We report the cloning of a small heat shock protein, Qs HSP17, and an osmotin like protein, Qs_OLP, from cork oak phellem tissue (cork cells). Both genes are expressed in suberizing cells and in other cells subject to endogenous stress associated with free radicals. We provide evidence that smHSPs a...
