Abstract: This present disclosure relates to methods and composition matters for improving a plant's stress tolerance and a speedy recovery to growth from a stress comprising the process of constitutive expression of a constitutive triple response 1 (CTR1) protein kinase in the nucleus of the cell of said plant. To survive environmental extremes, plants need to rapidly acclimate to stress in order to recover once stress is removed. Here, we uncover a mechanism governing a fast growth recovery of plants following ethylene-induced growth cessation. Ethylene triggers translocation of the CONSTITUTIVE TRIPLE RESPONSE1 (CTR1) protein kinase, a negative regulator of ethylene signaling, from the endoplasmic reticulum (ER) to the nucleus. Nuclear-localized CTR1 inhibits the transcriptional activity of ETHYLENE-INSENSITIVE3 (EIN3) in a kinase independent manner, resulting in rapid reset of the ethylene response, thereby promoting fast growth recovery.

The input voltage is lower than the pulsed DC voltage, and the regulated voltage is lower than the input voltage.
