Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If lateral shoot angles are increased to improve plant architecture and yield per unit area, then productivity is improved, but the complexity of genetic regulation mechanisms increases
Solution Approach 1:
The patent extracts and isolates the specific LBA5 gene from the complex genetic regulation network controlling lateral shoot angles. By identifying and utilizing this single key gene, the invention simplifies the genetic regulation mechanism while maintaining the ability to control plant architecture and improve productivity through targeted genetic modification.
Solution Approach 2:
The patent employs parameter changes by modifying the expression level of the LBA5 gene to control lateral shoot angles. Through overexpression or suppression of this single gene, the invention achieves continuous variation in plant architecture traits, enabling optimization of yield per unit area without requiring complex multi-gene regulation systems.
2Manufacturing precision
If molecular genetic research is conducted to identify genes controlling lateral shoot angles, then manufacturing precision is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent replaces traditional mechanical and phenotypic observation methods with molecular biological techniques for detecting and measuring genes controlling lateral shoot angles. By using molecular markers, gene sequencing, and expression analysis, the invention achieves precise identification of the LBA5 gene and its functional variants, significantly improving manufacturing precision while providing systematic methods for gene detection.

AI summary
A gene LBA5 for regulating lateral shoot angles, growth habits, and a plant architecture of Arachis hypogaea L., and use thereof are provided. In the present disclosure, a major gene LBA5 for controlling lateral shoot angles, growth habits, and a plant architecture of Arachis hypogaea L. is mapped and cloned from Arachis hypogaea L., which includes two homologous genes LBA5b and LBA5a and promoters thereof. The allelic variations of the gene can be selected through crossbreeding and backcrossing to achieve the genetic improvement on an angle between an Arachis hypogaea L. lateral shoot and a main stem. Through a genetic engineering operation for the gene and a change for a promoter sequence of the gene, the function or expression level of this gene in a procumbent Arachis hypogaea L. variety can be adjusted to further regulate an angle between an Arachis hypogaea L. lateral shoot and a main stem.
