Auxin-mediated regulation of volatile organic compounds in plantsOA
Auxin is a phytohormone that is critical for plant growth and development.The molecular mechanisms underlying auxin biosynthesis,transport,and signaling are well understood.However,the complex mechanism by which auxin regulates plant volatile biosynthesis has seldom been studied.A growing array of unique auxin-related plant volatiles have recently been discovered.This study comprehensively reviews recent findings on auxin and auxin-related genes and their roles in the formation of plant volatiles.This study highlights the implications of exogenous auxin application,genes involved in auxin signaling transduction,and hormonal crosstalk during volatile compound biosynthesis in plants.Plant hormones facilitate the integration of multiple volatile signals to enable specific and appropriate responses to environmental changes.This will improve our overall understanding of the role of auxins in plant volatile compound metabolic pathways.Recent studies have delineated the considerable advancements in elucidating the intricate methods by which plants employ auxin regulatory pathways to modulate the release of volatile chemicals during development and growth,along with prospective research paths.
