Genome-wide identification and analysis of ERF transcription factors related to abiotic stress responses in Nelumbo nucifera.

ABSTRACT:

Background

Ethylene-responsive factor (ERF) transcription factors belong to the APETALA2/ERF (AP2/ERF) superfamily, and play crucial roles in plant development process and stress responses. However, the function of ERF proteins (especially for their role in response to abiotic stresses) remains scarce in Nelumbo nucifera, which is an important aquatic plant with high ornamental, economic, and ecological values.

Results

A total of 107 ERF genes were identified from the N. nucifera genome, and phylogenetic analysis classified these genes into 11 groups. The NnERF genes in the same group exhibited similar gene structure and conserved motifs, and they were unevenly distributed across the 8 chromosomes, with three pairs of tandem duplications and 21 pairs of segmental duplication
