GENETIC TOOLS USEFUL FOR IMPROVING A PLANT'S STRESS TOLERANCE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17768256 titled 'GENETIC TOOLS USEFUL FOR IMPROVING A PLANT'S STRESS TOLERANCE
Simplified Explanation
The present disclosure relates to methods and composition matters for improving a plant's stress tolerance and speedy recovery to growth from stress by expressing a constitutive triple response 1 (CTR1) protein kinase in the nucleus of the plant cell.
- Plants need to acclimate to stress quickly to survive environmental extremes and recover once stress is removed.
- Ethylene-induced growth cessation triggers the translocation of CTR1 protein kinase from the endoplasmic reticulum to the nucleus.
- Nuclear-localized CTR1 inhibits the transcriptional activity of ETHYLENE-INSENSITIVE3 (EIN3) in a kinase-independent manner, promoting fast growth recovery.
Potential Applications
This technology could be applied in agriculture to improve crop yield and quality by enhancing plants' ability to recover from stress quickly.
Problems Solved
1. Slow growth recovery following stress in plants. 2. Limited stress tolerance in plants.
Benefits
1. Increased plant stress tolerance. 2. Faster growth recovery post-stress. 3. Enhanced crop productivity.
Potential Commercial Applications
Improving stress tolerance in crops for increased agricultural productivity.
Possible Prior Art
There may be prior research on the role of CTR1 protein kinase in plant stress responses, but this specific method of nuclear localization and its impact on growth recovery may be novel.
Unanswered Questions
How does the constitutive expression of CTR1 protein kinase affect other signaling pathways in plants?
Further research is needed to understand the potential crosstalk between the CTR1 protein kinase pathway and other signaling pathways in plants.
What are the long-term effects of constitutive expression of CTR1 protein kinase on plant growth and development?
Long-term studies are required to assess any potential unintended consequences or alterations in plant physiology due to the constitutive expression of CTR1 protein kinase.
Original Abstract Submitted
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.
