Chapter 38, Problem 17TYK
Which of the following techniques is being developed to reduce the likelihood that introduced genes for herbicide or insect resistance will escape to closely related weed species?
- a. engineering flowers to self-fertilize and remain closed so that pollen is not released
- b. breeding male sterility into transgenic plants so that they have no pollen to be transferred to nearby weeds
- c. engineering the gene of interest into chloroplast DNA, which is inherited from the maternal plant and is not transferred by pollen
- d. All of the above would reduce the risk of crop-to-weed transgene escape.

Explain the significance of mutation in plant breeding. Give an example of a disease resistant variety of cultivated plant induced by mutation.arrow_forwardYou are a developmental geneticist studying flowering time variation in Arabidopsis. You perform a mutagenesis screen to identify mutants in the photoperiod pathway. You conduct the screen and find two different plants that show the same mutant phenotype. You then use a complementation test. What is the predicted outcome of this test if both phenotypes are caused by mutations in separate genes? recover the wild type phenotype overexpress the gene O recover the mutant phenotypearrow_forward
- Trace the genetic steps in the development of a peanut plant that isresistant to insect larvae (table given). (Hint: You need to useAgrobacterium.)arrow_forwardConsider the following hypothetical gene a plant g&T produces a protein that impacts the stem length. There are two alleles for GT which produces long stem and tea little tea which results in short stint. Which of the following genome types above would have a different pheno type? And what would the phenotype be for the genotype?arrow_forwardYou are studying a plant with tissue comprising both green and white sectors. You wish to decide whether this phenomenon is due (1) to a chloroplast mutation of the type considered in this chapter or (2) to a dominant nuclear mutation that inhibits chlorophyll production and is present only in certain tissue layers of the plant as a mosaic. Outline the experimental approach that you would use to resolve this problem.arrow_forward
- Please elaborate the phenomenon of cytoplasmic male sterility in plants. Also discusses its utility in plant breeding.arrow_forwardGenetic engineering of plants provides an opportunity to alter their properties or performance in order to improve upon their utility. Such technology may be used to modify the expression of genes already present in the plants, or to introduce new genes of other species with which the plant cannot be bred conventionally. In fact, humans have engaged in genetic manipulation for millennia, producing plant and animal varieties through selective breeding and hybridization that significantly modify genomes of organisms. How has this technology created novel genetic information by specific alteration of cloned genes? (provide an example). Why do you think modern genetic engineering, has met with so much opposition? Should some forms of genetic engineering be of greater concern than others? Explain. In your response provide a specific example from literature to describe the implications of this technology (good or bad).arrow_forward3a)“Somatic hybridisation is preferable to genetic engineering and somaticvariation to improve a specific trait of a plant.” Comment this statement based on the principles of these approaches in improving the plants.arrow_forward
