????美國專利法規(guī)條款規(guī)定800/302為轉(zhuǎn)基因農(nóng)作物類別：
????【網(wǎng)站原文】
????302 Insect resistant plant which is transgenic or mutant:
????This subclass is indented under subclass 298. Subject matter wherein the higher plant, seedling, plant seed, or plant part is insect resistant and has been made via a transgenic method or a mutation step。
????(1) Note. Transgenic means that new genetic information has become embedded into the germ line of the plant. A mutant plant is one wherein a change in the structure of the genetic material (i.e., the DNA base sequence) of the plant has occurred. Mutations result in heritable alterations in the genotype of the plant。
????【中文翻譯】
????302 轉(zhuǎn)基因或基因變異的抗蟲植物
????此項(xiàng)為分類298之下的一個(gè)亞類，其高等植物的種苗、植物的種子或植株任一部分之生物物質(zhì)皆具有抗蟲特性，為先前通過某一種轉(zhuǎn)基因方法或基因變異而獲得的抗蟲性狀。
????(1)注：轉(zhuǎn)基因即指在一種植物的基因序列中嵌入新的基因信息?；蜃儺惖闹参镏改骋换蛭镔|(zhì)結(jié)構(gòu)(如DNA堿基序列)發(fā)生改變的植物。突變可導(dǎo)致基因結(jié)構(gòu)改變并可遺傳至后代。
????PH4CV的類別編號(hào)包括“800/302”；在美國專利法的規(guī)定中，“302”即指“基因修飾”。長長的專利資料文件顯示，PH4CV的開發(fā)包括了使用BT和HT轉(zhuǎn)基因技術(shù)——這是用于商業(yè)化大宗農(nóng)作物的僅有的兩類轉(zhuǎn)基因技術(shù)。
????美國農(nóng)業(yè)部在核準(zhǔn)PH4CV品種的公告中指出，該品種的種植必須遵循“農(nóng)作物保護(hù)法”的要求，例如，種子必須是新的、成分穩(wěn)定的同代同樣品種，未經(jīng)批準(zhǔn)不得使用子代作為種子使用；對(duì)轉(zhuǎn)基因作物種植的要求包括“避難所”種植(在種植轉(zhuǎn)基因玉米的農(nóng)田里用一定比例的農(nóng)田種植非轉(zhuǎn)基因玉米，通常該比例為20%或更多)，必須有農(nóng)田生態(tài)及環(huán)境等各方面的跟蹤監(jiān)護(hù)。
????對(duì)轉(zhuǎn)基因問題非常關(guān)心的云南財(cái)經(jīng)大學(xué)社會(huì)與經(jīng)濟(jì)行為研究中心教授顧秀林認(rèn)為，轉(zhuǎn)過一次基因以后的作物不論經(jīng)過多少代自交，然后再做多少次雜交，也不是傳統(tǒng)意義上的雜交品種，而是轉(zhuǎn)基因品種。如果先玉335是轉(zhuǎn)過基因的，那么中國一些以先玉335為父本或母本延伸開發(fā)的玉米品種H1588和T88等等，也必須作為轉(zhuǎn)基因或含有轉(zhuǎn)基因成分的品種來管理。
????“如果是這樣的話，山西吉林等地的各種動(dòng)物異常反應(yīng)就有了比較合理的解釋，因?yàn)槭澜绺鞯鬲?dú)立試驗(yàn)均揭示轉(zhuǎn)基因食品喂養(yǎng)動(dòng)物會(huì)出現(xiàn)腎臟和肝臟損害、生殖系統(tǒng)出問題、免疫不正常，而這種大面積多地區(qū)類似的異常反應(yīng)也絕非僅僅是環(huán)境因素改變而形成，這意味著轉(zhuǎn)基因玉米正在我國進(jìn)行著實(shí)實(shí)在在的非模擬檢驗(yàn)?！币晃粯I(yè)內(nèi)人士說。
????為了查實(shí)先玉335的父本專利是否涉及轉(zhuǎn)基因，本報(bào)向先鋒良種國際有限公司發(fā)去詳細(xì)采訪函，幾次向先鋒公司詢問，但截至發(fā)稿時(shí)，尚未收到該公司的任何答復(fù)。

????Inbred maize line PH4CV
????Abstract
????An inbred maize line, designated PH4CV, the plants and seeds of inbred maize line PH4CV, methods for producing a maize plant, either inbred or hybrid, produced by crossing the inbred maize line PH4CV with another maize plant, and hybrid maize seeds and plants produced by crossing the inbred line PH4CV with another maize line or plant and to methods for producing a maize plant containing in its genetic material one or more transgenes and to the transgenic maize plants produced by that method. This invention also relates to inbred maize lines derived from inbred maize line PH4CV, to methods for producing other inbred maize lines derived from inbred maize line PH4CV and to the inbred maize lines derived by the use of those methods。
