摘要： The invention provides the discovery that SCD2 (Susceptible to Coronatine-Deficient Pst DC3118-2) protein converts aldehydes to alkanes, thereby changing the composition and/or amount of synthesized waxes. The invention additionally provides homologs, orthologs and paralogs of SCD2 protein, and nucleotide sequences encoding these proteins. Also provided are expression vectors, transgenic cells, transgenic plants, transgenic seeds, methods for altering alkane production in cells, methods for identifying the function of a nucleotide sequence in the synthesis of plant surface wax, and methods for identifying plant tissue that has an altered surface wax composition. The invention's compositions and methods are useful for altering the amount and/or composition of wax produced by cells, including plants and seeds, that have been transformed with the invention's sequences.

摘要： A process of producing a kaolin product for paper coating includes mining kaolin ores by hydromechanization and then producing kaolin slurry; classifying by centrifugal sedimentation; chemical bleaching; eliminating iron ions by circular rinsing; removing water by pressure filtration; producing slurry by dispersing filter cakes, in which complex dispersants, pH adjustor and intercalator are added; delaminating; classifying by vibrating sieve; and spray drying: spray driers are restructured by adding insulating layers on packing auger, elevator scoop and bunker at first; the kaolin slurry J which has passed through vibrating sieves is dried in high speed centrifugal spray drying tower and the moisture of kaolin powder is controlled in 3 wt. %-5 wt. %, and the kaolin product for paper coating is obtained. The process characterizes in stable properties, high efficiency, and high viscosity content and fine particle size of the kaolin products produced.
