摘要:A blue grain gene of Thinopyrum bessarabicum for regulating synthesis of anthocyanins and the use thereof, belonging to the technical field of plant genetic engineering. The blue grain gene of Thinopyrum bessarabicum is the TbMYB4J gene or TbMYC4J gene, the nucleotide sequence of the TbMYB4J gene being as shown in SEQ ID NO. 1, and the nucleotide sequence of the TbMYC4J gene being as shown in SEQ ID NO. 2 or SEQ ID NO. 3. For the first time, the two blue grain genes TbMYB4J and TbMYC4J for regulating the synthesis of anthocyanins are identified and obtained from the 4J chromosome of Thinopyrum bessarabicum, and influences of different combinations of the TbMYB4J and TbMYC4J genes on the accumulation of anthocyanins are defined by means of transient genetic transformation technology, thereby providing a basis and novel resources for color markers in molecular marker-assisted selection breeding and cross-breeding systems of wheat.

摘要:The synthesis of the naturally occurring kaempferol glycoside SLO1O1-1, as well as analogs thereof, has been accomplished, as has its biochemical evaluation. SLO1O1-1 exhibits selective and potent p90 Rsk inhibitory activity at nanomolar concentrations without inhibiting the function of upstream kinases such as MEK, Raf, or PKC. The synthetic scheme of the invention verified the structural assignment of the natural product and has provided access to material sufficient for detailed biological evaluation.

摘要:A smart cell factory of a high value-added metabolite constructed on the basis of automation technology, which belongs to the technical field of metabolic engineering. According to the present invention, a key enzyme mutant gene with a high efficiency is screened out from an iterative key enzyme gene mutation library by means of weakening the expression of the key enzyme gene of the high value-added metabolite, using the automation technology, and in combination with a mutation-screening-mutation closed-loop protein evolution method. Further provided are a method for constructing the smart cell factory of the high value-added metabolite and the use thereof. According to the present invention, the problem that there is currently no high-throughput molecular probe for the high value-added metabolite or the molecular probe screening thereof is unstable can be effectively solved, and labor costs are reduced, the protein evolution time is shortened, the inhibitory effects of an intermediate product and a final product are reduced, the core metabolic flux is enhanced, and the efficient synthesis of the high value-added compound is achieved.

标题 :Synthesis of nano-sized zeolites
发明人：RIMER JEFFREY D; PARMAR DEEPENDRA; MALLETTE ADAM
权利人:UNIV HOUSTON SYSTEM
摘要:Nano-sized zeolites may be prepared using germanium oxide (GeO 2 ) as a component of the overall synthesis composition. This is accomplished by the addition of GeO 2 as an inexpensive reagent for the synthesis gel. Most of the Ge is retained in the synthesis mixture and the small amount incorporated in the zeolite solid (Si/Ge>100) does not have an appreciable impact on zeolite acidity or other physicochemical properties. The methods disclosed herein circumvent challenges to prepare nano-sized zeolites having dimensions less than 100 nm.
