Summary Introduction
To review:
The prevention of crown gall disease with the help of bacteria Agrobacterium radiobacter and the advantage of conjugation-deficient strain.
Introduction:
The crown gall disease is caused when bacteria causes infection in plants and due to those infections, lumpy swellings are observed, which are known as galls. The infection is caused on stems, roots, branches, and trunks. The crown gall disease is observed in the roots and stems of herbaceous and woody plants.

If heat inactivated the S strain dies and becomes nonlethal. Type R Streptococcus pneumoniae is a nonvirulent strain of bacteria. What would occur if one were to inject both the R strain and heat-killed S strains into a host organism such as the mouse? The R strain would be transformed into the virulent S strain and kill the host. Neither the S nor the R strain would change. The R strain would be transformed into the virulent S strain and not affect the host. The S strain would be transformed into the nonvirulent R strain and not affect the host The S strain would be transformed into the nonvirulent R strain and kill the host.arrow_forwardAn E. coli colony grew on minimal medium supplemented with arginine and leucine.
