The invention discloses an application of a SCWBC11 protein in culture of a male sterility line of rice, and provides an application of a substance which is expressed by an OSWBC11 protein coding gene in a silent or inactivated target plant to culture of a male sterile plant. In the application, the amino acid sequence of the OSWBC11 protein is the sequence 2 in the sequence table. The target plant is dicotyledon or monocotyledon and monocotyledon is specifically rice. Experiments verify that by adopting an RNA (Ribonucleic Acid) interference method, OSWBC11 protein expression interference is carried out on wild rice Nipponbare, so that the protein function is lost and rice cannot produce pollen, thereby forming the male sterility line. Therefore, the protein has an important application value to the forming mechanism of pollen of rice and the application of the protein to crossbreeding of rice can be explored.

The present disclosure relates, according to some embodiments, to compositions, organisms, systems, and methods for expressing a gene product in a plant (e.g., a monocot) using a promoter operable in one or more plant tissues and/or cells. In some embodiments, an artificial nucleic acid may comprise an expression control sequence having the sequence selected from the sequence of nucleotides 1-4710 of SEQ ID NO: 1 and the sequence of nucleotides 1137-4710 of SEQ ID NO: 1, wherein the expression control sequence has stem-regulated promoter activity in at least one monocot (e.g., at least two monocots).

The present invention provides methods and compositions for making and using transgenic plants that exhibit increased nitrogen storage capacity compared to wild-type plants. Methods of the invention comprise inducing overexpression of monocot-derived vegetative storage proteins (VSPs) in plants, particularly in monocots. In some embodiments, at least one nucleotide construct comprising a nucleotide sequence encoding the ZmLox6 protein or a biologically active fragment or variant thereof is introduced into a plant. Depending upon the objective, the nucleotide construct may optionally comprise an operably linked coding sequence for a vacuolar sorting signal or plastid transit peptide in order to direct storage of the ZmLox6 protein or biologically active fragment or variant thereof into the vacuolar compartment or plastid compartment, respectively, of the cells in which the VSP is expressed. The invention further provides methods for producing plants with increased nitrogen content and/or increased nutritional value, which is desirable in commercial crops, including those used for forage, silage, and grain production.

The invention discloses a corn drought induced expression gene ZmRD101 promoter and application thereof. The nucleotide sequence of the corn drought induced expression gene ZmRD101 promoter is shown as SEQ ID NO. 1. The promoter of the gene ZmRD101 has the characteristics of induced high expression under drought and low expression in normal growth, and can be used in the field of transgenic breeding. A plant expression vector containing the promoter is constructed and transformed into a genome of a plant such as monocotyledon corn, and a target gene is driven to be specifically and highly expressed under drought and to be low expressed under a normal state. The strain can be used for balancing the contradiction between yield and stress resistance, is used for cultivating a new breeding material, and provides a basis for further stress-resistant breeding of corn.

The invention discloses application of rice spliceosomes GS3.2 in regulation and control of rice grain traits. The invention identifies that a GS3 gene has a plurality of spliceosomes GS3.1-GS3.6, wherein the main spliceosomes are GS3.1 and GS3.2, which respectively account for about 50% and 40% of a total transcript, while GS3.2 reduces the level of GS3.1 form at the RNA level on the one hand, and competitively inhibits signal transduction of GS3.1 at the protein level on the other hand, thereby inhibiting the negative regulation and control effect of GS3.1 and achieving the effect of maintaining the normal size of rice grains. On that basis, the invention inhibits the negative grain size regulation and control function of GS3.1 by expressing GS3.2 in a GS3.1 high-expression strain, thereby achieving the purpose of maintaining the normal size of rice grains. The invention not only solves the problem that the functional differentiation mechanism of the dicotyledon AGG3 and the monocotyledon GS3 is still unclear, but also can be applied to the fields of actual production, breeding and the like of rice as a new rice grain trait regulation and control means.
