Question
Chapter 31.3, Problem 1CC
Summary Introduction
To explain:
Why plants with mutant that produce excessive abscisic acid (ABA) are warmer than wild-types under normal, non-stressful circumstances.
Concept introduction:
ABA is a plant stress hormone that helps the plant to overcome drought conditions. It does so by helping in the closing of stomata. ABA causes water to flow out of guard cell and thus lessen its turgor. Hence, the stomata close.

What are the concepts behind osmosis and enzymatic browning in potatoes?
Due to climate change, food security is highly compromised. Sequentially explain recombinant DNA techniques you would use to isolate and transfer a heat resistant gene from a bacteria to help maize plants thrive in areas with water scarcity.
You are studying a biochemical pathway and isolate Neurospora mutants I, II, and III.Mutant I can grow if you supplement the medium with Z.Mutant II can grow if you supplement the medium with X, Y, or Z.Mutant III can grow if you supplement the medium with X and Z, but not with Y.
Draw a biochemical pathway that shows the correct order for compounds X, Y, and Z and for the enzymes that each mutant is defective for.

- Artificial leaves are beginning to be developed by biotechnology companies. Outline the basic characteristics that an artificial leaf would need to have to manufacture a sugar.arrow_forwardIn this activity you will analyze the results of experiments that investigate nutritional requirement of several mutant strains of yeast. The mutations in these strains cause a nutritional requirement for an amino acid, such that the strains will not grow in media that lack one specific amino acid. Any mutant that has a nutritional requirement is called an auxotroph, and is incapable of growing in a "minimal medium" containing only a carbon source (e.g., glucose), a simple nitrogen source (e.g., ammonium sulfate), and various salts and minerals. Such strains can be supported on a medium supplemented with only the missing nutrient or on a "rich" medium that contains amino acids, vitamins, nitrogenous bases, etc. (often in the form of an extract from yeast). The wild-type individual that can synthesize the metabolic component is a prototroph, and is capable of growth on minimal medium. The mutant strains in this activity are unable to synthesize tryptophan, lysine, or histidine; one…arrow_forwardA number of auxotrophic mutant strains were isolated from wild-type haploid Neurospora crassa. These strains responded to the addition of certain nutritional supplements to minimal culture medium either by growth (+) or no growth (0) The data from this experiment are presented in the table below. Diagram a biochemical pathway, complete with positions of intermediates, that is consistent with the data. Indicate where in the pathway each mutant strain is blocked.arrow_forward

Below are some results from the study: 6-glucosidase activity is measured as the number of transcript copies per gram soil (y axis for each experimental unit (a 2 gram scoop of soil), and the effect of soil type was analyzed via one-way (one factor) ANOVA. Figure 2: B-glucosidase activity for tillage (I), nontillage and no-cover (NC), cover crop plus herbicides (CH), and cover crops plus mower (CM) soils (F3,2=46, P 0.05 for the Tukey test).

- Assume that a series of compounds has been discovered in Neurospora. Compounds A–F appear to be intermediates in a biochemical pathway. Conversion of one intermediate to the next is controlled by enzymes that are encoded by genes. Several mutations in these genes have been identified and Neurospora strains 1–4 each contain a single mutation. Strains 1–4 are grown on minimal media supplemented with one of the compounds A–F. The ability of each strain to grow when supplemented with different compounds is shown in the table (+ = growth; o = no growth). Which biochemical pathway fits the data presented?

(So to get you started, notice the class 1 mutants—and there is only mutant in this class, which is mutant #5—won’t grow on minimal medium, but will grow if you give it substance Z. However, giving it substances, p, w, x, or y won’t help. This means that the gene that is mutated lies on the pathway in a place that the Z substances is to its right and all the other substances are to its left. The easiest next one to look at is the line with 2 pluses, and then the line with 3 pluses, and then the line with 4 pluses).arrow_forward
