Question
Chapter 38.3, Problem 2R
Summary Introduction
To review:
The types of genes that can be added to the genomes of the crop plants to increase their salt tolerance and the functioning of these genes to tolerate high concentrations of salt.
Introduction:
High salt concentration in the environment has become a global problem as due to the high amount of NaCl (sodium chloride) various enzymes in plants are inhibited. Also, the protein synthesis is inhibited in these plants due to sodium toxicity. To increase the tolerance of plants against this increased soil concentration, certain genes are introduced in these plants.

Genetic variation is indispensable for crop improvement. Discuss how heritable variation can be generated in crop plants?
Rice is a staple food in Asia. In the 1950s, Asia faced food shortages and an impending famine. If you have relatives that lived in Asia during the ’50s and ’60s, they may tell you that due to the rice shortage, many starved and those who were lucky had to supplement their diet with other crops, such as barley. In 1962, an organization focused on research and development of rice called the International Rice Research Institute (IRRI) developed a high-yielding variety of rice by crossing the two types of rice from Indonesia and China. The result was groundbreaking. The new variety called IR8 (India Rice 8) increased its yield as much as 10 times the traditional variety of rice. By the early 1970s, many rice farmers in India, the Philippines, and Vietnam switched to cultivating IR8 rice, making these countries into major rice exporters, preventing a mass famine in Asia, and saving millions of lives.
In many major Canadian cities, a GMO-free, organic diet is becoming more popular, as can…
In most parts of the world, commercial potato crops are produced asexually by planting tubers. However, in some regions of the world, such as Southeast Asia and the Andes, some potatoes are grown from true seeds. Discuss the advantages and disadvantages of growing potatoes from true seed.

I set up several treatments where some plants get no salt, some are watered with a 0.05% salt solution, and some are watered with a 0.1% salt solution. I use the same species of plants, the same soil, and the same total amounts of water in my experiment. Every other day I record the height of the plants in cm.

The scientific name of a pinto bean is Phaseolus vulgaris. Pinto beans are kind of beans people usually eating, and people commonly use pinto beans in many dishes, such as rice and pasta. Planting pinto beans need many necessary factors, however, I think the type of soil is the most important one to grow it faster. Pinto beans are kind of plants can grow in dark and dry area, so even in dark (less light), they can grow as well. The goal is to determine that soils have different characteristics that can help or hurt plant growth. In order to discover the effects soils have on plant growth, three different soil samples will be used in a controlled study. The samples will vary in consistency, texture, color, location, moisture, and contact with human life to ensure that the samples are…arrow_forward
