This invention relates to compositions and methods facilitating availability, uptake and translocation of active ingredients in plants. More specifically, this invention relates to the surprising discovery that the application to the roots, such as administration to the soil surrounding plants, of two or more osmolytes in combination with an active ingredient, either simultaneously or within a short time of each other, results in an induction of translocation of active ingredient from the roots systemically into the plant.

The invention relates to an electronic method of publishing in a novel format named “ScreenXbook”. The method comprises electronic publishing of printed material in a manner (format) that efficiently displays (“screens”) this material on a screen, for facilitated human reading.

The invention discloses a feed additive for preventing lactation-period-calf diarrhea and an application method thereof. According to the feed additive, natural astaxanthin, sodium humate, beta-hydroxyl-beta-methylbutyric acid, glutamine, xylooligosaccharide and a Chinese herbal medicine additive (agrimonia pilosa ledeb, honeysuckle, Chinese pulsatilla roots, hawthorns, pomegranate bark, talc andlicorice roots) are compounded, the balance of gastrointestinal flora of lactation-period calves is conditioned, development of gastrointestinal mucosa is promoted, the damage and influence of pathogens and unfavorable factors on the calves are reduced, digestion and absorption of nutritional ingredients are increased, the body immunity is improved, the suffered oxidation stress and oxidative damage are relieved, the anti-stress ability is improved, and therefore the aims that occurrence of lactation-period-calf diarrhea is avoided, absorption of feed nutrients is promoted, and the health level and production performance of the calves are improved are achieved.

Sedoheptulose 1,7-bisphosphatase (SBPase) is an enzyme catalyzing the reaction converting sedoheptulose 1,7-bisphosphate into sedoheptulose 7-phosphate. This enzyme is located in the chloroplast in leaves and stems. Overexpression of SBPase in transgenic plants is provided to improve plant yield by increasing leaf starch biosynthetic ability in particular and sucrose production in general. Deregulated variants of the enzymes are also provided.

The invention belongs to the field of nano material biological effect research, and discloses a magnesium-nitrogen-doped carbon dot, a preparation method thereof and application of the magnesium-nitrogen-doped carbon dot in improvement of plant photosynthesis. The preparation method comprises the following steps: dissolving citric acid, ethanolamine and magnesium hydroxide in ultrapure water, carrying out ultrasonic treatment, pouring the treated system into a reaction kettle, and conducting reacting at 200 DEG C for 6 hours; after the reaction is finished, conducting cooling to room temperature, filtering a product by using a filter head with the pore diameter of 0.22 [mu]m, and then conducting dialyzing for 12 hours; and conducting freeze-drying to obtain the magnesium-nitrogen doped carbon dots. After the carbon dots are compounded with chloroplast, the excitation energy can be absorbed by the chloroplast for photosynthesis, so that the photosynthetic activity is improved. After the carbon dots are applied to rice plants through foliage spraying, Mg,N-CDs can be uniformly distributed in leaf cells, expression of related enzyme genes is regulated and controlled, synthesis and metabolism of chlorophyll in leaves are promoted, the activity of chlorophyll molecules is kept at a high level, and therefore the photosynthetic activity of the leaves is improved. Finally, the plant growth is obviously improved.

The invention relates to biologically active food supplements and is intended for preventive action against the states associated with osteoporosis. The technical effect consists in providing a biologically active food supplement which sustains a normal testosterone level in the body, ensures an efficient assimilation of calcium by the body and retention of calcium in the bony tissue for a prolonged time enabling thereby the prevention of osteoporosis.

The invention discloses a chemical treatment preparation for improving the yield of wheat and a chemical treatment method. The chemical treatment preparation comprises gamma-aminobutyric acid, vitaminB6 and a potassium phosphate buffer solution with the pH of 6.5-6.7, wherein 5-10 g of gamma-aminobutyric acid and 2-5 g of vitamin B6 are added into each L of the potassium phosphate buffer solution. The chemical treatment preparation is wholly and uniformly sprayed onto wheat canopy 5-9 days after flowering of wheat every 2-3 days for two times. Gamma-aminobutyric acid is utilized to improve the leaf chlorophyll content and the photosynthetic efficiency, so that the thousand seed weight principle of wheat grains is improved; vitamin B6 is utilized to achieve physiological actions of regulating C and N metabolism, maintaining the stability of a membrane system under adversity and removing active oxygen; and potassium phosphate is utilized to achieve the functions of regulating the pH value and serving as a nutritional element. The chemical treatment preparation is simple to prepare and feasible and reliable in method, and therefore, is an environment-friendly chemical treatment preparation.

The invention discloses a biological agent capable of lowering ammonia nitrogen in an intensive culture pond as well as a preparation method and a using method of the biological agent, belonging to the field of biological agents. The biological agent is prepared from the following raw materials in parts by weight: 5-15 parts of a fungicide, 30-40 parts of a long-acting carbon source and 30-40 parts of a quick-acting carbon source. The biological agent disclosed by the invention has the beneficial effect that the problem in the existing aquaculture that ammonia nitrogen is relatively high and cannot be lowered by virtue of an effective biological method is solved. After being used for a long time, the biological agent disclosed by the invention can be used for acclimating and directionally culturing heterotrophic microbes in water to achieve effects of stabilizing a breeding ecological system, lowering ammonia nitrogen, stabilizing water quality and improving the self-cleaning capacity of the water.

The invention discloses a drought region chili planting soil improvement agent and a preparation method thereof. The drought region chili planting soil improvement agent comprises the following raw material components: bentonite, kaolin, perlite, soybean cakes, turf, animal manure, straws and a nanometer titanium dioxide modified resin additive. The preparation method comprises the following steps: 1) mixing the bentonite and the kaolin, crushing the mixture, adding the perlite, and mixing and stirring to prepare a mixed matrix A; 2) mixing the soybean cake, the turf, the animal manure and thestraws, performing sealing fermentation, drying the fermentation material after fermentation, and crushing into particles for future use; 3) mixing and stirring the mixed matrix A in the step 1) andthe fermentation material particles in the step 2), slowly adding the nanometer titanium dioxide modified resin additive in the stirring process and preparing the drought region chili planting soil improvement agent after stirring uniformly. The soil improvement agent prepared according to the method can effectively improve the current situation of drought and barren soil, reduce water loss and improve the soil fertility, and is favorable for the growth of chili.

A process for biologically synthesizing the extracellular cholesterol oxidase from Brevibacterium is disclosed. The high-output bacterium DGCDC-82 is fermented in optimized condition to obtain said enzyme up to 700-1000 U/L. After purified, its specific enzyme activity can reach 30 U/mg. Said enzyme contains coenzyme FAD and cysteine in the active center of enzyme. In the dual-phase (water phase and organic phase) system, said enzyme can be used to uniquely oxidize the cholesterol to becone cholest-4-ene-3-ketone with 92% of transfer rate, which can be used to reduce cholesterol, blood fat and low-density lipoprotein, so having wide application range.
