Summary Introduction
To review:
The relationship between microbial gene exchange and crown gall disease in plants.
Introduction:
Crown gall is a common disease in plant, caused by a soil bacterium Agrobacterium tumefaciens. It usually infects herbaceous plants and woody shrubs including berries, roses, and grapes. The bacteria enter the plant through roots and stems. The symptoms of this disease include round growths that can be seen just above the soil line.

- Agrobacterium tumefaciens is a bacterium that infects a wide range of broad-leaved plants. During infection, a plasmid called Ti is transferred into the plant cells, where that plasmid DNA is integrated into the plant’s genome. Some of the genes encoded by this plasmid are expressed by host cell machinery in the plant cell. These gene products produce plant hormones which stimulate cell division in the infected cells, causing the development of a plant tumor which provides an environment for that bacterium to grow. You are studying a novel isolate of A. tumefaciens and want to determine which of the genes on the Ti plasmid are expressed in the bacterium, and which are expressed in the plant. You start by sequencing the Ti plasmid. a) Considering the DNA sequence of Ti, describe two specific genetic features that would help you to differentiate whether a given gene is likely expressed in the plant or bacterium. b) You collect plant tumor tissue, containing both bacterial and plant…arrow_forwardThe figure below shows the life cycle of the fungus Neurospora. The adult stage of the Neurospora is a multicellular haploid. b) Neurospora has an arginine amino acid synthesis pathway shown below. Suppose I take the strain above that only grows with arginine supplements and cross it to a different mutant Neurospora strain that grows with arginine and citrulline supplements but not with ornithine supplements. Assuming gens A, B, and C are unlinked and there is only one mutation per stain: What percentage of the progeny will grow on ornithine? What percentage on citrulline? What percentage on arginine?arrow_forwardName the bacterium which is used to produce insect-resistant plants by genetic engineering.arrow_forward
- A group of genetics students mix two auxotrophic strains of bacteria: one is leu+ trp+ his− met− and the other is leu− trp− his+ met+. After mixing the two strains, they plate the bacteria on minimal medium and observe a few prototrophic colonies (leu+ trp+ his+ met+). They assume that some gene transfer has taken place between the two strains. How can they determine whether the transfer of genes is due to conjugation, transduction, or transformation?arrow_forwardIf a scientist wanted to introduce a transgene into a plant, which of these techniques would they be likely to use? A.) Inject a P element vector into a pollen grain. B.) Inject a genetically modified nucleus into an enucleated plant cell. C.) Inject a transgene into a seed. D.) Infect plant cells with bacteria containing T-DNA.arrow_forwardWhat is horizontal gene transfer?arrow_forward
