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 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 کاملAre Not Minimal under Certain Conditions
INFINITE LOCALLY FINITE GROUPS OF TYPE PSL(2, K) OR Sz(K) ARE NOT MINIMAL UNDER CERTAIN CONDITIONS JAVIER OTAL AND JUAN MANUEL PENA In classifying certain infinite groups under minimal conditions it is needed to find non-simplicity criteria for the groups under consideration . We obtain some of such criteria as a consequence of the main result of the paper and the classification of finite simpl...
