To review:
The outline of a research program for a crop species like wheat, rice or barley, that would utilize the genetics of flower development, to make a more productive variety.
Introduction:
The diploid barley (Hordeum vulgare L.,) and allohexaploid wheat (Triticum aestivum L.,) are the two important temperate cereal crop species. The early flowering is a vital feature that affects the grain yield and quality in both of these species. Direct identification of flowering genes and their molecular chracterization is a difficult task, as the genome size is large and complex. The use of bioinformatic approach for the prediction of flower related genes in barley and wheat compare to190 known Arabidopsis flowering genes may be helpful for the genetic information.

- The aim of a research project is to produce a hybrid plant having resistance to disease. The disease resistance trait is cytoplasmically encoded. The parent plants which are chosen for the development of the hybrid are sexually incompatible. Which tissue culture technique will be used to produce a hybrid using these sexually incompatible parents.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_forwardin flowering control of plant, describe a situation wherein there are mutations in at least one or all of the genes responsible for control of the floral development.arrow_forward
- You are a developmental geneticist and perform a mutagenesis screen in Arabidopsis looking for floral organ mutants. You identify a mutant phenotype that has the following organ arrangement, beginning in whorl 1: Sepal-Sepal-Carpel-Carpel Which class of floral identity genes has been mutated? A-B double mutant O A O SEPALLATA B сarrow_forwardPlant biologists are currently working to identify those Arabidopsis genes with unknown functions. If you were assigned to determine the function of a particular gene, how might you approach this task?arrow_forwardTrace the genetic steps in the development of a peanut plant that isresistant to insect larvae (table given). (Hint: You need to useAgrobacterium.)arrow_forward
- describe the information that is required in an application for the approval for the limited and controlled release of a papaya that was genetically modified to delay the process of fruit ripening.arrow_forward“To increase a specific attribute of a plant, somatic hybridisation is superior to genetic engineering and somatic variation.” Comment on this statement using the ideas of these approaches to plant improvement.arrow_forwardGenetic variation is indispensable for crop improvement. Discuss how heritable variation can be generated in crop plants?arrow_forward
- Explain how (a) the absence of class B gene expression produces the flower structures seen in class B mutants (see Figure 22.15c) and (b) the absence of class C gene expression produces the structures seen in class C mutants (see Figure 22.15d).arrow_forwardWhich of the following problems has/have been addressed through the development ofgenetically modified plants? 1. Vitamin deficiencies in children. 2. Susceptibility of crops to insect pests. 3 Accumulation of toxic ions in agricultural soils. 4. Both 1 and 2 are correct. 5. Women menstruation cycle.arrow_forwardPlants and animals usually battle each other; describe why and how this occurs. Once animal-pollinated flowers evolved, a new type of plant–animal interaction was possible; describe it. How is it possible for a mutation in aplant to be beneficial for both the plant and for an animal?arrow_forward
