Abstract:
There is provided a carrier for co-culturing a fertilized ovum of an animal by which behavior of the fertilized ovum of an animal can be easily observed in a culture system and by which adhesion and three-dimensional growth of the fertilized ovum become possible at first, as well as there is provided a method of culturing the fertilized ovum of an animal using the co-culturing carrier. There is provided a carrier for co-culturing a fertilized ovum of an animal composed of a cell incorporated type three-dimensionally reconstructed tissue for co-culturing the fertilized ovum of an animal to induce adhesion and three-dimensional growth, of the fertilized ovum as well as there is provided a method of culturing the fertilized ovum of an animal characterized in that the co-culturing carrier is introduced into a culture vessel to culture the fertilized ovum of an animal.
Abstract:
An objective of the present invention is to provide DNAs encoding novel plant proteins having a gibberellin (GA) 2-oxidation activity. Another objective is to modify plant height by utilizing these DNAs for regulating the gibberellin content. PCR was performed using degenerate primers, and novel OsGA2ox2 and OsGA2ox3 genes were obtained. The present inventors discovered that unlike products of other GA2-oxidases such as OsGA2ox1, the product of OsGA2ox3 catalyzes the two-step oxidation of GA20 to GA29 and then of GA29 to GA29-catabolite. In addition, the present inventors also found that the growth of the transgenic rice plants expressing OsGA2ox3 was suppressed as compared to control plants.
Abstract:
Identification of a gene from monocotyledonous plants such as rice, which codes for a transcription factor specific to a stress tolerant gene and provision of a novel environmental stress tolerant plant using the gene. From the rice genome, a gene, which binds to a cis element existing upstream of the gene encoding a stress responsive protein and for a transcription factor to activate the transcription of the gene, is identified. Further, the gene of the transcription factor is used to transform a plant, thereby improving tolerance against environmental stresses such as low temperature, dehydration, and salt stresses.
Abstract:
A roll baler equipped with a hopper 2, and a transporting conveyor 3for carrying bale shaping material discharged from beneath a discharge port 20 defined in the bottom face of the hopper 2 into a material receiving port 40 of the bale-shaping chamber, wherein the transporting conveyor 3 is divided into two parts of: a hopper-side transporting conveyor 3a provided in a space extending from beneath the discharge port 20 to the front position beneath the delivery mechanism 5; and a bale-shaping-chamber side transporting conveyor 3b provided in the space extending from beneath the delivery mechanism 5 to the receiving port 40 of the shaping chamber 4, both these hopper-side transporting conveyor 3a and bale-shaping-chamber-side transporting conveyor 3b being each driven independently one from the other.
Abstract:
A method is provided for producing a male sterile plant by utilizing a plant expression cassette including a nucleic acid which is DNA encoding zinc finger transcription factors (ZPT2-5, ZPT3-1 and ZPT4-1) derived from Petunia and a promoter operatively linked to the nucleic acid. Further, a method is provided for producing a plant having a modified trait by utilizing a plant expression cassette including a promoter derived from the ZPT3-1 and ZPT4-1 genes and a heterologous gene operatively linked to the promoter.
Abstract:
First, monochromatic near infrared light in a wavelength range of 700nm-1100nm from the slit of the near infrared apparatus 1 is applied to a ceramic plate through the optical fiber 7 to measure a transmitted light intensity of the ceramic plate which is a reference material for spectrum measurement. Next, in place of the ceramic plate, a blood collection tube 4 containing a blood sample of which the temperature has been adjusted at a predetermined temperature by a water bath and the like is inserted into the housing portion 5. The transmitted light intensity of the blood sample is thus measured using the same procedure as above. A so-called near infrared absorption spectrum in which absorbance has been plotted against wavelengths is displayed on the screen of the computer 2. Information about object characteristics is extracted from the spectrum data using a calibration equation.
Abstract:
Genomic DNA containing the promoter region of the pMADS3 gene was isolated, ligated to a reporter gene, and then introduced into petunia plants via an Agrobacterium -mediated method. Surprisingly, the resultant plants became double-flowered by conversion of stamens into petaloid structures.
Abstract:
By linkage analysis, the Hd3a gene was successfully isolated. It was discovered that the flowering time of plant could be modified either by introducing the Hd3a gene or by controlling its expression.
