Unraveling Auxin Transport Mechanisms: Implications for Plant Development and Environmental Adaptation

Auxin is a pivotal hormone in plants, orchestrating a myriad of developmental processes and enabling environmental adaptability. The discovery of PIN exporters significantly advanced our understanding of auxin's directional transport, which is essential for processes such as embryogenesis and the coordination of growth. Despite these advancements, the precise molecular mechanisms governing auxin transport remain not fully elucidated. Recent studies focusing on Arabidopsis cotyledons and tea plant lateral roots have highlighted the complexity of interactions between auxin and other hormones, thereby underscoring the necessity for further exploration of auxin's molecular transport mechanisms and its integration with environmental signals.This Research Topic aims to elucidate the role of auxin transport in plant development and adaptation. It seeks to understand how auxin's regulation and interaction with various signaling pathways contribute to plant growth and response to environmental changes. The intention is to answer key questions about the regulatory networks of auxin, test hypotheses concerning auxin's integration with other hormonal pathways, and uncover its contributions to the broader environmental response mechanisms in plants.To gather further insights into this multifaceted area of study, we welcome articles addressing, but not limited to, the following themes:• Mechanisms of PIN exporters, AUX1/LAX influx carriers, ABCB transporters, PILS proteins and their roles in plant development• Interaction of auxin transport with other hormonal pathways• Molecular basis of auxin's response to environmental stimuli• Auxin transport and regulation in Arabidopsis and other model plants• Advances in understanding auxin's role in plant growth coordination and developmentWe invite submissions of various article types, including original research, reviews, and methodological papers, to enrich our understanding of auxin's pivotal role in plant biology.
