Methods and compositions for stress tolerance in plants

摘要

We characterise a plant transcription factor and disclose its use in modifying plant responses to stress conditions, including freezing, drought, salinity and pathogen invasion. Microarray analyses were performed indicating that such tolerance occurs via the increase of antifreeze proteins localized in the cellular apoplast which inhibit the growth of large extracellular ice crystals. We also disclose the use of such proteins.
