Genome-Based Examination of Chlorophyll and Carotenoid Biosynthesis in Chlamydomonas reinhardtii    

2005

Abstract The unicellular green alga Chlamydomonas reinhardtii is a particularly important model organism for the study of photosynthesis since this alga can grow heterotrophically, and mutants in photosynthesis are therefore conditional rather than lethal. The recently developed tools for genomic analyses of this organism have allowed us to identify most of the genes required for chlorophyll and carotenoid biosynthesis and to examine their phylogenetic relationships with homologous genes from vascular plants, other algae, and cyanobacteria. Comparative genome analyses revealed some intriguing features associated with pigment biosynthesis in C. reinhardtii; in some cases, there are additiona…

Traditional fermented sausage ‘Nem chua’ as a source of yeast biocatalysts efficient for the production of the aroma compound γ-decalactone

2013

International audience; The yeast ecosystem of Nem chua, a Vietnamese traditional fermented sausage naturally rich in medium‐chain‐length lipid‐derived flavouring compounds, was investigated to select biocatalysts able to produce the C10‐fatty acid‐derived aroma compound γ‐decalactone. The total number of yeast was about 5 × 104 to 4 × 105 CFU g−1, and eighty four different species were identified from morphological, physiological and 26S rDNA characteristics, with Candida sake and Candida haemulonii being found in all samples. Six strains able to produce γ‐decalactone from castor oil were selected, of which three Yarrowia lipolytica strains were able to produce between 1 and 2 g L−1 in our…

La voix des outsiders ? Internet dans les partis politiques américains

2011

Chapitre 6.; International audience; Les superlatifs abondent quand on évoque les modifications électorales liées à internet aux États-Unis. Dick Morris, un ancien conseiller de Bill Clinton, parle ainsi d’un « cinquième pouvoir », celui des réseaux en ligne. Le fait est que, depuis le milieu des années 2000, les candidats se sont emparés de toutes les possibilités offertes par internet : financement de l’effort de campagne, commentaire...

The effects of mobile banking application user satisfaction and system usage on bank-customer relationships

2016

This study examines mobile banking (m-banking) application usage in Finland by linking it with customer-bank relationship development. Specifically, we examine how usage is related to relationship commitment, overall satisfaction, intention to recommend the bank and future intentions to remain with the bank. A survey was used to collect data from experienced mbanking application users. In total, 273 valid responses were received. The results support the hypotheses and reveal that user satisfaction with m-banking application usage has a strong positive association with usage of m-banking applications. Usage, in turn, was positively related to all examined bank-customer relationship related v…

Intelligence and Music: Lower Intelligent Quotient Is Associated With Higher Use of Music for Experiencing Strong Sensations

2020

Intelligence is a key psychological feature associated to emotion and perception. Listening to music is often linked to emotional experience and sensation seeking (SS), traits that have been shown overall negatively correlated with intelligence. In a sample of 53 musicians and 54 non-musicians, we assessed the use of music for experiencing strong emotions through the Music in Mood Regulation (MMR) and the intelligence quotient (IQ) by using the Wechsler Adult Intelligence Scale III (WAIS-III). We found a negative correlation between the full IQ score and the use of music for SS in both musician and non-musician groups. Furthermore, the use of music for SS was negatively correlated with Ver…

Continuous mobile banking usage and relationship commitment – A multi-country assessment

2015

Although conducting banking transactions via mobile phones, smart phones and tablets has become popular in many countries, major gaps exist in our understanding of those who use this technology, particularly how experienced users perceive mobile banking. Drawing from the literature on mobile banking adoption, continuous usage behavior and post-adoption of technology behavior, the authors shed light on the nature of experienced mobile banking users’ relationship commitment (RC) with their bank and personal finances. The study reveals changes in commitment and shows that mobile banking offers substantial added value to users. Overall, this research will help managers better understand the imp…

Iron in Translation: From the Beginning to the End

2021

Iron is an essential element for all eukaryotes, since it acts as a cofactor for many enzymes involved in basic cellular functions, including translation. While the mammalian iron-regulatory protein/iron-responsive element (IRP/IRE) system arose as one of the first examples of translational regulation in higher eukaryotes, little is known about the contribution of iron itself to the different stages of eukaryotic translation. In the yeast Saccharomyces cerevisiae, iron deficiency provokes a global impairment of translation at the initiation step, which is mediated by the Gcn2-eIF2α pathway, while the post-transcriptional regulator Cth2 specifically represses the translation of a subgroup of…

Reliability of mitochondrial DNA in an acanthocephalan: The problem of pseudogenes

2006

The utility of mitochondrial DNA as a molecular marker for evolutionary studies is well recognized. However, several problems can arise when using mitochondrial DNA, one of which is the presence of nuclear mitochondrial pseudogenes, or Numts. Pseudogenes of cytochrome oxidase I were preferentially amplified from Acanthocephalus lucii (Acanthocephala) using a universal PCR approach. To verify the presence and abundance of pseudogenes, length heterogeneity analysis of the PCR fragments was performed. PCR products obtained with universal primers often contained fragments of different sizes. Cloned sequences from universal PCR products nearly always contained sequence abnormalities such as inde…
