The basic/helix-loop-helix (bHLH) transcription factors and their homologs form a large family in plant and animal genomes. They are known to play important roles in the specification of tissue types in animals. On the other hand, few plant bHLH proteins have been studied functionally. Recent completion of whole genome sequences of model plants Arabidopsis(More)
In higher plants, male reproductive development is a complex biological process that includes cell division and differentiation, cell to cell communication etc., while the mechanism underlying plant male reproductive development remains less understood. GAMYB encodes a gibberellins acid (GA) inducible transcription factor that is required for the early(More)
The major objective of the present study is to change the alanine production of Lactic acid bacteria by expression of Bacillus subtilis (natto) alanine dehydrogenase (AlaDH), the gene that is not present in Lactic acid. B. subtilis AlaDH gene (ald) was cloned into a pGEX6p-1 and expressed in E. coli JM109. Its enzyme activity was 48.3U/mg at 30 degrees C(More)
G-protein-coupled receptors (GPCRs) are found in a wide range of organisms and are central to a cellular signaling network that regulates many basic physiological processes. GPCRs are the focus of a significant amount of current pharmaceutical research because they play a key role in many diseases. In this paper, we predict the functional nonsynonymous(More)
The extraction of urban vegetation information is a focal study point of the city remote sensing. To address the limitations of urban regional scale and the features of extraction of urban vegetation from high resolution satellite image based on object-oriented approach, this paper presented a new approach to use segmentation of high-resolution remote(More)
Bioaminergic receptors are involved in controlling a variety of physiological functions. An approach to predict the functional sites in bioaminergic receptors was described and applied in this study. Given an alignment and receptors with already known subfamily definition, the method identified the global and subfamily-specific functional sites based on the(More)
Method of physical optics is used to simulate backetscattering cross section of dihedral corner and triangular trihedral corner, RCS characteristic of dihedral corner reflectors with a series of parameter changing is analyzed, such as the width, length and intersection angle etc. The reliability of RCS simulation for triangular trihedral corner in this(More)
An efficient method to extract urban road based on the side trees from a high resolution remote sensing image is proposed. First, the high resolution remote sensing image was preprocessed so as to improve the extraction accuracy and reduce the difficulty of later treatment. Second, according to the reflective property of side trees and urban road, it is(More)
In this study, we explored the potential applications of the Ozone Monitoring Instrument (OMI) satellite sensor in air pollution research. The OMI planetary boundary layer sulfur dioxide (SO2_PBL) column density and daily average surface SO2 concentration of Shanghai from 2004 to 2012 were analyzed. After several consecutive years of increase, the surface(More)
