1247040 五、發明說明(1) 發明領域 本發明係關於植物基因工程方法,用以改變植物種子 的成份。更具體而言,本發明係關於從亞麻獲得的發動基 因,可以引導非本生性基因在亞麻子以及其他植物種子内 的表現。 發明背景1247040 V. INSTRUCTIONS (1) Field of the Invention The present invention relates to plant genetic engineering methods for altering the composition of plant seeds. More specifically, the present invention relates to the priming gene obtained from flax, which can direct the expression of non-native genes in linseed and other plant seeds. Background of the invention
亞麻子(Linum usitatissimum)為商業上重要的含油 種子作物。又一經濟上重大原料的亞麻纖維,可從植物莖 得之。亞麻油份是用於非食用目的,例如製造清漆和油漆 ,近來更適用於製造一些食用品,諸如人造奶油、沙拉油 和調味品,因為栽培出麵為L i π ο 1 a的新品種之故(G r e e η (1986), Can. J· Plant Sci·, 66 : 499-503)。亞麻粉主 要用做反剪動物飼料成份,而亞麻纖維用來製造亞麻布。 做為原料來源的經濟重要性,需進一步改進和多樣化可行 之亞麻栽培品種的投資組合,關於農藝效益,例如種子產 率,對病原體和低溫的抵抗性,以及關於原料的產率和品 質,以適合下游應用。雖然由開發L i no 1 a栽培品種可以證 明,透過習知植物培育,可得改良亞麻栽培品種,但開發 優秀的農藝植物路線,由於涉及長期時間,在植物培育方 面需要大量投資。植物基因工程科技得以從無關的種類, 直接分離出基因,把此等基因轉移到優秀農藝背景,因而 大為減少開發新栽培品種所需時間。此外,植勿基因工程 得以製造從亞麻無法天然取得的產品,例如治療劑。 為了透過植物基因工程開發新穎亞麻栽培品種,其關Linum usitatissimum is a commercially important oilseed crop. Another economically important raw material for flax fiber can be obtained from plant stems. Linseed oil is used for non-food purposes, such as the manufacture of varnishes and paints, and has recently been more suitable for the manufacture of some food products, such as margarine, salad oil and condiments, because of the new variety cultivated as L i π ο 1 a Therefore (Gree η (1986), Can. J. Plant Sci·, 66: 499-503). Flax is mainly used as a component of the anti-shear animal feed, while flax fiber is used to make linen. As an economically important source of raw materials, there is a need to further improve and diversify the portfolio of viable flax cultivars, on agronomic benefits such as seed yield, resistance to pathogens and low temperatures, and on the yield and quality of raw materials, To suit downstream applications. Although it has been proved by the development of the L i no 1 a cultivar, the improved flax cultivar can be obtained through the cultivation of conventional plants, but the development of an excellent agronomic plant route requires a large investment in plant cultivation due to the long-term involvement. Plant genetic engineering technology has been able to directly isolate genes from unrelated species and transfer these genes to an agronomic background, thus greatly reducing the time required to develop new cultivars. In addition, plant genetic engineering can produce products that are not naturally available from flax, such as therapeutic agents. In order to develop novel flax cultivars through plant genetic engineering,

On the other hand, the performance of pharmaceutical proteins preferably requires high levels of leaf colony performance when plant leaves are harvested (see, for example, U.S. Patent No. 5,9,29,304) for manipulation of non-native genes. Performance characteristics, there are many factors that will be affected One of the factors is the selection of the transcriptional genes used. Currently, a wide range of plant-compatible mobilization genes are available, some of which are preferably recorded genes, including constitutive genes, such as the 35-S CaMV mobilization gene (Rothstein et al. (1 987), Gene 53 : 1 53- 1 6 1 ), the Genes of Genes (US Patent No. 5, 614, 399), organizes special genes, such as seed-specific genes, such as the bean sprouting genes ( Sengupta_ 6〇口31311等人 (1 985 ), “8 118 people 8 2:3 32 0-33 24), and induced genes, such as heat-induced (Czarnencka et al.

Natl. Acad. Sci. USA 88(16): 7766-7270). Other factors that can be manipulated to control the performance characteristics of non-native genes in plants, Contains transcriptional engineering factors such as intragenic regions, polyadenylation sites, and transcription termination sites

The performance characteristics of non-native genes are in turn influenced by factors that influence translation, such as the binding of nucleic acid saccharide bodies, and the skew of the code displayed by the host. In addition, the non-native gene itself affects the vitality of the transformed plant, and is therefore particularly limited to the level of performance available. This problem can be overcome in a number of situations, using special means within the tissue, such as leaves or seeds, to express proteins, or to limit the accumulation of proteins in different subcellular compartments, such as cytoplasm, internal cytoplasmic cytoplasmic cytoplasmic cytoplasmic cytoplasmic cytoplasmic cytoplasmic cytoplasmic cytoplasmic cytoplasmic cytoplasmic cytoplasm Typically, it is in the presence or absence of a particular target sequence that directs the protein to such intervals. Another factor that affects performance characteristics is where the structure itself is attached to the host stain. This effect can be used to illustrate how the different plants will behave in a fluctuating level when they are transformed in the same recombinant structure.
盡本發明人等所知,非本生性基因在亞麻子内的表現 ,只載於PCT植物專利申請案W0 98/ 1 8948號内。此案揭示 從亞麻衍生的兩種硬脂醯-醯基載體蛋白質稀化酵素(SAD) 基因。相關的SAD發動基因序列,可用於改造亞麻和其他 植物,以表現内生或外來基因。然而,W0 98/ 1 8948教示 的方法受到事實的限制,因為SAD發動基因在亞麻内無種 子特殊性,會賦予對葉、莖、花、種子的表現。非本生性 基因的表現,即會在非種子組織内造成不良的副作用。此 外,使用SAD發動基因,得以有限度控制表現水準和表現 時機。 技術上需進一步改良非本生性基因在亞麻子和其他植 物種子内的表現方法。 發明概述As far as the inventors are aware, the performance of non-bensogenic genes in linseed is only contained in PCT Plant Patent Application No. WO 98/1 8948. This case reveals two stearin-mercapto carrier protein thinning enzyme (SAD) genes derived from flax. The relevant SAD priming gene sequences can be used to engineer flax and other plants to express endogenous or foreign genes. However, the method taught by W0 98/1 8948 is limited by the fact that the SAD priming gene has no seed specificity in flax and imparts expression to leaves, stems, flowers, and seeds. The performance of non-native genes can cause undesirable side effects in non-seed tissues. In addition, using SAD to launch genes, there is limited control over performance levels and performance timing. Technically, it is necessary to further improve the expression of non-native genes in linseed and other plant seeds. Summary of invention

The chimeric construct is introduced into the flax plant cells to produce the transformed gene flax plant cells, so that when compared with the non-transformed flax plant cells or the flax plants grown thereby, the flax plant cells of different phenotypes can be detected or grown therefrom. Flax plant. The immediate nucleic acid sequence that is identical to the nucleic acid sequence of the post-construction is not present in the non-transformed flax plant cells or the flax plants grown thereby. In this aspect, the chimeric nucleic acid sequence comprises a sequence comprising a numerator gene linked to a nucleic acid sequence obtained from another plant species, or a nucleic acid sequence derived from flax but which is usually not associated with the priming gene. The chimeric nucleic acid sequences used herein further comprise a sequence comprising a flax-launching gene and a nucleic acid normally associated with a priming gene, but additionally comprising a non-neogenic nucleic acid sequence. For example, if the germination gene is a linseed-specific oleagin-producing gene, the linseedin-initiating gene is a "non-native" sequence, and also contains a sequence of fusion between linseed oil genes naturally associated with the oil-producing gene. And useful coding sequences that are not naturally associated with the priming gene.

Using the non-Agrobacterium techniques, it was possible to obtain transformation and performance within various monocotyledonous and dicotyledonous plant varieties using the above construction. These technologies are particularly useful for the transformation of tough plant varieties in Agrobacterium transformation systems. Other techniques for gene delivery include particle propagation (Samford (1 988), Biotechnology Trend 6: 299-302), electroporation (Fromm et al. (1985), PNAS USA 82: 5824-5828; Riggs and Bates (1986) , PNAS USA 83 : 5 6 02-5 6 0 6 ), PEG intervening DNA uptake (Potrykus et al. (1985), Mol. Gen.
