Abstract

Aquaporins are essential for embolism repair in grapevine: i) root vessel embolization in different genotypes was inversely related to aquaporin-mediated water transport, suggesting a role of aquaporins in embolism recovery during stress; ii) no activation of aquaporin-mediated water transport is observed upon water stress; iii) at rehydration, recovery of conductivity is impaired in the presence of HgCl2 in roots and in shoots; iv) aquaporin-mediated water transport can either facilitate rehydration of the vessel-surrounding tissues or directly facilitate entry of water in the embolized vessels.
