Other claims from this paper (7)
- Association Strain R4 does not inhibit rice growth.
- Observation Strain R4 can enter rice roots and multiply in the intercellular spaces.
- Observation Rhizobium became intimately associated with rice seedling roots within 24-48 h.
- Observation Strain R4 caused structural changes resembling infection threads within rice root hairs.
- Observation Emerging lateral root sites provide a temporary entry point for rhizobia in rice, by root hair or crack entry.
- Observation All tested GFP-labelled Rhizobium strains infected root hairs near the base of growing lateral roots in rice.
- Mechanism Some rhizobial strains may infect rice root tissues via root hairs at emerging lateral roots and spread extensively through the rice root.
