Also, how does Ri plasmid cause disease?

A soil bacterium Agrobacterium rhizogenes causes “hairy root” disease in some dicotyledonous plants. A bacterial Ri (root inducing) plasmid integrates its transfer-DNA (T-DNA) into the plant genome (DNA). As a result, rapidly growing and intensely branched (hairy) adventitious roots are developed.

Similarly, what is a helper plasmid? In the context of genetic transformation of plants, a helper plasmid is a plasmid present in Agrobacterium that provides functions required by the bacteria for transferring foreign DNA to a plant cell. They have been extremely important in plant genetic engineering.

People also ask, where is the Ti plasmid found?

The Ti plasmid is a member of a plasmid family found in Alphaproteobacteria.

What is hairy root disease?

Hairy root disease is characterized by an overabundant growth of adventitious roots at the site of infection (usually on the stems of plants near and immediately below the soil surface).
