Comforting proteins
|
A dehydrin protein from Rhododendron plays a key role in freezing tolerance due to protection from cellular dehydration caused by extracellular freezing. Rajeev Arora and co-workers from Iowa State University have shown that purified RcDhn5-encoded acidic SK2 type dehydrin can protect enzyme activity against dehydration in in viro assays. When the gene was constitutively expressed in Arabidopsis, the transgenic plants exhibited increased freezing tolerance withour prior cold acclimation. With cold acclimation, however, the effect was less pronounced. This is apparently due to dilution of the Rhododendron dehydrin by less effective native dehydrins.

The Society for Free Radical Research Plant Oxygen Group would like to announce a meeting on reactive oxygen and nitrogen species in plants: Plant ROS 2009 in Helsinki, Finland on July 8-10. Registration and abstract submission will start on December 15, 2008. Registration fee will be 400 €. The deadline for abstract submission will be March 1, 2009, after which the registration fee will be 450 €. The number of beds at the conference venue is limited, thus we encourage early registration.
