The invention relates to a cloning and function expression method of an adversity stress AhMYBL6 gene in peanut. The adversity stress AhMYBL6 gene is synthesized by RT-PCR (reverse transcription-polymerase chain reaction) cloning by the steps of preparation and treatment of materials, extraction of RNA (ribonucleic acid) and synthesis of cDNA (complementary deoxyribonucleic acid). The open reading frame of the gene is 861bp, and 287 amino acids are coded totally. The homology of the amino acid sequence of the gene with the MYb family proteins GmMYB4, GmMYB29 and GmMYB29A2 of the soybean is higher than 60%. The fluorescent quantitative PCR verifies the expression patterns of the AhMYBL6 under low temperature, salt stress and drought stress; the result indicates that the expression levels of the AhMYBL6 are obviously enhanced after various stress treatment for 1 hour, and kept at high levels all the time thereafter; and the expression level of the AhMYBL6 in the leaf subjected to low-temperature treatment is maximally enhanced by 20 times. After the gene is transferred into peanut by transgenic means, compared with the control, the transgenic plant has obvious characteristics of cold tolerance, salt tolerance and drought tolerance. The AhMYBL6 gene can obviously enhance the stress tolerance of the peanut.

The invention relates to an environmentally-friendly cross-linked acrylate polymer emulsion and a preparation method thereof. The emulsion consists of six main components through semicontinuous seeded emulsion polymerization, is fine and smooth in appearance and is a blue-fluorescent semitransparent emulsion, a pH value is 7.5+/-0.5, the solid content is 30-50%, the emulsion particle diameter is 50-100 nanometers, and the polymer emulsion has good film-forming property and adhesion after film forming at the 80 DEG C temperature. The environmentally-friendly cross-linked acrylate polymer emulsion has the advantages that due to the fact that an amino acid based anionic surface active agent and an alkyl polyglucoside non-ionic surface active agent both have excellent biodegradability and environmental protection effect and are used for replacing commonly-used alkylphenol polyoxyethylene ether and an alkylbenzene sulfonate surface active agent having poor biodegradability, the environmentally-friendly cross-linked acrylate polymer emulsion is more environmentally-friendly, and the demand for the performances of the emulsion is met.
