WebCHILLING STRESS: HOW IT AFFECTS THE PLANTS AND ITS ALLEVIATION STRATEGIES Abstract Low temperatures have been reported to be having far reaching effects on all plant species. The effects, in turn depend on the low temperature sensitivity of each and every plant species. WebSeedlings of non-transgenic and transgenic plants were treated with chilling stress (12 ℃) for 10 days and kept grown until bud stage under normal growth condition. We found that the emergence of flower buds of NtDUF599-RNAi transgenic plants was approximately 10 days earlier than non-transgenic plants. Furthermore, leaf ...
