The plant pathogen Agrobacterium tumefaciens C58 can transfer a portion of its tumor-inducing (Ti) plasmid to plant hosts in response to the plant wound signals, including Acetosyringone. The portion transferred is aptly titled Transfer DNA (T-DNA) which encode genes involved in tumor production and biosynthesis of a unique bacterial food source called opines that provide an advantage to the inducing Agrobacterium. The Ti plasmid contains a number of genes, including the virulence region that enables T-DNA transfer. Epigenetics investigates how chemical modifications to DNA that don’t alter sequence are used to control gene expression (for example, genes involved in pathogen …
