Genome-wide identification, classification, and expression analysis of the HSF gene family in pineapple (Ananas comosus).

ABSTRACT: Transcription factors (TFs), such as heat shock transcription factors (HSFs), usually play critical regulatory functions in plant development, growth, and response to environmental cues. However, no HSFs have been characterized in pineapple thus far. Here, we identified 22 AcHSF genes from the pineapple genome. Gene structure, motifs, and phylogenetic analysis showed that AcHSF families were distinctly grouped into three subfamilies (12 in Group A, seven in Group B, and four in Group C). The AcHSF promoters contained various cis-elements associated with stress, hormones, and plant development processes, for instance, STRE, WRKY, and ABRE binding sites. The majority of HSFs were expressed in diverse pineapple tissues and developmental stages. The expressio
