1 Brief history of sugar beet
The first references to the family of plants known as “Beta” can be found in Greek literature around 420BC. They were described as garden plants; dark and light varieties are mentioned. Sugar beet was first grown 2000 years ago originally for its leaves, which were probably the spinach or swiss chard of their day. Beet gradually spread throughout France and Spain, often in monasteries but also by peasant farmers. By the fifteenth century beet was grown all over Europe. The vegetable was probably selected from various Beta species growing around the shores of the Mediterranean. It was widely used for culinary purposes in Europe from the middle Ages onwards.
The sugar beet currently grown is far removed from the garden plant. Later the root became a popular vegetable, especially the red type of beet known as beetroot. In the second half of the eighteenth century the chemist Marggraf demonstrated that the sweet tasting crystals obtained from juice of beets and sugar cane were similar, this was the first step in developing beets into an industrial crop for extraction of sugar. Before that time nobody paid much attention to what gave the roots their sweetness. Beets with higher levels of sucrose were selected from a white fodder beet variety. The White Silesian variety is still considered to be the primary source of sugar beet germplasm grown today (Fischer 1989).
The plant Beta vulgaris has been developed to fill the need for a sugar crop that could be grown in temperate climates. Today the sugar beet crop is grown in Europe, Asia, North Africa, North America and even in some parts of South America .The sugar beet was the source of only 5% of the world's commercial sugar in 1840, but by 1890 it supplied ...

...cardi, Lewellen et al. 2002). This resistance was recognized as monogenic and dominant as hybrids produced segregated in a pattern typical of a single dominant gene, Rz1. (Rz2) was identified in a sea beet population coded WB42 (Scholten and Lange 2000).
Progress in molecular genetics during the last century has permitted greater characterization and understanding of gene function, which will ultimately enable advances in classical breeding. New disease resistance, and other desirable genes will be identified in Beta germplasm screening studies, and introduced into breeding lines and into commercial cultivars (Francis and Luterbacher 2003). As a result, the molecular genetics could result in truly high yielding, low-input, and pesticide free sugar beet cultivation. This would be beneficial both to the environment and, depending on the seed price, to growers’ income.
The beet Lab experiment was tested to examine bio-membranes and the amount of betacyanin extracted from the beets. The betacyanin is a reddish color because it transmits wavelengths in red color and absorbs most other colors. The membrane is composed of a phospholipid bilayer with proteins embedded in it. The phospholipid bilayer forms a barrier that is impermeable to many substances like large hydrophilic molecules. The cells of beets are red and have large vacuoles that play a big role for the reddish pigment. This experiment aimed to answer the question, “How do cell membranes work?” The hypothesis we aim to test is: Cell membranes work as a fluid mosaic bilayer of phospholipids with many embedded proteins. We predicted that the 50% Acetone will break down the most betacyanin. Our hypothesis was proven wrong by our data collected. We could test our predictions by doing the experiment multiple times and compare the
In document 7a, it tells when sugar got attention worldwide rich people started moving to the West Indies to grow because everyone wanted sugar and sugar makes you a lot of money. The more you consume sugar, the more you will start to
Along with an exuberance of gold and silver, plants such as corn, tobacco, potatoes, tomatoes, chocolate, sugar, and myriad other fruits and vegetables were introduced into European diets. The humble potato was especially adopted by the Irish; Tomatoes, the Spanish; and tobacco, the entire world. Due to the increased food supply, the European population exploded and necessitated the subsequent settlement of the ‘New World’.
Modern biotechnology was born at the hands of American scientists Herb Boyer and Stain Cohen, when they developed “recombinant deoxyribonucleotide, (rDNA), [1] for medicinal purposes. Subsequently, biotechnologists started genetically engineering agricultural plants using this technology. A single gene responsible for a certain trait, from one organism (usually a bacterium) is selected altered and then ‘spliced” into the DNA of a plant to create an agricultural crop consisting of that...
Suprisingly, for something so desireable knowledge of sugar cane spread vey slow. First found in Guinea and first farmed in India (sources vary on this), knowledge of it would only arrive in Europe thousands of years later. However, there is more to the history of sugar cane than a simple story of how something was adopted piecemeal into various cultures. Rather the history of sugar, with regards to this question, really only takes off with its introduction to Europe. First exposed to the delights of sugar cane during the crusades, Europeans quickly acquired a taste for this sweet substance.
The rapid growth of sugar as a food has a long and intertwining history that originated in New Guinea. Following the production, consumption, and power that corresponds with sugar, one is able to see numerous causes and effects of the changes underway in the world between 1450 and 1750. The production of sugar in the Americas eventually led to not only the creation of the Atlantic Slave Trade, but also enhanced commerce. Consumption of sugar through rapid trade thoroughly helped to develop modern capitalism. The power that sugar generated dramatically changed the economic, social, and political fate of the nation as a whole.
In an argument, the lawyer representing Monsanto Company stated that the amount of arable land around the world is quickly dwindling. This means that it is time to take extra drastic measures to improve food safety throughout the world. Genetically modified seeds and related chemicals offer the best solution for such food safety concerns and thus the company was right to make such investments. This idea comes from recent realization of a robust population boom throughout the world, an inability for traditional agricultural practices and seeds to withstand changing climatic systems. Modification of the seed’s genetic material to withstand climatic and other environmental threats seems to be a viable solution to the challenge.
Sugar was first grown in New Guinea around 9000 years ago, which New guinea traders trade cane stalks to different parts of the world. In the New world christopher columbus introduced cane sugar to caribbean islands. At first sugar was unknown in Europe but was changed when sugar trade first began. Sugar trade was driven by the factors of production land which provided all natural resources labor what provided human resources for work and capital which includes all the factories and the money that’s used to buy land. Consumer demand was why sugar trade continued to increase.
Originally, sugar started in Southwest Asia and made its way to the New World by Christopher Columbus in 1492. He started to grow it in this new tropical environment and the plant grew rapidly. Due to the success of this plant, other colonies wanted to get their hands on it. The colonists spread the plant out to the European colonies, Spanish colonies, and the Portuguese brought sugar to Brazil. Sugar made its way all around the world.
Despite the federal aid granted to sugar growers, not all sectors of agriculture devoted to growing sugar derivatives flourished. Domestic production of sugar cane increased steadily from 1982 onward, while sugar beet production stagnated (Knutson, 1985). Through time, the largest number of sugar beet farmers were concentrated in a specific West/Midwest region of the U.S. (Minnesota, North Dakota, Idaho) while sugar cane farmers were found in the Southeast, specifically Louisiana and Florida.
When asked the question, “What was the most significant revolution in history?” to an English speaker, most people would respond with a political revolution such as the French Revolution, American Revolution, or the Russian Revolution. A few people would respond with other revolutions such as the Industrial Revolution, the Renaissance, or the Reformation. The commonality between all of the revolutions listed above is that all revolutions have resulted in direct changes in the Western World. This is a result of ethnocentrism, considering one’s culture to be superior to others. However, there are many revolutions that have occurred mostly outside of Europe. An example would be the Sugar Revolution, “a series of interrelated changes that altered
The beetroot contains a red pigment that is kept in the cells by the membranes. If the membranes are damaged, the pigment “betalain” will leek out.

Agriculture has been around for about 11,000 years. Around 9.500 BC, the first signs of crops began to show up around the coastlines of the Mediterranean. Emmer and einkorn wheat were the first crops that started to show up in this area, with barley, peas, lentils, chick peas, and flax following shortly. For the most part, everyone was a nomad and just travelled along with where a herd went. This went on until around 7.000 BC, and then the first signs of sowing and harvesting appeared in Mesopotamia. In the first ...
