transfer of foreign DNA into crop plants ?
- ATrichoderma harzianum
- BMeloidogyne incognita
- CAgrobacterium tumefaciens
- DPenicillium expansum
View written solutionFree
Correct answer: C
Agrobacterium tumefaciens is the causal agent of crown gall disease (the formation of tumours) in over 140 species of dicot. This disease caused by a DNA plasmid (Ti plasmid) carried by bacterium and transferred to the plant cells.
