Gall formation on certain angiosperms by Agrobacterium
Nodulation of Sesbania stems by nitrogen-fixing bacteria
Plant growth stimulation by phosphate– solubilising bacteria
Cyanobacterial symbiosis with some aquatic ferns

Hide Solution

Verified By Collegedunia

The Correct Option is A

Solution and Explanation

Plants and bacteria engage in various forms of interactions, and these interactions can have beneficial, harmful, or neutral effects on the plants involved. Additionally, the impact of a bacterium on a plant may change depending on the prevailing soil conditions. Among these interactions, the Agrobacterium crown gall phenomenon stands out as one of the most extensively researched and well-documented cases of bacterial-plant interactions. This bacterium possesses a sizable Ti plasmid, which serves as a natural genetic engineering tool in the field of plant genetic engineering.

Antimicrobials

Infections and diseases may be caused by different types of organisms like bacteria, fungi, and viruses, etc., in humans and animals. Antimicrobial agent is the drugs that are used to prevent the pathogenicity of microorganisms.

Examples: Antibiotics, antiseptics, and disinfectants.

It is used to prevent infections and diseases caused by pathogens. Different types of antimicrobial drugs are commonly available. These are as follows:

Antibacterial drug: is a drug that are used to inhibit the pathogenic activity of bacteria. Example: Zithromax.
Antifungal drug: A drug that is used to prevent the fungal activity in the host is called an antifungal drug. Example: Miconazole
Antiviral agent: A drug which is used to stop the pathogenic action of a virus is called as antiviral agents. Example: Tamiflu.
Antiparasitic drug: is a drug that are used to prevent the growth of pathogenic parasites. Example: Anthelmintics
