Abstract Auxin signaling and its components (Auxin/Indole-3-Acetic Acid (Aux/IAA)) are critical for plant growth and
development. Here, we performed a genome-wide annotation and identified twenty-one Aux/IAA genes in strawberry
(Fragaria vesca). Most FveIAAs were located on chromosomes 1, 2, 4, 5, and 6, while no FveIAAs were found in
chromosomes 3 and 7. Phylogenetic analysis divided these genes into nine subfamilies. Most FveIAAs contained the
DNA-binding and Aux/IAA domains, as well as motifs I–IV. There were 2–6 exons in the FveIAA genes based on the
gene structure analysis. Also, we found that four pairs of FveIAA genes underwent segment More >
