Large numbers of bacterial cells are not found in crown galls because?
Large numbers of bacterial cells are not found in crown galls because the bacteria responsible for gall formation (Agrobacterium tumefaciens) transfer only a small portion of their genetic material to the plant cell, triggering the formation of the gall. The bacteria do not actively multiply within the gall itself.
What are some examples of plant bacteria?
Some examples of plant bacteria include Rhizobium, which forms nodules on plant roots and fixes nitrogen for the plant, Agrobacterium, which can transfer genes into plants causing crown gall disease, and Pseudomonas syringae, which can cause diseases in a variety of plant species.
What is the functions of acetosyringone?
Acetosyringone is a plant phenolic compound that serves as a signaling molecule in the process of plant-microbe interactions. It is involved in the induction of the virulence genes in Agrobacterium tumefaciens, a bacterium that causes crown gall disease in plants. Acetosyringone helps to activate the transfer of DNA from the bacterium to the plant cells, leading to the formation of tumors.
What will happen to Agrobacterium when it losses it Ti plasmid?
Agrobacterium without the Ti plasmid will lose its ability to transfer genes into plant cells. It will not be able to cause crown gall disease in plants and will revert to its non-transforming state. This can affect its survival and competitiveness in the soil.
WHY Agrobacterium tumefaciens affect only dicots not monocots?
Agrobacterium tumefaciens can affect dicots because they have specific receptors on their cell surface that can recognize and bind to the bacterium. In monocots, these receptors are absent or different, making them less susceptible to infection by Agrobacterium. Additionally, the defense responses in monocots may hinder the establishment of the infection.

What is a gall and what causes it and is it healthy?
A gall is usually a growth on a plant that is caused by the secretions of an bacteria, larva, or other parasite and it harmless to the plant or tree, except for the disfigurement.

What is the common name for the disease cholelthiasis?
gall stones
What has the author CI Kado written?

How does typhoid result in cholecystitis?
This is a good question and need edit by expert. You have bacteremia in first week of typhoid. The bacteria probably settle there in gall bladder at that time. Cholecystitis is probably favoured by gall stones in the gall bladder.
What happen if a gallbladder stops working?
A person's gallbladder may stop working for a variety of reasons. Namely, it may be filled with stones or infected. If this is the case, the person will want to have their gallbladder removed so it does not cause them pain.
How do gallstones produce pale feces?
Gall stones prevent bile from moving out of the gall bladder into the small intestine, the absence of bile causes the pale faeces.
Why herbivores don't have gall bladder?
because they have bacteria in their digestive tract which secrete cellulase enzyme to digest cellulose... so they dont need gall bladder in their digestion...
What is causing lower right hand side abdomen pain and itching?
Lower right hand side abdomen pain and itching could be caused by several things. One item may be a problem with the gall bladder, such as gall stones or gall bladder disease.
Meaning of the idiom gall and wormwood?
something that causes you to have a bitter or highly unpleasant experience. Gall and wormwood are plants that were often referred to for their bitter taste in the Bible and Shakespeare. (The modern word gall now refers to bile, rather than a plant.)
