The ERF transcription factor family in cassava: genome-wide characterization and expression analyses against drought stress.

ABSTRACT: Cassava (Manihot esculenta) shows strong tolerance to drought stress; however, the mechanisms underlying this tolerance are poorly understood. Ethylene response factor (ERF) family genes play a crucial role in plants responding to abiotic stress. Currently, less information is known regarding the ERF family in cassava. Herein, 147 ERF genes were characterized from cassava based on the complete genome data, which was further supported by phylogenetic relationship, gene structure, and conserved motif analyses. Transcriptome analysis suggested that most of the MeERF genes have similar expression profiles between W14 and Arg7 during organ development. Comparative expression profiles revealed that the function of MeERFs in drought tolerance may be differentiated in roots and leaves of different
