Cellulose biosynthesis inhibitors modulate defense transcripts and regulate genes that are implicated in cell wall re-structuring in arabidopsis
(2011-06-01)The cell wall is a multifunctional structure which is implicated in plant growth and development as well as responding to any environmental changes including biotic and abiotic stresses. One of the practical approaches in ... -
Characterization and transcriptomic profiling of Arabidopsis thaliana under cellulose biosynthesis inhibitor treatment
(2018-08-01)Cellulose is one of the most important components of plant cell walls for industry and plant development. Screening mutants resistant to chemicals that conditionally inhibit cellulose synthesis, known as cellulose biosynthesis ... -
Characterization of a carbon source-dependent, phytohormone-responsive, free methionine-(R)-sulfoxide reductase from Komagataeibacter hansenii
(2020-05-01)Komagataeibacter hansenii ATCC 23769 is a gram negative, non-pathogenic, acetic acid bacterium, best known for its ability to produce bacterial cellulose (BC). BC, an extracellular polysaccharide, is an important component ... -
Characterization of a novel cellulose biosynthesis inhibitor, CBI28, in Gluconacetobacter xylinus
(2010-05-01)To study the underlying mechanisms for microbial cellulose biosythesis, a novel compound, CBI28, was used as an inhibitor along with classical genetics and EMS mutagenesis. An EZ-Link Biotin Hydrazide Kit was used to create ... -
Characterization of a secreted escherichia coli 086a:K61 protease that inactivates human coagulation FV
(2011-08-01)Background: Escherichia coli (E.coli) O86a:K61 belongs to the Enteropathogenic E. coli (EPEC) group of pathogens. Acute gastroenteritis affects 2-4 billion people annually and EPEC is associated with 10-40% of hospitalized ... -
Characterization of carbon nanotubes grown by chemical vapour deposition
(2009-08-01)Carbon nanotubes (CNTs), discovered by Ijima in 1991, are one of the allotropes of carbon, and can be described as cylinders of graphene sheet capped by hemifullerenes. CNTs have excellent electrical, mechanical, thermal ... -
Characterization of nanopores with internal cavities for DNA manipulation using Langevin dynamics simulations
(2016-12-01)A novel nanopore geometry is proposed, in which a larger internal cavity is located inside a traditional nanopore. Polymer translocation through this geometry is studied using coarse-grained Langevin dynamics. The most ... -
Characterization of novel genetic alleles of cellulose synthase
(2011-01-01)Cellulose is the most abundant polymer on earth. Despite this, relatively little is known about the proteins and biochemical mechanisms governing cellulose biosynthesis. Only in the past 10 years since the sequencing of ... -
Characterization of OmpT: An outer membrane vesicle protease Escherichia coli that attenuates blood coagulation.
(2013-08-01)Escherichia coli O157:H7 is an emerging food-borne and water-borne pathogen that belongs to Enterohemorrhaghic pathogenic group of bacteria. E. coli O157:H7 colonizes the gastrointestinal tract and is responsible for ... -
Characterization of the ACC-1 Family of cys-loop ligand gated ion channels from the parasitic nematode Haemonchus contortus.
(2020-12-01)Nematode cys-loop ligand-gated ion channels (LGICs) have been extensively studied for decades because of their role in current anthelmintic action and potential as targets for future drugs. Many families of cys loop receptors ... -
Characterization of two component systems of Acinetobacter baumannii.
(2014-10-01)Acinetobacter baumannii is an important opportunistic pathogen of hospital acquired infection, particularly in intensive care units. The emergence and rapid spread of multidrug-resistant A. baumannii strains has become a ... -
Characterization of xylan degradation systems in streptomyces
(2012-07-01)Plant biomass serves as a carbon and energy source for Streptomyces spp. which secrete degradative enzymes capable of breaking down the complex plant biomass into simple saccharides. Hemicellulose is a major component of ... -
Characterizing blood plasma proteins from organ tissue in rainbow trout (Oncorhynchus mykiss) using a non-targeted proteomics approach
(2021-12-01)Protein expression patterns adapt to various cues to meet the needs of an organism. The dynamicity of an organism’s proteome can therefore reveal information about an organism’s health. Proteome databases contain limited ... -
Characterizing immunomodulatory activity of lactic acid bacteria on cell types involved in innate immunity: analysis of the effects of Lactobacillus rhamnosus R0011-derived milk ferments on macrophage polarization and of secretome effects on intestinal epithelial cell cytokine production
