Legume nodulation and mycorrhizae formation; two extremes in host specificity meet.
Most higher plants have the ability to form arbuscular endomycorrhiza (AM); a symbiotic association of the plant root with fungi belonging to the order of Glomales. These fungi grow towards the inner cortical cells of the root where they differentiate into highly branched structures, the arbuscules (Figure 1). In AM symbiosis, the fungus also forms hyphae outside the plant and these provide a c...
متن کاملLegume nodulation
Are giant clams endangered? Giant clam species are extinct or in danger of extinction in many parts of their distributions, despite being listed in the IUCN Red List of Threatened Species and Appendix II of the Convention on International Trade in Endangered Species (CITES). The shells of the smaller species are often found in shell and tourist shops around the world. The large species have bee...
متن کاملR gene-controlled host specificity in the legume-rhizobia symbiosis.
Leguminous plants can enter into root nodule symbioses with nitrogen-fixing soil bacteria known as rhizobia. An intriguing but still poorly understood property of the symbiosis is its host specificity, which is controlled at multiple levels involving both rhizobial and host genes. It is widely believed that the host specificity is determined by specific recognition of bacterially derived Nod fa...
متن کاملRoles of Plant Hormones in Legume Nodulation
Legumes play a crucial role in agricultural and ecosystems based on their ability to convert atmospheric nitrogen gas into plant-available ammonium in symbiosis with soil bacteria commonly called ‘rhizobia’. This nitrogen-fixing ability makes legumes attractive as an agricultural, economical and environmentally friendly crop as their requirement for nitrogen fertilizer is reduced, leading to a ...
متن کاملMechanistic action of gibberellins in legume nodulation.
Legume plants are capable of entering into a symbiotic relationship with rhizobia bacteria. This results in the formation of novel organs on their roots, called nodules, in which the bacteria capture atmospheric nitrogen and provide it as ammonium to the host plant. Complex molecular and physiological changes are involved in the formation and establishment of such nodules. Several phytohormones...
