BACKGROUND: The Aux/IAA protein is integral to the modulation of auxin signaling,
which is essential for plant growth and development. However, systematic analysis
on the Aux/IAA gene family in pineapple (Ananas comosus L.) remains unexplored.
RESULTS: We systematically identified 20 AcAux/IAA genes in pineapple,
classifying them into eight evolutionary groups. Structural analysis revealed
conserved domains (I-IV) and intron-exon patterns, with most genes harboring
hormone/stress-responsive cis-elements. Subcellular localization confirmed
nuclear targeting of all AcIAA-GFP fusion proteins. Tissue-specific expression
profiling identified AcIAA1/6/19 as root-enriched, AcIAA2/8 as floral-specific,
and AcIAA7 as leaf-preferential. During fruit development, AcIAA9/17?19 peaked at
ripening stage, while AcIAA1/3?4/6/11?12/15 declined progressively. Yeast
two-hybrid assays uncovered 68 AcIAA-AcARF interactions, with AcARF6/14 showing
broad binding capacity, while AcIAA1/17/20 exhibited no interactions. These
findings present insights into pineapple Aux/IAA genes, revealing their
structural diversity, spatiotemporal expression dynamics, and interaction
networks with AcARFs, and highlight their potential roles in organ development
and fruit ripening. CONCLUSION: This study establishes a foundation for future
functional analyses aimed at elucidating the molecular mechanisms underlying
auxin signaling, which governs fruit yield and quality in pineapples.
