【 摘 要 】

Pineapple (Ananas comosus (L.) Merr.) is an important tropical fruit with high economic value. The quality and yield of pineapple will be affected by various environmental conditions. Under adverse conditions, plants can produce a complex reaction mechanism to enhance their resistance. It has been reported that the member of ethylene responsive transcription factors (ERFs) plays a crucial role in plant developmental process and stress response. However, the function of these proteins in pineapple remains limited. In this study, a total of 74 ERF genes (AcoERFs) were identified in pineapple genome, named from AcoERF1 to AcoERF74, and divided into 13 groups based on phylogenetic analysis. We also analyzed gene structure, conserved motif and chromosomal location of AcoERFs, and the AcoERFs within the same group possess similar gene structures and motif compositions. Three genes (AcoERF71, AcoERF73 and AcoERF74) were present on unanchored scaffolds, so they could not be conclusively mapped on chromosome. Synteny and cis-elements analysis of ERF genes provided deep insight into the evolution and function of pineapple ERF genes. Furthermore, we analyzed the expression profiling of AcoERF in different tissues and developmental stages, and 22 AcoERF genes were expressed in all examined tissues, in which five genes (AcoERF13, AcoERF16, AcoERF31, AcoERF42, and AcoERF65) had high expression levels. Additionally, nine AcoERF genes were selected for functional verification by qRT-PCR. These results provide useful information for further investigating the evolution and functions of ERF family in pineapple.
