Volatile Secondary Metabolites in Plant Stress Responses In 2007, researchers Casey Delphia, Mark Mescher, and Consuelo De Moraes (pictured at left) published a study on the production of different volatile chemicals by tobacco plants in response to predation by two types of insects: western flower thrips and tobacco budworms. Their results are shown in FIGURE 30.20.

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 of jckplant.They have supplemented the medium with BAP but there is another student suggested that hundred percent shooting efficiency will be obtained when the the culture media is suplemented BAP and NAA.From your point of view, state which option will you choose and explain why?
Assume that two pigments, red and bluc, mix to give the normal purple color of petunia petals. Separate biochemical pathways
synthesize the two pigments, as shown in pathways I and Il in the accompanying diagram. "White" refers to compounds that are
not pigments (total lack of pigment results in a white petal). Red pigment forms from a yellow intermediate that is normally at a
concentration loo kow to color petals. Bluc mixed with yellow makes green. Assume that no mutations are lethal.

A third pathway, whose compoundk do not contribute pelal pigmentation, normally docs not allfect the bluc and red pathways.
However, if one of its intermediates (white3) should build up in concentration, it can be converted into the ycllow intermediate of
the red pathway. In the diagram, the letiers A through E represent enzymes. The enzymes' correspoonding genes, all of which are

- Bruce Ames and his colleagues have pointed out that although detailed toxicological analysis has been conducted on synthetic chemicals, almost no information is available about the mutagenic or carcinogenic effects of the toxins produced by plants as a natural defense against fungi, insects, and animal predators. Tens of thousands of such compounds have been discovered, and he estimates that in the United States adults eat about 1.5 g of these compounds each daylevels that are approximately 10,000 times higher than those of the synthetic pesticides present in the diet. For example, cabbage contains 49 natural pesticides and metabolites, and only a few of these have been tested for their carcinogenic and mutagenic effects. a. With the introduction of new foods into the U.S. diet over the last 200 years (mangoes, kiwi fruit, tomatoes, and so forth), has there been enough time for humans to develop resistance to the mutagenic effects of the toxins present in those foods? b. The natural pesticides present in plants constitute more than 99% of the toxins we eat. Should diet planning, especially for vegetarians, take into account the doses of toxins present in the diet?arrow_forwardVolatile Secondary Metabolites in Plant Stress Responses In 2007, researchers Casey Delphia, Mark Mescher, and Consuelo De Moraes (pictured at left) published a study on the production of different volatile chemicals by tobacco plants in response to predation by two types of insects: western flower thrips and tobacco budworms.

Eng. 833 012014 STATE THE HYPOTHESIS (In if-then format): Plants, when extracted, can produce dyes and the extracts have been used for different purposes such as the textile or food industry [1]. One potential plant that can be used as a natural dye is dragon fruit (Hylocereus cacti) or by another name Pitaya. Wybraniec and coworkers reported that dragon fruit has a potential as a source to produce red pigment and it's called betalains [2]. Betalain is a water-soluble pigment that gives color to flowers and fruits. Betalain pigments are divided into two groups, namely betacyanin which produces purplish red and betaxanthin which produce yellow-orange colors [2, 3]. In the dragon fruit peel, it is also containing pigments which are usually only discarded as food waste and have not been used optimally. This is very unfortunate because the fruit of the dragon fruit itself has…arrow_forward
