The invention discloses a preparation method of anti-aging whitening skin cream based on traditional Chinese medicine exosome extraction, and relates to the technical field of cosmetics. Comprising the following steps: (1) raw material compatibility and pretreatment: taking 1-8 parts by mass of abelmoschus manihot exosome, 1-8 parts by mass of bighead atractylodes rhizome exosome, 1-8 parts by mass of bletilla striata exosome, 1-8 parts by mass of radix angelicae exosome, 1-8 parts by mass of white poria cocos exosome, 1-8 parts by mass of radix paeoniae alba exosome, 1-8 parts by mass of lily exosome, 1-8 parts by mass of silkworm larva exosome, 1-8 parts by mass of white asarum exosome and 1-8 parts by mass of cordyceps sinensis exosome; according to the skin care product disclosed by the invention, the exosome system of twelve traditional Chinese medicinal materials is applied to the field of skin care products for the first time; a complete traditional Chinese medicine exosome extraction, identification and preparation technology system is established; the exosome is used as a natural nano-carrier, so that the skin permeability of active ingredients is remarkably improved; based on the theory of complementing color with color in traditional Chinese medicine, traditional Chinese medicinal materials with white character heads are carefully selected; the exosomes of the medicinal materials have a synergistic effect, so that multi-target skin metabolism regulation is realized.

The invention provides a coNOS gene and a gene engineering method thereof for improving cotton fiber traits. The invention discloses a new target, namely coNOS, which is a nitric oxide (NO) synthase, which can be used for improving fiber traits and / or yield traits of gossypium plants. Functional identification is carried out on the coNOS gene, and cotton plants with significantly increased fiber density, significantly increased fiber quantity and significantly increased yield are obtained through a transgenic technology. The invention also discloses the coNOS for increasing the content of nitric oxide in the fiber and controlling the synthesis of the cell wall of the fiber cell.

The invention discloses a cotton verticillium wilt-resistant gene identification method based on family analysis and application thereof, and 89 LRX family members are identified in four cotton genus by carrying out whole genome identification and analysis on a cotton LRX gene family; through evolutionary analysis, the LRX gene family is divided into four subgroups, the LRX genes in the same subgroup show similar conserved motifs, but some genes show significant differences; through chromosome position analysis and collinearity analysis, the LRX gene family experiences many fragment repetition events and cis-acting element analysis shows that the gene family is likely to participate in various biological and abiotic stress responses. Through an expression mode under the stress of verticillium wilt, a virus-induced gene silencing experiment is carried out by utilizing the GhLRX7, and a gene silencing plant shows more serious disease symptoms, so that the GhLRX7 plays an important role in the aspect of verticillium wilt resistance of cotton.

The invention provides a GSNOR gene and an application of the GSNOR gene in improved cotton plants. The GSNOR gene is subjected to isolation cloning and functional identification, and the expression quantity of the GSNOR gene is regulated and controlled through molecular biology and transgenic technologies, so that the regulation of plant growth and development is realized, and high-quality transgenic cotton with remarkably increased fiber quantity is obtained. The invention discloses functions and application of GSNOR protein and nitric oxide micromolecule signals, and particularly has positive effects in promoting fiber cell differentiation and improving cotton fiber density quality characters. The invention provides a new action target for variety improvement of cotton plants.

This invention discloses primers for the rapid identification of E-genome cotton species in diploid and tetraploid Gossypium and their applications, belonging to the field of molecular biology. Using the primers provided by this invention for the rapid identification of E-genome cotton species in diploid and tetraploid Gossypium, a nucleotide fragment of approximately 350 bp can be specifically amplified in PCR reactions using E-genome cotton species DNA as a template; however, no amplification products are obtained in PCR reactions using genomic DNA from other diploid or tetraploid cotton species as templates, demonstrating high specificity. This method enables rapid and accurate identification of E-genome cotton species, effectively solving the problem of accidental confusion between E-genome cotton species DNA and other cotton species DNA in experimental work, filling the gap in rapid identification technology for E-genome cotton species, and has significant practical value.

1 Abstract The present disclosure relates to the technical field of plant genetic engineering, and in particular, to the use of GhNFXL1 gene in improving the salt tolerance and / or cold tolerance of a Gossypium plant. According to the present disclosure, through various experiments, silencing the GhNFXL1 gene will reduce the salt tolerance and cold tolerance of plants; the overexpression of the GhNFXL1 gene enhances the salt tolerance and cold tolerance of plants. The results show that GhNFXL1 plays a positive regulatory role in the salt tolerance and cold tolerance of cotton.
