Transcription profiling by array of Physcomitrella patens Gransden strain at gametophore stages under cold stress

ABSTRACT: Temperature reduction is a common environmental stress for plants. Land plants need to cope with cold stress on the basis of complex transcriptional and metabolic changes. The transcriptional responses and signaling networks that contribute to cold acclimation of seed plants have been analyzed previously. Here, we present the whole-genome transcriptomic cold stress response of the model moss species Physcomitrella patens as the representative of an early diverged lineage of haploid-dominant and poikilohydric land plants On the basis of time-series microarray experiments we characterized transcriptomic changes related to early stress signaling and the initiation of cold-acclimatory mechanisms, and as secondary effects, of dehydration and oxidative stress.

The whole-genome transcriptomic cold stress response of the moss Physcomitrella patens was analyzed and correlated with phenotypic and metabolic changes. Based on time-series microarray experiments and quantitative real-time polymerase chain reaction, we characterized the transcriptomic changes related to early stress signaling and the initiation of cold acclimation. Transcription-associated protein (TAP)-encoding genes of P. patens and Arabidopsis thaliana were classified using generalized line  ...[more]
