N-fixing bacteria
What will be an ideal response?
are branching out like a tree
1. Flavonoids from plant bind Nod protein of Rhizobium, attracting bacteria to plant
2. Rhizobium cell binds to root hair
3. Root hair is induced to curl around Rhizobium
4. Plant cell envelope opens tube inward as infection thread
5. Rhizobium bacteria travel down infection thread, plant nucleus travels ahead
6. Rhizobium bacteria reach cortical cells
7. Bacteria enter cortical cells and differentiate to bacteroids
---N-fixing bacteria are integral to historical and modern agriculture
