Comparative transcriptomics in three Methylophilaceae species uncover different strategies for environmental adaptation

We carried out whole transcriptome analysis of three species of Methylophilaceae, Methylotenera mobilis, Methylotenera versatilis and Methylovorus glucosotrophus, in order to determine which metabolic pathways are actively transcribed in cultures grown in laboratory on C1 substrates and how metabolism changes under semi-in situ conditions. Comparative analyses of the transcriptomes were used to...

Considerations for the use of transcriptomics in identifying the 'genes that matter' for environmental adaptation.

Transcriptomics has emerged as a powerful approach for exploring physiological responses to the environment. However, like any other experimental approach, transcriptomics has its limitations. Transcriptomics has been criticized as an inappropriate method to identify genes with large impacts on adaptive responses to the environment because: (1) genes with large impacts on fitness are rare; (2) ...

Evaluation of different strategies for domain adaptation in opinion mining

The work presented in this article takes place in the field of opinion mining and aims more particularly at finding the polarity of a text by relying on machine learning methods. In this context, it focuses on studying various strategies for adapting a statistical classifier to a new domain when training data only exist for one or several other domains. This study shows more precisely that a se...

Comparative genomic analysis reveals the evolution and environmental adaptation strategies of vibrios

BACKGROUND Vibrios are among the most diverse and ecologically important marine bacteria, which have evolved many characteristics and lifestyles to occupy various niches. The relationship between genome features and environmental adaptation strategies is an essential part for understanding the ecological functions of vibrios in the marine system. The advent of complete genome sequencing technol...
