Abstract
Bordered pit membranes play a crucial role in drought-induced embolism formation via the process of air-seeding, which remains one of most important challenges in our understanding of water transport under negative pressure.
Recent progress in the structural and chemical composition of pit membranes provides a much desired, novel view on the mechanisms behind air-seeding.
In this brief review, we discuss the functional importance of pit membrane thickness in relation to embolism resistance, the potential occurrence of shrinkage and increased porosity of pit membranes during dehydration, and the role of surface active compounds in air-seeding.
