Concept explainers
To assume: The possible explanation and control that might the researchers have used to for the given experiment.
Introduction: Transgenic plants are the plants whose genomes are altered or modified by inserting a desired foreign gene using certain genetic engineering techniques. The production of transgenic plant was intended for the expression of desired trait in the plants that does not occur naturally in them. Transgene (foreign gene) can be from unrelated origin.
Nowadays, transgenic plants play a significant role in phytoremediation (using plants to clean up the environment). The transgenic plants have the transgene, which makes the plant efficient to remove, utilize, and detoxify the pollutants. It can be used to clean up an important soil and air contaminant. Transgenic poplar plants that could express cytochrome P450 enzyme were produced to check their efficiency to clean the Trichloroethylene (TCE).

- Imagine a rocky slope in the Santa Ynez Mountains behind Santa Barbara that is covered purple sage (Salvia leucophylla) and white sage (Salvia apiana). Competition among plants is intense, and research has shown that individual plants compete for space via allelopathy. Imagine that some of the plants (the "mutants") experience a genetic mutation that renders the essential oils in their leaves much less volatile or much less abundant than the essential oils in the plants around them. The most likely outcome for these mutant plants is:arrow_forwardWhat are the for phytoglycogen confirmation properties in maize can that can determine the extracted glycogen in the plants. Present it nicely.arrow_forwardExplain on how TYR has considerable variety among vastly different species, but can also be extremely similar for closely related species. Also explain how with unlimited resources, we could sample our own data and compare healthy TYR genes with those that have mutations directly. Finally, explain on how the TYR gene plays a crucial role in the melanin biosynthesis process in organisms.arrow_forward
- Create workplan step by step on regenerating a BT maize plant selecting using phosphinothricin herbicide. Mention uses of agrobacterium , somatic embryogenesis, and construction of engineered TDNA for your workplanarrow_forwardHow can synthetic promoters alter plants system? A. Introduction of a heterologous DNA into plants directly manipulates the regulatory elements or expression of endogenous genes. B. Development of a phytosensor combined with signal transduction pathway activates signal to detect pathogens. C. Utilization of an engineered DNA - binding domains and catalytic effector results to modified signal responses.arrow_forwardIs it true or false? Indicate whether the sentence is true or false. If it's False, explain why it's so in no more than two sentences. a. ABA synthesis mutants close their stomates under drought stress to prevent water loss.b. By inhibiting ABA synthesis, harvested flowers can be kept fresh for a longer time.arrow_forward
- Describe the use of Plant Growth regulators in Agriculture give at least 4 examplesarrow_forwardPlants reproduce through various methods. Explain which method helps to create genetic variability in crop plants? Moreover elaborate mechanisms promoting self or cross pollination.arrow_forwardSuppose we are studying the genes psbA (which codes for D1), DICER1 (which nonspecifically splices mRNA transcripts), and CYCLASE1 (which codes for a protein involved in apoptosis) in plant X. Which of the following would need to occur in the cytoplasm of plant X’s leaf cell to decrease the rate of photosynthesis? Inactivation of the psbA gene. Degradation of DICER1 mRNA transcripts in the cytoplasm. Increase the amount of P680+ Increase expression of CYCLASE1. a) 1,2and3 b) 1and3 c) 2and4 d) 4 only e) All of 1, 2, 3, and 4 are correctarrow_forward
- Elaborate the advantage and disadvantages of Nano-Plant Growth Regulatorarrow_forwardCertain genetically modified tomatoes were designed to suppress (reduce the effectiveness) the enzyme polygalactias which delays ripening. How does this gene modification affect the consumer and the diet of individuals in developing countries? options: Delaying the ripening process means that the tomatoes have a longer shelf life. The tomatoes survive delivery to the consumer and provide nutritional value to more people. Delaying the ripening process means that the tomatoes can stay on the vine longer to receive nutrients. Once picked, these tomatoes will ripen rapidly to provide a full taste to the consumer. Delaying the ripening process means that the tomatoes are more likely to freeze on the vine before becoming ripe. This freezing process locks in the minerals and beneficial nutrients so that the tomato can be transported without losing its nutritional benefit. Delaying the ripening process means that the tomatoes are more likely to have a shorter shelf…arrow_forwardSimpLENI will be competing in a Lugaw Cooking Competition in May. She will be using onions as a special ingredient and garnish in her recipe. She then planted onions in two soil treatments labelled as ANGAT and UNITY. After a week, SimpLENI noticed that her onions in ANGAT increased in number compared to that of onions in UNITY. She then hypothesized that the soil treatments affected the cellular division in the roots of onions contributing to the difference in yield. To prove this, SimpLENI prepared longitudinal sections of onion root tips. Support SimpLENI in her experiment and win the competition by answering the following questions:arrow_forward
