Abstract
An exposure of genetically gibberellic acid-insensitive isolated wheat aleurone tissue/deembryonated seeds to low temperature for 20 hours prior to addition of exogenous gibberellic acid results in a significant increase in sensitivity to gibberellic acid. The results may reflect a low temperature-induced increase in hormone receptor sites and could have important implications for elucidating the nature of the primary site of hormone action.Keywords
