This promoter can start special expression of external source gene in plant endosperm, which is fit for any plant with endosperm such as monocotyledon or dicotyledon.

The present invention discloses a preparation method of slowly-digestible starch-based recombinant rice with a low glycemic index, and belongs to the technical field of food processing. After a high-temperature fluidization technology is used to conduct a non-crystallizing treatment of a solid-phase broken rice raw material in a short time, materials are subjected to a one-step reactive extrusiontechnology, enzyme-adding enzymatic hydrolysis and an esterification treatment are combined, and the recombinant rice with high slowly-digestible starch content and low glycemic index is obtained. Therecombinant rice prepared by the one-step shaping extrusion technology is suitable for consumption of patients with type II diabetes. At the same time, the preparation method increases added value ofagricultural and sideline products, reduces production cost, and improves production efficiency.

The invention discloses a making method of superparamagnetism starch, which comprises the following steps: allocating starch milk through starch and deionized water; adjusting pH value; adding soluble ferrous salt solution to adsorb once; filtering in the vacuum or separating centrifugally; removing water to obtain sediment; adding hydrogen peroxide solution to oxidize once; dehydrating; washing; obtaining starch product with water; repeating these steps to obtain magnified starch product with water; drying; obtaining the product.

The invention provides a method for efficiently preparing a starch-lipid complex. The method comprises the steps: adopting corn starch and fatty acid as raw materials and beta-lactoglobulin as an emulsifier, mixing the three at a mass ratio of 20:1:2, and performing a complexation reaction in a fast viscosity analyzer. When the method is compared with a traditional system without addition of beta-lactoglobulin, the yield of the starch-lipid complex is improved significantly, and the increase rate of the complex content in different fatty acid systems is different and at 28-283%. The starch-lipid complex can be used as an additive for hypoglycemic food, targeted drug controlled release carriers and improvement of intestinal flora and human health, can also be added as fat mimics to food, and has potential special function properties, a high nutritional value, low production cost, easy and continuous production, no pollution to the environment, broad market potential and highly social and economic benefits.

The invention discloses a plant endosperm specific expression promoter and a use thereof. A nucleotide sequence of the promoter is one of the following nucleotide sequences of 1) a DNA sequence limited by sequence 1 shown in a sequence list in the patent specification, 2) a DNA sequence which is above 70% homologous to the DNA sequence limited by the sequence 1 shown in the sequence list and has functions the same as that of the DNA sequence limited by the sequence 1 shown in the sequence list, and 3) a nucleotide sequence which can hybridize with the DNA sequence limited by the sequence 1 shown in the sequence list under highly stringent conditions. The promoter can promote specific expression of a foreign gene in plant endosperm, thus is suitable for any plant of which a seed has endosperm. In other words, the promoter is suitable for monocotyledons or endosperm type dicotyledons.

The invention discloses a shoe, comprising a sole and a vamp which are mutually fixed, wherein a projecting device is arranged in the sole and comprises a power supply assembly, a light source assembly, a control circuit board and a switch assembly which are arranged on the sole. A projection function is added on the basis of flashing, so that cartoon figures popular with children and even pictures of children and all pictures to be projected can be displayed on the ground, walls and other places through a projection mode; furthermore, by setting projection contents, children can know some scientific knowledge in wearing and playing processes; by observing projection phenomena, children can know optical knowledge so as to guide children to sense science and culture scientific interests; of course, adult shoes can be made according to needs. The shoe provided by the invention is novel in design, has higher additional values of science and technology, and can effectively solve the technical problems of single form, common decorative effect, low additional values of science and technology and the like of common flashing shoes.
