Certain mutations in common wall cress (Arabidopsisthaliana) cause excess auxin production. Predict theimpact of these mutations on a plant’s phenotype.
Plant cells communicate in a variety of ways to elicit cellular responses. In the figure below the plant is responding the presence of light with the release of auxin. Auxin was first discovered for its ability to promote growth in plants. It is a plant hormone that inhibits the lengthening and stimulate the formation of lateral roots and root hairs.
(b) Explain the role that auxin has in eliciting the plant’s response.
Explain the signaling mechanism associated with auxin action

- Using purified auxin, how would you manipulate a bed of tulips to have stems that bend to the west? Place the auxin on the west side of the stem. Place the auxin on the east side of their stem. Place auxin in the soil on the west side of the plants. Water the plants with auxin.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_forwardSome plant hormones oppose the effect of each other. Auxins and cytokinins for example. Whereas auxins prevent shoots from branching, cytokinins promote the development of branches. What other hormones also exhibit such opposing effects?
