Jn. Mathis et al., GENETIC-VARIATION IN 2 CULTURES OF BRADYRHIZOBIUM-JAPONICUM-110 DIFFERING IN THEIR ABILITY TO IMPART DROUGHT TOLERANCE TO SOYBEAN, Current microbiology, 35(6), 1997, pp. 363-366
The polymerase chain reaction with arbitrary primers (RAPD) discrimina
ted between two separately maintained cultures of Bradyrhizobium japon
icum USDA 110 differing in symbiotic performance under drought conditi
ons. Since strain 110 is used in inoculum production, the use of RAPD
to monitor inoculum cultures could help to preserve their genetic comp
osition and prevent the loss of important symbiotic properties. The us
e of RAPD could also be extended to other B. japonicum strains current
ly used in inoculum production.
