Ⅳ 轉基因技術的發展前景及取得的成就

轉基因食品前景樂觀 雖然對於轉基因食品還存在這樣那樣的爭論，但它的優勢還是表現得越來越顯著。在美國得到普遍種植的轉基因玉米中色氨酸含量提高了20％。色氨酸是人體必需的氨基酸，無法自己合成，只能從外界攝取，一般植物性食品中色氨酸含量很低甚至沒有，只有靠動物性食物中獲取，轉基因玉米的出現，對於素食主義者而言，無疑是個喜訊。轉基因油菜，不飽和脂肪酸的含量大增，對心血管有利。轉基因工程牛奶，增加了乳鐵蛋白、抗病因子的含量，降低了脂肪含量…… 西方發達國家已充分認識到轉基因食品的發展前景，並注入大量資金。盡管大多數英國人反對轉基因食品，但該國超過7000種的嬰兒食品、巧克力、麵包、香腸等日用品，可能含有經過基因改造的大豆副產品，而且英國政府對轉基因食品的研究非常支持，布萊爾首相就是轉基因食品的推崇者。 在我國，人多地少狀況突出，基因工程是解決糧食產量、提高糧食質量的重要途徑。近年來，我國轉基因食品的研究有了長足的進步，目前的研究開發居世界中等水平，僅次於美國和加拿大。羅教授認為，隨著轉基因食品商業化的步伐不斷加快，轉基因食品必將成為人們餐桌上的美味佳餚。 全球轉基因技術研究與應用情況 自1996年首例轉基因農作物產業化應用以來，全球轉基因技術研究與產業應用快速發展。發達國家紛紛把發展轉基因技術作為搶占未來科技制高點和增強農業國際競爭力的戰略重點，發展中國家也積極跟進，並呈現以下發展態勢： 一是品種培育速度加快。隨著生命科學、基因組學、信息學等學科的發展，轉基因技術研究日新月異，研究手段、裝備水平不斷提高，基因克隆技術突飛猛進，一些新基因、新性狀和新產品不斷涌現。品種培育呈代際特徵，目前全球轉基因生物新品種已從抗蟲和抗除草劑等第一代產品，向改善營養品質和提高產量的第二代產品，以及工業、醫葯和生物反應器等第三代產品轉變，多基因聚合的復合性狀正成為轉基因技術研究與應用的重點。 二是產業化應用規模迅速擴大。截至2009年底，全球已有25個國家批准了24種轉基因作物的商業化應用。以轉基因大豆、棉花、玉米、油菜為代表的轉基因作物種植面積，由1996年的2550萬畝發展到2009年的20億畝，14年間增長了79倍。美國仍然是最大的種植國，2009年種植面積9.6億畝；其次是巴西，3.21億畝；阿根廷，3.195億畝；印度，1.26億畝；加拿大，1.23億畝；中國，5550萬畝；巴拉圭，3300萬畝；南非，3150萬畝。值得一提的是，2000年以來，美國先後批准了6個抗除草劑和葯用轉基因水稻、伊朗批准了1個轉基因抗蟲水稻商業化種植；加拿大、墨西哥、澳大利亞、哥倫比亞4國批准了轉基因水稻進口，允許食用。 三是生態和經濟效益十分顯著。1996至2007年，全球轉基因作物的累計收益高達440億美元，累計減少殺蟲劑使用35.9萬噸。2008年，全球轉基因產品市場價值達到75億美元。

Ⅳ 關於轉基因的英語作文怎麼寫

Genetically modified food
轉基因食品
Attack of the really quite likeable tomatoes
招人喜愛的西紅柿遭攻擊
The success of genetically modified crops provides opportunities to win over their critics
轉基因作物的成功為說服其批評者提供了機遇。

Feb 25th 2010 | From The Economist print edition
IN THE 14 years since the first genetically modified crops were planted commercially, their descendants, relatives and remixes have gone forth and multiplied like profitable, high-tech pondweed. A new report (see article) shows that 25 countries now grow GM crops, with the total area under cultivation now larger than Peru. Three-quarters of the farmland used to grow soya is now sown with a genetically modified variant, and the figures for cotton are not that far behind, thanks to its success in India. China recently gave the safety go-ahead to its first GM rice variety and a new GM maize that should make better pig feed. More and more plants are having their genomes sequenced: a full sequence for maize was published late last year, the soya genome in January. Techniques for altering genomes are moving ahead almost as fast as the genomes themselves are stacking up, and new crops with more than one added trait are coming to market.
Such stories of success will strike fear into some hearts, and not only in GM-averse Europe; a GM backlash is under way in India, focused on insect-resistant aubergines. Some of these fears are understandable, but lacking supporting evidence they have never been compelling. On safety, the fear which cuts closest to home, the record continues to look good. Governments need to keep testing and monitoring, but that may be becoming easier. More precise modifications, and better technologies for monitoring stray DNA both within plants and in the environment around them, mean that it is getting easier to be sure that nothing untoward is going on.
自轉基因首次走向市場的14年中，它們的後代、類似品種以及雜交品種不斷出現並增多如可獲利的高科技水池草。一份新出的報告顯示，目前已有25個國家種植轉基因作物，正在培植的作物的面積比秘魯的面積還要大。曾經種植大豆的四分之三的農田現在都用於種植轉基因品種，用於種植棉花的農田面積也並非遠遠落後，因為它在印度很受歡迎。最近中國確保種植其首個轉基因品種和新開發的轉基因玉米，這必將給豬帶來更好的飼料。越來越多作物的基因序列得到確定，玉米的整個序列在去年年末公布了，大豆的基因在1月份也公布了。技術改變基因的速度與基因自身重組的速度相當，具有多種其它特性的新品種正向市場進發。
這種成功的報道將使一些人擔心，這種擔心不僅僅出現在反對轉基因作物的歐洲。轉基因作物在印度也遭到強烈的反對，主要集中反對抗蟲茄子。其中的一些擔心可以理解，但是缺乏可靠證據，它們從來就沒有說服力。在安全方面，這種擔心與家庭的關系最密切，所作的記錄還是表明是好的。政府需要不斷試驗和監控，不過這或許正變得更加簡單。更加精確的改良和更加先進的監控作物及其環境中的游離的DNA的技術意味著更加容易保證不出現異常現象。
Then there is the worry that GM crops are a way for big companies to take over the livelihoods of small farmers and, in the end, a chunk of nature itself. Seen in this light the fact that 90% of the farmers growing GM crops are comparatively poor and in developing countries is sinister, not salutary; given Monsanto』s dominance in America』s soyabean market, it seems to suggest incipient world domination. It is certainly true that big firms make a lot of money selling GM seeds: the GM seed market was worth $10.5 billion in 2009, and the crops that grew from that seed were worth over $130 billion. But multinationals are not the only game in town. The governments of China (which has increased agricultural research across the board), India and Brazil are also developing new GM crops. In 2009 a GM version of an Indian cotton variety, developed in the public sector, came to market, and a variety engineered by a private Indian firm has been approved for commercialisation. Charities, such as the Bill and Melinda Gates Foundation, are also funding efforts in various countries to make crops more hardy or nutritious. GM seeds that come from government research bodies, or from local firms, may not arouse quite so much opposition as those from large foreign companies, especially when they provide characteristics that make crops better, not just easier to farm.
還有一種擔心，就是轉基因作物是大公司剝奪小農生計的一種方法，最終也會破壞大自然本身。從這種角度看，轉基因作物的90%的農民都相對較貧窮，都來自發展中國家是有害的，而不是有益的。Monsanto支配著美國的大豆市場，這似乎暗示著初步支配了世界。大公司通過出售轉基因種子可以賺取很多錢，這顯然是事實：2009年，轉基因種子市場的銷售額為105億美元，而這些種子種出的作物價值為1300億美元。中國（在全國加強農業研究）、印度和巴西政府也在開發新的轉基因作物。2009年，公共部門開發的印度棉花品種的轉基因品種走向了市場，有印度一家私營公司研製的品種已經批准用於商業。如比爾梅琳達蓋茨基金會等慈善機構也在為多國的努力提高資金，讓作物更加的強壯或更加具有營養價值。尤其當他們的品種具有的特性可以使作物更好，而不僅僅是更容易種植時，來自政府研究機構或當地公司的轉基因種子或許不會像來自大型外國公司一樣遭到很多反對。
Moreover, where the seeds come from is a separate question from who should pay for them, as Mr Gates points out. As with drugs and vaccines, it is possible to get procts that were developed with profit in mind to the people who need them using donor money and clever pricing and licensing deals. In the longer term, if the seeds deliver what the farmers require, the need for such special measures should diminish. After all, the whole idea is not that poor farmers should go on being poor. It is that poor farmers should get a bit richer, be able to invest a bit more, and thus increase the food available to a growing and predominantly urban population.
此外，正如蓋茨指出的那樣，種子的來源和誰購買它們是兩個問題。正如葯物和疫苗一樣，通過使用捐款者的錢以合理的價格和經許可的協議可以獲得產品，這些產品本是以獲利為目的而為那些需要它們的人研製的。從長遠來說，如果這些種子正是農民們需要的，這種特殊的措施就都沒必要了。畢竟，整個理念並不是貧窮的農民必須要繼續貧窮，而是貧窮的農民必須要富一點起來，能夠多投資點，這樣糧食才能滿足日益增長和以城市人口為主的人口的需要。
More than strange fruits
不僅僅是奇怪的水果
There is another worry about GM technology, though, that should be taken seriously. It is that its success and appeal to technophiles may, in the minds of those who pay for agricultural research, crowd out other approaches to improving farming. Because it depends on intellectual property that can be protected, GM is ripe for private investment. There is a lot of other agricultural research that is less amenable to corporate ownership but still needs doing. From soil management to weather forecasts to the preservation, study and use of agricultural biodiversity, there are many ways to improve the agricultural systems on which the world』s food supply depends, and make them more resilient as well as more profitable. A farm is not a just a clever crop: it is an ecosystem managed with intelligence. GM crops have a great role to play in that development, but they are only a part of the whole.
必須嚴肅對待另一種對轉基因技術的擔憂。轉基因作物的成功以及新科技迷對此技術很感興趣，那些為農業研究提供資金的人可能不會再想其它方法改善種植情況。因為知識產權會受到保護，私人投資轉基因作物的機會已經成熟。其它很多農業研究都不那麼適合公司掌控，但仍然需要進行。從土壤管理、天氣預測到農業生物多樣性的保護、研究和利用很多領域，改善農業系統還有很多途徑，世界的糧食供應都要依靠農業系統，因此要使它們更加富有活力，產出更多利潤。一塊農田不僅是一種高產的莊稼：它是需要人為管理的生態系統。轉基因作物在這個方向上有很好的發展前景，但它們只是其中的一部分。

Ⅶ 轉基因技術的發展與未來閱讀短文

轉基因技術是將人工分離和修飾過的基因導入到生物體基因組中，由於導入基因的表達，引起生物體的性狀的可遺傳的修飾，這一技術稱之為轉基因技術（Transgene technology）。人們常說的"遺傳工程"、"基因工程"、"遺傳轉化"均為轉基因的同義詞。
轉基因技術，包括外源基因的克隆、表達載體、受體細胞，以及轉基因途徑等，外源基因的人工合成技術、基因調控網路的人工設計發展，導致了21世紀的轉基因技術將走向轉基因系統生物技術 -2000年國際上重新提出合成生物學概念，並定義為基於系統生物學原理的基因工程與轉基因技術。
從人類耕種作物以來，我們的祖先就從未停止過作物的遺傳改良。過去的幾千年裡農作物改良的方式主要是對自然突變產生的優良基因和重組體的選擇和利用，通過隨機和自然的方式來積累優良基因。遺傳學創立後近百年的動植物育種則是採用人工雜交的方法，進行優良基因的重組和外源基因的導入而實現遺傳改良。
雖然轉基因食品與普通食品在口感上沒有多大差別，但轉基因的植物、動物有明顯的優勢：優質高產、抗蟲、抗病毒、抗除草劑、改良品質、抗逆境生存等。
轉基因產品對現實生活的影響仍然還有諸多疑問：到目前為止，我們還沒有看到有對其產品成份的詳細化驗結果和長期的安全跟蹤研究數據面試，三聚氰胺已經是最好的例子。我們不能只關注其產品的產量、外觀，應更多的研究其內在究竟包含的是什麼？抗病蟲害的原理是什麼？從生態學的角度來說，轉基因後的作物本身已經是對立生物的天敵，而其它生物的存在是大自然對生態系統的自我平衡。希望人類以及科學家們、利益集團們慎重對待轉基因技術和其產品。

Ⅷ 什麼是轉基因 閱讀答案

轉基因技術 的理論基礎來源於進化論衍生來的分子生物學。基因片段的來源可以是提取特定生物體基因組中所需要的目的基因，也可以是人工合成指定序列的DNA片段。DNA片段被轉入特定生物中，與其本身的基因組進行重組，再從重組體中進行數代的人工選育，從而獲得具有穩定表現特定的遺傳性狀的個體。該技術可以使重組生物增加人們所期望的新性狀，培育出新品種。
