Functional role of aquaporins models plant to beech trees: David Israel’s PhD defence

The public PhD defence of David Israel is on Friday 27th Jan 2023 13:15-15:15 EET with opponent Oliver Brendel from INRAE at Nancy, France.

David Israel: The ecophysiology of plasma membrane aquaporins in Arabidopsis thaliana and Fagus sylvatica
Biokeskus 2, auditorio 1041, Viikinkaari 5

This research makes the connection from expression of aquaporins in plant membranes to identify their functional role in plant water use, growth and photosynthesis, under imposed stress and seasonal changes in the environment of both model plants and European beech trees.

David’s research is published in four papers:
