellular survival are essential for development of functional nodules. Ho...
متن کاملMedicago truncatula symbiotic peptide NCR247 contributes to bacteroid differentiation through multiple mechanisms.
Symbiosis between rhizobia soil bacteria and legume plants results in the formation of root nodules where plant cells are fully packed with nitrogen fixing bacteria. In the host cells, the bacteria adapt to the intracellular environment and gain the ability for nitrogen fixation. Depending on the host plants, the symbiotic fate of bacteria can be either reversible or irreversible. In Medicago a...
متن کاملDisulfide cross-linking influences symbiotic activities of nodule peptide NCR247.
Interactions of rhizobia with legumes establish the chronic intracellular infection that underlies symbiosis. Within nodules of inverted repeat-lacking clade (IRLC) legumes, rhizobia differentiate into nitrogen-fixing bacteroids. This terminal differentiation is driven by host nodule-specific cysteine-rich (NCR) peptides that orchestrate the adaptation of free-living bacteria into intracellular...
متن کاملComparative Analysis of the Symbiotic Efficiency of Medicago truncatula and Medicago sativa under Phosphorus Deficiency
Phosphorus (P)-deficiency is a major abiotic stress that limits legume growth in many types of soils. The relationship between Medicago and Sinorhizobium, is known to be affected by different environmental conditions. Recent reports have shown that, in combination with S. meliloti 2011, Medicago truncatula had a lower symbiotic efficiency than Medicago sativa. However, little is known about how...
متن کاملInsights into symbiotic nitrogen fixation in Medicago truncatula.
In silico analysis of the Medicago truncatula gene index release 8.0 at The Institute for Genomic Research identified approximately 530 tentative consensus sequences (TC) clustered from 2,700 expressed sequence tags (EST) derived solely from Sinorhizobium meliloti-inoculated root and nodule tissues. A great majority (76%) of these TC were derived exclusively from nitrogen-fixing and senescent n...
