Abstract:
... Retrotransposons represent a major component of plant genomes; however, large-scale studies on their expression are rare. Massively parallel sequencing offers new analytical possibilities enabling a comprehensive study of retrotransposon RNA transcription. We evaluated the expression of long terminal repeat-retrotransposons in leaves of two sister hybrids Populus × canadensis (P. deltoides × P. ni ...

Abstract:
... The ethylene-responsive factor family is one of the largest families of plant-specific transcription factors that are involved in plant development and stress responses. Previously, we demonstrated that the gene ThERF1, encoding a novel ethylene-responsive factor from Tamarix hispida, negatively modulates abiotic stress tolerance. In the present study, Arabidopsis plants overexpressing ThERF1 had ...
