A novel Gossypium barbadense ERF transcription factor, GbERFb, regulation host response and resistance to Verticillium dahliae in tobacco.

ABSTRACT: Ethylene-responsive factors (ERFs) are commonly considered to play an important role in pathogen defense responses. However, only few of ERF members have been characterized in Sea island cotton (Gossypium barbadense). Here, we reported a novel AP2/ERF transcription factors gene, named GbERFb which was cloned and identified from Sea island cotton by RACE. The expression of GbERFb was significantly induced by treatments with ethylene, Methyl jasmonate, salicylic acid, wounding, H₂O₂ and Verticillium dahliae (V. dahliae) infection. Bioinformatics analysis showed that GbERFb protein containing a conserved ERF DNA binding domain and a nuclear localization signal sequence, belonged to IXb subgroup of the ERF family.
