- The ABCDE Model of flower development dictates the combination of transcription factors require to initiate each whorl of a flower. Based on the diagram below, what would happen if: Carpels and ovules Sepal Petal Stamen 2 4 Whorl A Genes E 25-40 The ABCDE model of floral organ determination in Arabidopsis In addition to the A-, B-, and C-function genes of the ABC model, this model includes two additional gene classes, D and E. In the ABCDE model, class A + E genes specify sepals; class A + B + E, petals; class B +C +E, stamens; class C + E, carpels; and class C+ D + E, ovules. 1. Gene D was non-functional: 2. Gene E was non-functional: 3. Only Gene A was functional: 4. Gene B and E were non-functional: 5. Only Gene A and Gene E were functional: Hint: If Gene A was non-functional the flower would have no sepals or petals, it would be composed of only stamens and carpels.Excluding leaf senescence, describe three instances of programmed cell death as a part of normal plant development.One example of innovation from an unexpected source came from the study of tumor-like plant growths caused by Agrobacterium tumefaciens. What information did the study of the plant tumors provide that was critical for plant genetic engineering? O learning that metastasis is critical for tumor progression Olearning how A. tumefaciens uses plant pathways to synthesize beta carotene Oknowledge of plant tumor suppressor genes and their role in tumor development Othe ability of A. tumefaciens to integrate its genes into the plant genome
- Can you solve all the parts to this question please a) What is the role of the LEAFY gene in floral development? (b) What is the phenotype of the leafy mutant? (c) Most of the ABC program genes are directly regulated by the transcription factor LEAFY (LFY). Still, LFY is expressed broadly throughout the floral meristem when the discrete A, B, and C domains are established. Discuss how this single broadly expressed transcription factor can generate distinct domains of ABC gene expression. Feel free to use diagrams.Can you clearly type the answers to the all the parts to this question please a) What is the role of the LEAFY gene in floral development?

- In Arabidopsis, it is well-known that a pulse of full-spectrum light during the night (in an otherwise long night) will induce flowering. This suggests that plants measure the length of night, and not the length of day. If the pulse of light during the night was blue light instead of full spectrum light, what would be the flowering time response of a plant with a knockout in cry2 (relative to wild type in the same conditions)? Explain.E2F is a transcriptiion factor that activates genes for DNA rep- proteins. In addition with RBR, E2F is one of the controls for G1 to S transition. Why would E2F have a role in totipotyency of plant cells?In roses, the synthesis of red pigment is by two steps ina pathway, as follows:colorless intermediate gene Pmagenta intermediate red pigment gene Qa. What would the phenotype be of a plant homozygousfor a null mutation of gene P?b. What would the phenotype be of a plant homozygousfor a null mutation of gene Q?c. What would the phenotype be of a plant homozygousfor null mutations of genes P and Q?d. Write the genotypes of the three strains in parts a, b,and c.e. What F2 ratio is expected from crossing plants fromparts a and b? (Assume independent assortment.)
- 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 daysThe image below represents a flower meristem viewed from above. At the time the image represents, the cells are undifferentiated, although their eventual fates are determined (e.g. carpels, etc.). The rectangles indicate the regions of the meristem where particular genes (A, B, and C) are expressed. Note that these genes are expressed all around the circumference of the meristem at the location indicated; in other words, gene A is active in all cells in the rings labeled sepal and petals. Sepals Petals Stamens UEn Carpels Explain what cue the floral cells are likely using to determine the cells that will differentiate into the different parts (ie. sepal, petal, etc.) based on the given scenerio.The image below represents a flower meristem viewed from above.
