Characterization of a novel ERF transcription factor in Artemisia annua and its induction kinetics after hormones and stress treatments
Copyright policy )Characterization of a novel ERF transcription factor in Artemisia annua and its induction kinetics after hormones and stress treatments
The full-length cDNA sequence of AaERF3 was cloned and characterized from Artemisia annua. The bioinformatic analysis and phylogenetic tree analysis implied that the AaERF3 encoded a putative protein of 193 amino acids which formed a closely related subgroup with AtERF1, ERF1 and ORA59 in Arabidopsis. The result of subcellular localization showed that AaERF3 targeted to both of the nuclei and the cytoplasm. The qRT-PCR analysis showed that Green young alabastrums had the highest expression level of AaERF3 in the 5-months-old plants. The qRT-PCR analysis also revealed that ABA, Wound and Cold treatments significantly enhanced the transcript expression of AaERF3. MeJA and Ethylene treatment could also slightly induce the accumulation of AaERF3 transcription.
