Question
Chapter 36, Problem 11TYK
Summary Introduction
To review:
The use of tissue culture to propagate a large number of pest-resistant petunia plants.
Introduction:
The techniques utilized in maintaining or growing cells, tissues, or organs of plants in a controlled environment is plant tissue culture. Cultures are usually performed under sterile conditions and on a culture medium with a control composition. This technique is often used for crop improvement. This is done by producing better variants, which can be superior in nutrient value, stress resistant, or disease resistant.

Background: Boll weevil is a serious pest of cotton crop. Effective control involves applications of chemical insecticides, increasing the cost of production and environmental pollution. The current genetically modified Bt crops have allowed great benefits to farmers but show activity limited to lepidopteran pests. This work reports on procedures adopted for integration and expression of a cry transgene conferring resistance to boll weevil and fall armyworm by using molecular tools. Four Brazilian cotton cultivars were microinjected with a minimal linear cassette generating 1248 putative lines. Complete gene integration was found in only one line (TO-34) containing one copy of crylla detected by Southern blot. Protein was expressed in high concentration at 45 days after emergence (dae), decreasing by approximately 50% at 90 dae. Toxicity of the cry protein was demonstrated in feeding bioassays…arrow_forwardUse the information provided in the experiment below to annotate/ label the figure.
