Ultrastructure and Composition of the Nannochloropsis gaditana Cell Wall
Tập 13 Số 11 - Trang 1450-1464 - 2014
ABSTRACT Marine algae of the genus Nannochloropsis are promising producers of
biofuel precursors and nutraceuticals and are also harvested commercially for
aquaculture feed. We have used quick-freeze, deep-etch electron microscopy,
Fourier transform infrared spectroscopy, and carbohydrate analyses to
characterize the architecture of the Nannochloropsis gaditana (strain CCMP 526)
cell wall, whose r...
Metal-Responsive Transcription Factors That Regulate Iron, Zinc, and Copper Homeostasis in Eukaryotic Cells
Tập 3 Số 1 - Trang 1-13 - 2004
Gene Targeting in Aspergillus fumigatus by Homologous Recombination Is Facilitated in a Nonhomologous End- Joining-Deficient Genetic Background
Tập 5 Số 1 - Trang 212-215 - 2006
ABSTRACT The akuA gene encoding the Ku70 component of the nonhomologous
end-joining machinery was deleted in the opportunistic pathogen Aspergillus
fumigatus . No obvious phenotype could be assessed for the corresponding mutant
strain but relative frequencies of homologous recombination were increased as
deduced from targeting the laccase-encoding abr2 gene....
Our Paths Might Cross: the Role of the Fungal Cell Wall Integrity Pathway in Stress Response and Cross Talk with Other Stress Response Pathways
Tập 8 Số 11 - Trang 1616-1625 - 2009
ABSTRACT Fungi occupy diverse environments and are subjected to many extreme
conditions. Among the stressful conditions faced by fungi are pH changes,
osmotic changes, thermal changes, oxide radicals, nutrient deprivation, and
exposure to chemicals. These adversities can be found either in the environment
or in animal and human hosts. The cell wall integrity (CWI) pathway provides a
means to forti...
Heat Stress Activates the Yeast High-Osmolarity Glycerol Mitogen-Activated Protein Kinase Pathway, and Protein Tyrosine Phosphatases Are Essential under Heat Stress
Tập 1 Số 2 - Trang 163-173 - 2002
ABSTRACT The yeast high-osmolarity glycerol (HOG) mitogen-activated protein
kinase (MAPK) pathway has been characterized as being activated solely by
osmotic stress. In this work, we show that the Hog1 MAPK is also activated by
heat stress and that Sho1, previously identified as a membrane-bound osmosensor,
is required for heat stress activation of Hog1. The two-component signaling
protein, Sln1, ...
Cryptococcal Interactions with the Host Immune System
Tập 9 Số 6 - Trang 835-846 - 2010
ABSTRACTOpportunistic pathogens have become of increasing medical importance
over the last decade due to the AIDS pandemic. Not only is cryptococcosis the
fourth-most-common fatal infectious disease in sub-Saharan Africa, but
alsoCryptococcusis an emerging pathogen of immunocompetent individuals. The
interaction betweenCryptococcusand the host's immune system is a major
determinant for the outcome...
Copper-Dependent Iron Assimilation Pathway in the Model Photosynthetic EukaryoteChlamydomonas reinhardtii
Tập 1 Số 5 - Trang 736-757 - 2002
ABSTRACTThe unicellular green algaChlamydomonas reinhardtiiis a valuable model
for studying metal metabolism in a photosynthetic background. A search of
theChlamydomonasexpressed sequence tag database led to the identification of
several components that form a copper-dependent iron assimilation pathway
related to the high-affinity iron uptake pathway defined originally
forSaccharomyces cerevisiae....

Acclimation to Singlet Oxygen Stress in Chlamydomonas reinhardtii
Tập 6 Số 6 - Trang 919-930 - 2007
ABSTRACT In an aerobic environment, responding to oxidative cues is critical for
physiological adaptation (acclimation) to changing environmental conditions. The
unicellular alga Chlamydomonas reinhardtii was tested for the ability to
acclimate to specific forms of oxidative stress. Acclimation was defined as the
ability of a sublethal pretreatment with a reactive oxygen species to activate
defens...
