Genome-wide identification, phylogeny, and expression analysis of GRF transcription factors in pineapple (Ananas comosus).

ABSTRACT:

Background

Pineapple is the only commercially grown fruit crop in the Bromeliaceae family and has significant agricultural, industrial, economic, and ornamental value. GRF (growth-regulating factor) proteins are important transcription factors that have evolved in seed plants (embryophytes). They contain two conserved domains, QLQ (Gln, Leu, Gln) and WRC (Trp, Arg, Cys), and regulate multiple aspects of plant growth and stress response, including floral organ development, leaf growth, and hormone responses. The GRF family has been characterized in a number of plant species, but little is known about this family in pineapple and other bromeliads.

Main discoveries

We identified eight GRF transcription factor genes in pineapple, and phylogenetic analysis placed them into five s
