Novel materials containing dispersed or aligned biomolecules and/or cells and biomasses, which are preferably chemically modified, can be preferably used as conductors, semiconductors, transistors, resistors or non-conductors and as artificial jewels and gemologic materials, materials for use in computer, aerospace, marine and automobile industries, as well as modified alloys for machines and pipelines, boring and drilling machines and materials, and for pumps and for oil industry, as well as for furniture, for wood paper and cellulose industry, as well as for textile industry.
摘要:
It is intended to provide a pure line plant which is required in constructing a seed propagation variety of orchid. An auxin solution is dropped to unfertilized orchid flowers so as to form seeds based on parthenogenesis. Then these seeds are germinated and haploid plants are selected from orchid plants thus grown. The germinating seeds judges as haploid plants are grown to give pure line plants having doubled chromosomes. Thus, a seed propagation variety of orchid is obtained.
摘要:
The present invention is directed to a DNA construct which includes a modified DNA molecule with a nucleotide sequence which is at least 80%, but less than 100%, homologous to two or more desired trait DNA molecules and which imparts the desired trait to plants transformed with the DNA construct. Each of the desired trait DNA molecules relative to the modified nucleic acid molecule have nucleotide sequence similarity values which differ by no more than 3 percentage points. The DNA construct may further include either a silencer or a plurality of modified DNA molecules. The present invention also relates to host cells, plant cells, transgenic plants, and transgenic plant seeds containing such DNA constructs. The present invention is also directed to a method of preparing a modified nucleic acid molecule suitable to impart multiple traits to a plant, a method of determining whether multiple desired traits can be imparted to plants by a single modified DNA molecule, and a method for imparting traits to plants by transforming the plants with the DNA construct.
摘要:
This invention relates to an isolated nucleic acid fragment encoding a cellulose synthase. The invention also relates to the construction of a chimeric gene encoding all or a portion of the cellulose synthase, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the cellulose synthase in a transformed host cell.
摘要:
‘DR5000’ is a distinctive variety of Dianella revoluta, which is characterized by its combination of bluish leaf color, short height, upright growth habit, very dense shoots, and narrow-to-medium leaf blade.
摘要:
An isolated polynucleotide encoding a fusion protein which comprises a DNA targeting moiety linked to a catalytic domain of a plant DNA methyltransferase 3 (DNMT3) protein is disclosed. Uses thereof are also disclosed.
摘要:
The invention relates to nucleic acids encoding a zingiberene synthase that enables host cells and plants to make zingiberene that is useful in fragrances and for repelling or killing insects. The invention also relates to isolated zingiberene synthases and to methods for making zingiberenes.
