摘要:
A transacting DNA binding factor is disclosed. The ASF 1 protein factor specifically binds to the sequence motif TGACG found upstream of the promoter in many plant genes. Coexpression of this protein factor augments the level of expression of the up-regulated promoter containing the TGACG motif.

Detection of a cellular factor from pea and tobacco which binds to a repeated pentameric motif of TGACG present in the -90 to -60 region of the CaMV 35S promoter is disclosed. Also disclosed is a 21 bp promoter element which is capable of imparting root expression capability to a rbcS-3A promoter, normally a green tissue specific promoter.
摘要:
A novel assay system is disclosed for detecting the presence or amount of selected active proteases in biological samples. The assay system utilizes a chimeric protease detector protein composed of three domains: (1) a repressor domain, (2) a protease cleavage domain specific for the protease to be assayed, and a reporter domain. The reporter domain is not detectable when linked to the repressor domain, but becomes detectable upon release from the repressor domain by protease-mediated cleavage. Thus, the activity of the selected protein can be determined by measuring the amount of detectable reporter in the sample. Methods and test kits for using the novel assay system in a variety of in vitro and in vivo applications are also disclosed.

This present invention is a method for converging a plurality of SQL statements into SQL skeletons to enhance database performance analysis and tuning for identifying the most influential SQL skeletons for databases on an RDBMS platform dependent on different standards. In this present invention, the SQL Normalization technique is combined with the accumulation of statistical information, which includes primarily the frequency, along with the cost and number of rows returned by the SQL skeletons. SQL normalization and collection of statistical data are thus the two principal constituents of SQL Convergence. This simple methodology can then be extended to meet various needs depending on the requirements of the RDBMS and the DBA's tuning priorities.
摘要:
An image processing system and method. The image processing system acquires a first set of scan lines in at first field of image data and a second set of scan lines in a second field of image data; the second set of scan lines are interlaced relative to the first set of scan lines and performs a line by line correlation therebetween to provide an error signal or value. The first and second fields are buffered and coupled to a line-to-line correlator. The error signal is used to adjust either the first or the second set of scan lines to correct for skew or blur in the second field of image data.
摘要:
Provided by this invention are transgenic higher plants and cells thereof which have been transformed with the bacterio-opsin (bO) gene to provide greater resistance to pathogen attack. Also, provided are bO vectors for forming the transgenic plants and cells thereof. Additionally, a method for enhancing the resistance of higher plants and cells thereof by attack by one or more pathogens is provided.
摘要:
The present invention provides plant-derived agents to interfere with the nonstructural NS1 gene from the influenza A virus subtype H1N1. More particularly, the siRNAs that exhibit strong inhibitory activity towards NS1, which effectively suppress replication of the influenza virus in mammalian cells. The invention further provides methods for production of siRNAs for the suppression of a broad range of influenza viral subtypes with sequence homologies.
