The present invention relates to non-elicited dedifferentiated plant cells of a plant of the species Lavandula angustifolia, or extracts thereof, and also to the cosmetic composition comprising same, to the uses thereof and to cosmetic treatment processes comprising the application of said composition to the skin for improving and/or reinforcing the barrier function, and also for improving the moisturization of the skin.

The present invention discloses the active substances for preventing hearing deterioration, its preparation method, the pharmaceutical composition containing the active substances, and the preparation method of the pharmaceutical composition. The preparation method of the active substances is performed by plate cultivation, flask cultivation and fermentation tank cultivation, to obtain the active substances of Hericium erinaceus mycelia in powder form. The powder of H. erinaceus mycelia is proved to have the effect of preventing hearing deterioration.

The present invention relates to the use of trehalose, and/or a derivative thereof, as a supplement to a culture medium for culturing hybrid plant embryos in in vitro embryo rescue. The addition of trehalose, and/or a derivative thereof, to the culture medium significantly increased the survival rate of the hybrid plant embryos.

Compositions and methods useful for plant transformation without employing selection and without requiring tissue culture through a callus stage are provided. Transformed monocot plants can be obtained with the compositions and methods.

The invention points to a process of production of anthocyanins from Aristotelia chilensis callus cultures, which is divided into 2 essential steps: the first is the obtaining of biomass in an A. chilensis callus culture, the second step consists of eliciting the production of anthocyanins in the culture, to obtain the desired product. In this way, callus cultivation is presented as a new alternative to provide a nutritional additive rich in anthocyanins appropriate for the food industry, or any other application that requires anthocyanins that does not depend on seasonality or environmental factors.

A method for culturing ginseng cell with high content of ginsenoside, including inducing ginseng cell line: after disinfected and sliced, ultrasonically treating old mountain ginseng, and culturing the old mountain ginseng in a culture medium; screening the ginseng cell line: choosing a variety of culture mediums and using hormones for cell separation and culture, selecting cell lines with better growth morphology and faster growth, and performing solid subculture and liquid suspension culture; optimizing conversion conditions: using acids to treat the chosen cell lines, and controlling the treatment temperature and treatment time, detecting ginsenosides Rg3 and Rh2 in the dried products, determining an optimal treatment condition according to the highest total amount; large-scale industrial production: according to the optimal treatment condition, performing the liquid suspension culture of the selected cell lines and scaling up the scale of culture to obtain large-scale industrial production of ginseng cell products.

The invention provides a callus induction medium for blueberry tissue culture, it takes WPM medium as basic medium, comprises: 0.5-5.0 mg/L CPPU and 0.1-0.4 mg/L 2-ip. The present invention also provides a callus culture method of blueberry, the step thereof comprises: inoculating the blueberry explant into the above callus induction medium to conduct induction culture, to form blueberry callus. The present invention also discloses the medium combination and culture method to culture the above blueberry callus to blueberry tissue culture plant. For the above medium and culture method, the differentiation effect is good, efficiency is high, and can conduct continuous differentiation, and the effect to multiple varieties are all better.

The current invention reports the use of meta-tyrosine for increasing the specific productivity of a eukaryotic cell that produces/expresses a polypeptide. In the current method it is not necessary to perform a temperature-, osmolality- or pH shift or to add drugs like valproic acid or sodium butyrate to modulate the specific productivity of the cultivated cells. The method does not affect cell viability or product titer.

The present invention relates to a method for plant genome modification of at least one plant cell being in the developmental stage of a plant immature inflorescence meristem (IIM) cell, wherein the modification of the specific cell type is achieved by providing a genome modification or editing system, optionally together with at least one regeneration booster, preferably wherein the effector molecules are introduced by means of particle bombardment. To this end, new artificial and precisely controllable booster genes and proteins are provided. Further, the modified plant cells are regenerated in a direct or an indirect way. Finally, methods, tools, constructs and strategies are provided to effectively modify at least one genomic target site in a plant cell, to obtain said modified cell and to regenerate a, plant tissue, organ, plant or seed from such modified cell.

The present invention relates to excision of explant material comprising meristematic tissue from seeds, and storage of such material prior to subsequent use in plant tissue culture and genetic transformation. Methods for tissue preparation, storage, and transformation are disclosed, as is transformable meristem tissue produced by such methods, and apparati for tissue preparation.
