Here, five common European tree species were selected (Acer campestre L., Acer pseudoplatanus L., Carpinus betulus L., Corylus avellana L. and Fraxinus excelsior L.) to study their hydraulic thresholds to mortality. Photosynthetic parameters during desiccation and the recovery of leaf gas exchange after rewatering were measured. Stem vulnerability curves and leaf pressure-volume curves were investigated to understand the hydraulic coordination of stem and leaf tissue traits. Stem and root samples from well-watered and severely drought-stressed plants of two species were observed using transmission electron microscopy to visualize mortality of cambial cells. The lethal water potential (.lethal) correlated with stem P99 (i.e., the xylem water potential at 99% loss of hydraulic conductivity, PLC). However, several plants that were stressed beyond the water potential at 100% PLC showed complete recovery during the next spring, which suggests that the.lethal values were underestimated. Moreover, we observed a 1:1 relationship between the xylem water potential at the onset of embolism and stomatal closure, confirming hydraulic coordination between leaf and stem tissues. Finally, ultrastructural changes in the cytoplasm of cambium tissue and mortality of cambial cells are proposed to provide an alternative approach to investigate the point of no return associated with plant death."],["dc.description.sponsorship","China Scholarship Council (CSC)"],["dc.identifier.doi","10.1093/treephys/tpv117"],["dc.identifier.isi","000371184000005"],["dc.identifier.pmid","26614785"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/41473"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Oxford Univ Press"],["dc.relation.issn","1758-4469"],["dc.relation.issn","0829-318X"],["dc.title","Leaf gas exchange performance and the lethal water potential of five European species during drought"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Here, we investigate intervessel pit membrane thickness (T-PM) and embolism resistance (P-50, i.e., the water potential corresponding to 50% loss of hydraulic conductivity) across a broad range of woody angiosperm species. Data on T-PM and double intervessel wall thickness (T-VW) were compiled based on electron and light microscopy. Fresh material that was directly fixated for transmission electron microscopy (TEM) was investigated for 71 species, while non-fresh samples were frozen, stored in alcohol, or air dried prior to TEM preparation for an additional 60 species. T-PM and P50 were based on novel observations and literature. A strong correlation between T-PM and P50 was found for measurements based on freshly fixated material (r = 0.78, P < 0.01, n = 37), and between T-PM and T-VW (r = 0.79, P < 0.01, n = 59), while a slightly weaker relationship occurred between T-VW and P50 (r = 0.40, P < 0.01, n = 34). However, non-fresh samples showed no correlation between T-PM and P50, and between T-PM and T-VW. Intervessel pit membranes in non-fresh samples were c. 28% thinner and more electron dense than fresh samples. Our findings demonstrate that T-PM measured on freshly fixated material provides one of the strongest wood anatomical correlates of drought-induced embolism resistance in angiosperms. Assuming that cellulose microfibrils show an equal spatial density, T-PM is suggested to affect the length and the shape of intervessel pit membrane pores, but not the actual pore size. Moreover, the shrinking effect observed for T-PM after dehydration and frost is associated with an increase in microfibril density and porosity, which may provide a functional explanation for embolism fatigue."],["dc.identifier.doi","10.1163/22941932-20160128"],["dc.identifier.isi","000377342500003"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/41863"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Brill Academic Publishers"],["dc.relation.issn","2294-1932"],["dc.relation.issn","0928-1541"],["dc.title","INTERVESSEL PIT MEMBRANE THICKNESS AS A KEY DETERMINANT OF EMBOLISM RESISTANCE IN ANGIOSPERM XYLEM"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
