Transgenic Polypeptides for Saline and Oxidative Stress Tolerance in Plants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are inadequate in enhancing plant growth under saline and oxidative stress conditions, leading to stunted growth and reduced yields in agricultural and horticultural crops due to sensitivity to salt and reactive oxygen species.
Innovation Solution
Introduction of transgenic plants with modulated levels of tolerance to salinity and oxidative stress through the expression of recombinant DNA molecules encoding specific polypeptides, which enhance salt tolerance and oxidative stress tolerance, using Hidden Markov Model bit scores and sequence identities to identify effective nucleotide sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If plants are grown under saline and oxidative stress conditions, then agricultural productivity is maintained, but plant growth becomes stunted and yields are reduced due to salt sensitivity and reactive oxygen species damage
Solution Approach 1:
The patent modifies plant tolerance parameters by introducing transgenic polypeptides that alter the plant's physiological response to salinity and oxidative stress, changing the sensitivity parameters to enable growth under previously harmful conditions
Solution Approach 2:
The patent uses recombinant DNA molecules encoding specific polypeptides as intermediaries to mediate between the harmful saline/oxidative environment and the plant's cellular processes, protecting against damage while maintaining productivity
2Productivity
If current methods are used to enhance plant growth under stress conditions, then some growth enhancement may be achieved, but the methods are inadequate and stunted growth persists
Solution Approach 1:
The patent replaces conventional breeding and agronomic methods with molecular biology techniques, substituting mechanical/chemical approaches with genetic engineering to achieve precise control over stress tolerance characteristics
Solution Approach 2:
The patent uses recombinant DNA technology to copy and introduce specific gene sequences into plants, creating transgenic copies of tolerance-enhancing polypeptides that provide controlled growth enhancement under stress
3Reliability
If transgenic plants with modulated tolerance levels are introduced, then plants can grow without stunted growth and diminished yields, but this requires complex recombinant DNA molecules and sequence identification methods
Solution Approach 1:
The patent employs self-organizing molecular processes where recombinant DNA molecules automatically fold and function as intended, and Hidden Markov Models automatically identify effective sequences through statistical analysis, reducing the need for complex external intervention

AI summary
The present invention relates to isolated nucleic acid molecules and their corresponding encoded polypeptides able confer the trait of improved plant size, vegetative growth, growth rate, seedling vigor and/or biomass in plants challenged with saline and/or oxidative stress conditions. The present invention further relates to the use of these nucleic acid molecules and polypeptides in making transgenic plants, plant cells, plant materials or seeds of a plant having plant size, vegetative growth, growth rate, seedling vigor and/or biomass that are improved in saline and/or oxidative stress conditions with respect to wild-type plants grown under similar conditions.
