Cold induced promoter from winter brassica napus

A 1.2 kb fragment of the 5' regulatory region (from bp -1107 to + 100) was fused to the GUS (.beta.-glucuronidase) reporter gene and BN115-promoted GUS expression was observed in green tissues of transgenic Brassica napus plants only after incubation at 2°C. No expression was observed after incubation at 22°C, either in the presence or absence of abscisic acid. Microprojectile bombardment of winter B. napus leaves with a BN115 promoter/GUS construct yielded similar results and was used to analyze a series of deletions from the 5' end of the promoter. Results obtained from transient expression studies showed that the low temperature regulation of BN115 expression involves a possible enhancer region between bp -1107 and -606 and a second positive regulatory region located between bp -302 and -274. Deletion analyses and results from replacement with a truncated CaMV (cauliflower mosaic virus) 35S promoter suggest that the minimal size required for any maintenance of low temperature GUS expression is a -300 by fragment. Within this fragment are two 8 bp elements with the sequence TGGCCGAC, which are identical to those present in the positive regulatory region of the promoter of the homologous Arabidopsis cor15a gene and to a bp core sequence in the low temperature- and dehydration-responsive elements (LTREs and DREs) identified in the promoter regions of several cold-responsive Arabidopsis thaliana genes. Mutation of either one or both of the GGCAC core sequence of the putative LTRE's to AATTC resulted in loss of cold-inducible gene expression, providing for the first time, direct evidence that CCGAC is required for low temperature expression. Furthermore, replacement of an enhancer region (-605 to -1107) of the promoter with a more active enhancer from the 35S constitutive cauliflower mosaic virus (CaMV) promoter resulted in a "hybrid" promoter with increased low temperature induced activity several fold over that of the native promoter.

A thrust plate for a horizontal scroll compressor and a horizontal scroll compressor having the same

A thrust plate for a compressor may include first and second ends and a feed hole. The first end may include a thrust surface. The second end may include a lubricant accumulation feature. The feed hole may extend between the lubricant accumulation feature and the thrust surface to provide communication therebetween. The feed hole may be angled relative to a longitudinal axis of the thrust plate such that lubricant flows through the feed hole from the lubricant accumulation feature to the thrust surface.

Continuous operation method for microwave high-temperature pyrolysis of solid material comprising organic matter

A continuous operation method for the microwave high-temperature pyrolysis of a solid material comprising an organic matter. The method comprises the following continuously performed steps: mixing a solid material containing an organic matter with a liquid organic medium; transferring the obtained mixture to a microwave field; and in the microwave field, continuously contacting the mixture with a strong wave absorption material in an inert atmosphere or in vacuum, wherein the strong wave absorption material continuously generates a high temperature under a microwave such that the solid material containing an organic matter and the liquid organic medium are continuously pyrolyzed to implement a continuous operation. The process is continuous and efficient, can be industrialized, and can obtain a product having components with high added values.
