In seed plants, drought causes declines in plant water status which increases leaf endogenous abscisic acid (ABA) levels required for stomatal closure. There are multiple possible points of increased belowground resistance in the soil–plant atmospheric continuum that could decrease leaf water potential enough to trigger ABA production and the subsequent decreases in transpiration.We investigate the dynamic patterns of leaf ABA levels, plant hydraulic conductance and the point of failure in the soil–plant conductance in the highly embolism-resistant species Callitris tuberculata using continuous dendrometer measurements of leaf water potential during drought.We show that decreases in transpiration and ABA biosynthesis begin before any permanent decreases in predawn water potential, collapse in soil–plant hydraulic pathway and xylem embolism spread.We find that a dynamic but recoverable increases in hydraulic resistance in the soil in close proximity to the roots is the most likely driver of declines in midday leaf water potential needed for ABA biosynthesis and the onset of decreases in transpiration.This work was funded by a National Science Foundation grant (IOS-2140119) and USDA National Institute of Food and Agriculture (Hatch project 1014908) to SAMM and Spanish Ministry of Science award (PRE2019-090354) to JP.Peer reviewedJohn Wiley & SonsNational Science Foundation (US)National Institute of Food and Agriculture (US)Ministerio de Ciencia e Innovación (España)Manandhar, Anju [0000-0001-5687-2957]Rimer, Ian [0000-0002-7727-972X]Soares Pereira,Talitha [0000-0001-9929-718X]Pichaco, Javier [0000-0002-5202-9994]Rockwell, Fulton [0000-0002-2527-6033]McAdam, Scott [0000-0002-9625-6750]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202420242024info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/366383reponame:DIGITAL.CSIC.
