Identification of potential transcriptional regulators of actinorhizal symbioses in Casuarina glauca and Alnus glutinosa.

ABSTRACT:

Background

Trees belonging to the Casuarinaceae and Betulaceae families play an important ecological role and are useful tools in forestry for degraded land rehabilitation and reforestation. These functions are linked to their capacity to establish symbiotic relationships with a nitrogen-fixing soil bacterium of the genus Frankia. However, the molecular mechanisms controlling the establishment of these symbioses are poorly understood. The aim of this work was to identify potential transcription factors involved in the establishment and functioning of actinorhizal symbioses.

Results

We identified 202 putative transcription factors by in silico analysis in 40 families in Casuarina glauca (Casuarinaceae) and 195 in 35 families in Alnus glutinosa (Betulaceae) EST databases. Base
