The herbicide-tolerant rice cultivar designated “PVL01” and its hybrids and derivatives are disclosed. The present invention provides a method for producing rice, wherein said rice is tolerant to a quizalofop herbicide or tolerant to a tepraloxdyim herbicide; wherein said rice belongs to any of (a) variety “PVL01” or (b) a hybrid, derivative, or progeny of “PVL01”. Further provided are methods for producing a hybrid or a new variety by crossing the rice variety “PVL01” with another rice line, one or more times. In another embodiment, this invention allows for single-gene converted plants of “PVL01”. In another embodiment, this invention provides regenerable cells for use in tissue culture of rice plant “PVL01”.

The present invention relates to a rice plant material capable of reducing methane emission by reducing organic acid, such as fumarate, secretion from the roots of the rice plant. The reduction in organic acid, such as fumarate, secretion reduces the amount of methanogens associated with the roots of the rice plant and thereby reduces the emission of methane from such methanogens.

A method of enhancing grain yield of a Gramineae plant is provided. The method comprises: (a) crossing a recipient plant with a donor plant comprising a sequence variation in a TPR allele, said sequence variation imparting enhanced grain yield; and (b) selecting a progeny plant of said crossing comprising said sequence variation by identifying said variation, said progeny plant being characterized by an improved grain yield relative to said recipient plant. Also provided are plants and processed products resultant of the method.

The present disclosure provides a heat-stress related gene ZmHsf11 and an application of the gene in regulating heat resistance of plants. The present disclosure belongs to the field of biotechnology. The present disclosure reports for the first time a heat resistance negative regulation related gene ZmHsf11 and its protein. In the present invention, it is found that the expression of ZmHsf11 gene can be induced by adverse stresses such as high temperatures. By overexpressing the gene in rice and identifying functions of the gene, it is found that a survival rate of the overexpressed rice plant under the heat treatment is significantly reduced after overexpression. By identifying functions of the ZmHsf11 mutant plant obtained in the present invention, the heat resistance of the mutant plant is significantly increased after the heat treatment.

Disclosed are rice environmental conditional-lethal mutant gene osesl1, an encoding protein and use thereof The gene osesl1 has a nucleotide sequence shown as SEQ ID NO: 1 in the Sequence Listing. The encoding protein thereof has an amino acid sequence shown as SEQ ID NO: 2. After heading of osesl1 mutant rice, seed embryo lethal phenotype appears at 12 days after pollination, exhibiting darkening at the junction between embryo and endosperm. When an average temperature is below 22° C., a seed embryo is normal; when the average temperature is above 28° C., the seed embryo is lethal; when the temperature is between 22° C. and 28° C., the seed embryo is lethal under long daylight conditions (>13 h) and normal under short daylight conditions (<13 h). Use of the gene osesl1 in controlling seed embryo development of rice is further provided.
