Jones, L. and McQueen-Mason, S. (2004) A role for expansins in dehydration and rehydration of the resurrection plant Craterostigma plantagineum. FEBS Letters, 559 (3). pp. 61-65. ISSN 0014-5793
Abstract
Craterostigma plantagineum is one of the few higher plants capable of surviving desiccation throughout its vegetative tissues. Water loss results in cell shrinkage and a commensurate folding of the cell wall indicating an unusual degree of wall flexibility. We show that wall extensibility undergoes a marked increase during dehydration and rehydration. Similar increases were observed in the activity of expansins in cell walls during these processes suggesting a role for these proteins in increasing wall flexibility. Three α-expansin cDNAs were cloned from dehydrating leaves and transcript levels for one correlated closely with the observed changes in expansin activity during the dehydration and rehydration of leaves.
