The invention relates in part to plant HMG2 HMGR genes and in part to the "post-harvest" production method of producing gene product of interest in plant tissues and cultures. The HMG2 promoter elements are responsive to pathogen-infection, pest-infestation, wounding, or elicitor or chemical treatments. The HMG2 elements are also active in specialized tissues of the plant including pollen and mature fruits. HMG2 promoter elements and HMG2-derived promoters can be advantageously used to drive the expression of disease and pest resistance genes, whereby transgenic plants containing such gene constructs would be resistant to the targeted disease and pest. In particular, the HMG2 gene expression system can be utilized in developing nematode resistant plants. The post-harvest production method of the invention utilizes plant tissues and cell cultures of plants or plant cells engineered with a expression construct comprising an inducible promoter, such as the HMG2 promoter, operably linked to a gene of interest. Production of the desired gene product is obtained by harvesting, followed by inducing and processing the harvested tissue or culture. The post-harvest production method may be advantageously used to produce direct or indirect gene products that are labile, volatile, toxic, hazardous, etc.

The invention pertains to the use of (i) one or more C2-C6 alpha-hydroxy acids, salts of these acids, esters of these acids and combinations thereof; and (ii) one or more compounds selected from—the group of amino acid derivatives consisting of γ-glutamyl amino acids, pyroglutamyl amino acids, glutamate-containing or proline-containing dipeptides, oxo-aminoacids, homo-amino acids, N-acetyl amino-acids and glycyl-glycine; -phenolic acid derivatives; -linear C2-C6 or cyclic C6 sugar alcohols; -pyridinic acid derivatives; and -nucleobases and / or nucleotides chosen from uracil, adenine, adenosine 3′-monophosphate (3′-AMP) and adenosine 5′-monophosphate (AMP), as a growth-and production promoting ingredient, in culture media for culturing eukaryotic cells. The invention further pertains to culture media containing these components at levels of at least 0.001 mg / l.

The invention discloses a plastic profile all-steel type cooling water tank which comprises a tank body, a cover plate, inserting plates and water cooling shaping blocks. The inserting plates are vertically arranged in the tank body. Each water cooling shaping block is connected into the corresponding inserting plate in an inserted manner. The lengths of inserting grooves in the two sides of each inserting plate are different. An S-shaped water path is formed by the inserting plates. Equal-length stop blocks are arranged in the inserting grooves of each inserting plate. The stop blocks abut against the edges of the water cooling shaping blocks in the inserting grooves. Shaping holes in the water cooling shaping blocks are in one-to-one correspondence. According to the plastic profile all-steel type cooling water tank, heat expansion and cold contraction caused by the air temperature influence is avoided, and the sealing performance is high; the inner water path is designed to be the S circulation water flow direction, and therefore water flowability is increased; it is guaranteed that a plastic profile can be fast cooled and shaped, and the forming quality of the profile is improved; and meanwhile, the all-steel water tank is integrated, the sealing performance is high, a manufacturing process is simplified, water tank assembly errors are small, and the sealing performance is good. Resources are saved, cost is reduced, and therefore production is improved.

The invention provides a preparation method of a cultigen culture medium by taking unhusked rice as raw material. The preparation method includes the steps of material sorting, soaking, cleaning, mixing, bottling and sterilizing, inoculating and cultivating. The culture medium of edible fungus cultigen, which is prepared by taking the unhusked rice as the raw material, neither gives birth to bugs nor mildew, and has strong ability of resisting sundry fungus. After the culture medium of edible fungus cultigen is inoculated, the hypha buds quickly and grows strong with the rate of survival reaching 100%, and the strain can be preserved for a long period of two months.
