Chapter 35, Problem 16TYK

The results from genetic studies of which of the following support the idea that plant form is not determined merely by the orientation of cell divisions?

  1. a. the gnom mutant of Arabidopsis, in which the first division of the zygote is symmetrical
  2. b. the tangled-1 mutant of maize, with its aberrant longitudinal division and normal leaves
  3. c. the KNOTTED-1 mutant in tomato plants, with its “super-compound” leaves
  4. d. the expression of the GLABRA-2 gene in root epidermal cells that do not develop root hairs

You 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 phenotype
You are a developmental geneticist studying flowering time variation in Arabidopsis. You perform a mutagenesis screen to identify mutants in the photoperiod pathway. Given what you know about photoperiodism in Arabidopsis, what phenotype are you looking for and under what photoperiodic conditions would you perform the experiment? delayed flowering in long days delayed flowering in short days same flowering in short days early flowering in short days same flowering in long days early flowering in long days
