without human help; the kernels will stay firmly attached to the cob and rot. This does not represent a useful adaptation for the species, but is excellent for harvesting and transporting corn. GBS (genotyping-by-sequencing) technology helps the corn industry by allowing for a better understanding of the genetic mechanisms of which kind of corn should be planted, where they should be planted, and how much should be planted. The main areas of success include: low cost, reduced samples, fewer CPR and purification steps, no size fractionation, and more. This makes the production of corn much easier. Florida oranges Citrus has been a major commercial product in Florida since the 19th century. Florida produces over 70% of the U.S. citrus supply. The color of oranges is not related to ripening, but is a serious component for sales. The orange color only develops in areas with cool nighttime temperatures. In tropical climates, growers often expose the fruit to ethylene, to promote the loss of chlorophyll and expose the beta-carotenes (the orange color). North American apples Apples are not native to North America, but today the North American continent boasts the greatest diversity of apples in the world. Part of this is due to "Johnny Appleseed," real name John Chapman. Chapman spent 48 years travelling all along the American northwest spreading apple seeds and planting trees. While apples come in literally thousands of varieties, the majority of the apple market is based on three: Red Delicious, Golden Delicious, and Granny Smith. Ornamental plants Ornamental plants can be found in almost any store, and many people have at least one in their home. However, ornamental plants are not limited to houseplants. Landscaping agencies make heavy use of ornamental plants, usually with an accompanying high cost. Trees, shrubs, flowers, and grasses, all of these are planted by professional landscaping agencies regularly, with a large economic effect. Carnation Carnation is popular because of its color, size, fragrance and longevity. Scientists studied the biological processes, cellular component and molecular functions to improve the growing of carnation flowers. Carnations grow better in cool climate around 10 to 15 degrees Celsius. Scientists tried to improve the cut flowers to "live" longer in higher temperatures. It turned out that carnations can't grow well in hot environments. So, the farmers plant the carnations in greenhouses to assure that they are growing. Crape myrtle Crape myrtles (Lagerstroemia spp. L) are very common
