Other claims from this paper (6)
- Observation On rice cv. IR24, disease index of the mutants ranged from 0.4 to 3.2 at 28 days after inoculation, significantly lower than that of the parent strain T7174R.
- Observation The chemical composition of EPS from the mutants was altered by the mutation.
- Observation None of the mutants with reduced EPS productivity completely lost virulence.
- Observation The mutants multiplied to almost the same level as T7174R in the area close to the inoculation point.
- Observation Distribution of the mutants tended to be restricted to the area around the inoculation point.
- Mechanism The authors suggest EPS productivity is not essential for multiplication of X. c. pv. oryzae in rice plants but is related to movement of bacteria in infected xylem vessels.
