Legume 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 کاملSwitch from intracellular to intercellular invasion during water stress-tolerant legume nodulation.
Rhizobia colonize their legume hosts by different modes of entry while initiating symbiotic nitrogen fixation. Most legumes are invaded via growing root hairs by the root hair-curl mechanism, which involves epidermal cell responses. However, invasion of a number of tropical legumes happens through fissures at lateral root bases by cortical, intercellular crack entry. In the semiaquatic Sesbania...
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...
متن کاملRhizobium -Legume Nodulation: Life Together in the Underground Review
How good and how pleasant it is for organisms to dwell together in unity! And, probably, how common it is in the biological world. This review concerns a dramatic association, one of the few that has been studied in detail: the nitrogen fixing symbiosis between certain plants and microbes Rhizobium bacteria stimulate leguminous plants to develop root nodules, which the bacteria infect and inhab...
