Chapter 37, Problem 3ITD
Summary Introduction
To review:
The reason for no overlapping between up and down bubble for each hormone.
Introduction:
In the given study, auxin and brassinosteroids are studied as the plant growth regulating hormones in Arabidopsis seed. A Venn diagram is used for representing the degree of overlap of auxin-responsive and BR-responsive genes, and the relative proportion of the two genes. In this case, the genes observed for the response of the two phytohormones are Yucca genes.

Green fluorescent protein (GFP) can attach and mark other proteins with fluorescence, enabling scientists to see the presence of a particular protein. In an experiment to understand the molecular physiology behind the GA-induced seed germination, a GFP-tagged protein was observed to be moving from the cytoplasm into the nucleus of aleurone layer cells before the detection of alpha-amylase in the endosperm. Based on your knowledge, identify the possible protein(s) with which the GFP is attached in the given situation. Justify your answer.
1.
A) Describe the three steps (Reception, Transduction, Response) of de-etiolation (greening response) signal transduction in plants.
B) Describe a signal transduction (give the stimulus and response) that may occur in humans.

b. If the plants used gametophytic self-incompatibility, half of the pollen would be successful.
c. If the plants used sporophytic self-incompatibility, half of the pollen would be successful.
d. Pollen from an S2S5 plant can never pollinate an S1S5 flower.

- Many different treatments were possible in the phototropism experiment. Based on your understanding of phototropism, provide predictions about the direction of plant growth for the following two scenarios, and explain your reasoning. 1. The tip of the coleoptile is removed and lanolin with auxin is applied to the dark side of the stem. 2. The tip of the coleoptile is removed and lanolin with auxin is applied to the light side of the stem.arrow_forwardThe data that is attached below was collected during a lettuce seed ecotoxicity assay. Lettuce seed assays are used to compare the ecotoxicity of methanol, ethanol, and isopropanol by these alcohols' effects on germination rate and root elongination. Using the attached data, help answer which alcohol seems to be the most toxic to lettuce seeds. Why or why not would your results be expected? What does this information tell you about using ecotoxicity data to estimate human toxicity?arrow_forwardUsing the provided figure, describe the importance of the two phytochrome systems in controlling de-etiolation and green stem elongation under full sun and shade.

- A group of students have carried out an experiment to investigate the relationship between the amount of growth hormone BAP in the culture medium and the growth of shoot.They have supplemented the medium with 4 different concentration of growth hormone which is (1 mg/L ,2 mg/L BAP,3 mg/L 4 mg/L) of BAP.According to the result after eight weeks, BAP at 2 mg/L had given better response with respect to shoot induction, shoot multiplication, length of shoot, and number of leaves per explants when compare with other amount of BAP. Discuss why?arrow_forwardThis is a picture of the initial experiments to figure out how auxin and phototropism worked. How do you expect the plant will grow in each scenario and why?arrow_forwardThe 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.arrow_forward
