A method for creating a seawater desalination reverse osmosis membrane that excels in both water flux and boron removal. The method utilizes the abundant and reactive amino groups of carbon nitride in an interfacial polymerization reaction to enhance the membrane's structure. The unique pore and interlayer structure of carbon nitride is employed to modify the membrane's hydrophilicity, roughness, and interlayer structure, thereby boosting its water flux and boron removal capabilities. Additionally, the carbon nitride solution demonstrates exceptional dispersion properties. Its hydrophilic amino groups react with the organic phase monomer trimesoyl chloride during polymerization, ensuring an even distribution in the polyamide layer without any agglomeration. The evenly dispersed m-phenylenediamine and carbon nitride solution, along with sodium hydroxide in the aqueous phase, quicken the acylation reaction rate. This not only ensures more uniform participation of carbon nitride in the reaction but also further enhances the membrane's water flux and boron removal efficiency.

The present application provides an SNP molecular marker affecting duck fatty acid composition-related gene ELOVL3, and the use thereof in breeding duck meat, identifying meat quality, etc., wherein the SNP molecular marker of the present application is located at -619 bp upstream of the ELOVL3 gene, and the genotype is AA, GG or GA. According to the present invention combined with a GWAS analysis and cell test, SNP located upstream of the ELOVL3 gene that affects the expression activity thereof is identified, and further detection determines that an AA-type individual has a higher polyunsaturated fatty acid carbon chain elongation ability than a GG-type individual, while a dominant genotype that is favorable for improving the fatty acid content of duck meat for seed retention can be selected.

GENE ZmPLD3 FOR INDUCING MAIZE MATERNAL HAPLOID PRODUCTION AND ITS APPLICATION THEREOF
A gene ZmPLD3 for inducing maize maternal haploid production and its application thereof. Transgenic homozygous mutant plants or their progeny can be obtained by knocking out the ZmPLD3 gene in maize, and maize maternal haploids can be produced by hybridizing them as paternal materials with other maize materials. A series of allelic mutations of the gene having maternal haploid induction function through hybridization were obtained. The experiments showed that the mutation of maize phospholipase PLD3 could lead to the production of maize maternal haploid, which provides new thoughts for revealing the biological role of phospholipase in maize maternal haploid induction process. At the same time, the mutant individuals have the maternal haploid induction ability in maize, which is of great significance for breeding new types of haploid induction lines with high haploid induction rate and improving the efficiency of maize haploid breeding.
A method for inhibiting microbial clogging of drip irrigation emitters, belonging to the technical field of water-saving irrigation. The method includes the following steps: (1) Use developmental molecular ecological network analysis to determine the key bacteria causing the clogging of drip irrigation emitters, and then carry out screening of antagonistic bacteria to inhibit the clogging of drip irrigation emitters; (2) Ferment the selected antagonistic bacteria in a medium containing biogas slurry, to generate bacterial antagonist; (3) Apply the bacterial antagonist to drip irrigation system. The method uses the molecular ecological network analysis method to obtain key bacteria that cause the growth of biofilm in drip irrigation emitters, and then combines the principle of microbial antagonism to screen out the antagonistic bacteria that can antagonize the growth of biofilm, so as to inhibit the growth of biofilm in irrigation emitters.
