nodule formation in legumes
|
1.plants release flavenoids to attract rhizobium (causes root hairs to curl and trap bacteria)
2. In response, rhizobium produces Nod factor. 3. triggers cell proliferation in the root 4.bacteroids in the membrane vesicles 5.plant produces leghemoglobin which transports O2 to the rhizobium |
|
|
symbiotic relationship between plants nad bacteria
|
nodule bacteria gets carbs and leghemoglobin while plants get nitrogen from the bacteria
