| 20120102598 | MIR164 Gene That Controls Plant Root System Development and Fertility and Use Thereof - A rice microRNA, miR164 gene, that controls plant root system development and fertility, is obtained through gene isolation, cloning and function verification. Uses of a nucleic acid fragment comprising miR164, which fragment may confer a transformed plant with the ability to increase root number and to alter fertility, wherein the said nucleic acid fragment is selected from one of the following nucleotide sequences: 1) a DNA sequence as shown in SEQ ID NO: 1; 2) a RNA sequence as shown in SEQ ID NO:2; or 3) the conserved sequence of miR164 having the same function as 1) or 2). The nucleotide sequence containing the precursor of miR164 is ligated with an exogenous promoter and introduced into rice to obtain transgenic rice plants which has large root systems but became infertile. The fertility can be restored by external application of phytohormones. | 04-26-2012 |
| 20120102593 | Use of a Histone Deacetylase Gene OsHDT1 in Enhancing Rice Heterosis - A histone deacetylase gene OsHDT1 which enhances utilization of heterosis in rice is isolated and cloned, said gene consisting of: 1) the DNA sequence of positions 1-894 in SEQ ID NO:1 in the Sequence listing; or 2) a DNA sequence which encodes the same protein as that encoded by the DNA sequence of 1). The histone deacetylase gene OsHDT1 is associated with enhanced utilization of heterosis in rice. When the transgenic plants having no phenotype were crossed with “Zhenshan 97A”, the F1 overexpression hybrid plants have obviously earlier flowering period than F1 wild-type hybrid plants. Moreover, the RNAi inhibition hybrid plants have a decreased seed setting rate compared to the negative control hybrid plants, while the parent RNAi inhibition plants and negative control plants shows no evident difference in the trait of seed setting rate. Western blotting revealed that the gene is capable of deacetylating histone, mainly at H4K16 site. In addition, there exist significant differences in the level of histone modification among “Minghui 63”, “Zhenshan 97” and “Shanyou63”. | 04-26-2012 |
| 20120102591 | Enhancing Salt Tolerance of Plants with Rice OsNHAD Gene - The present invention pertains to the field of rice genetic engineering. Specifically, the present invention relates to a rice OsNHAD gene that enhances tolerance to salt stress, which was obtained through gene isolation, cloning and function verification, and also to use of the gene in genetic improvement of salt tolerance of rice. Said gene is selected from one of the following nucleotide sequences: 1) the nucleotide sequence from positions 60 to 1649 of SEQ NO: 1 in the Sequence Listing; or 2) a nucleotide sequence that encodes the same protein as that encoded by 1). Transgenic rice plants obtained by introducing into rice the nucleotide sequence comprising OsNHAD gene operably ligated with exogenous promoter had enhanced salt tolerance. | 04-26-2012 |
| 20120023621 | Cloning and Application of a Pleiotropic Gene Ghd7 that Controls Grains Yield, Heading Date and Plant Height of Rice - The cloning and application of a pleiotropic gene Ghd7 that controls grains yield, heading date and plant height of rice are provided. The gene has the nucleotide sequence as shown in SEQ ID NO: 1. The sequence of the present gene is 3,917 bp in length, contains two exons and encodes 257 amino acids. The cDNA sequence of the gene is as shown in SEQ ID NO: 1. The present gene encodes a protein having the CCT domain of CO protein and having the amino acid sequence as shown in SEQ ID NO: 1. Rice plants transformed with GHD7 gene are obtained using transgenic technology. The transgenic plants all exhibit markedly increased yield, larger number of spikelets per panicle, delayed heading date and elevated plant height as compared to their respective controls (wild type receptors plants). The trait changes are quite consistent with the phenotypes of the two parent genotypes of GHD7 near isogenic lines of Zhenshan 97. The methods for gene cloning, breeding of near isogenic lines and transgene manipulation are also provided, as well as the application of pleiotropic gene GHD7 in research of rice breeding and plant evolution. | 01-26-2012 |
