1Quantity of substance
If traditional breeding methods are used to increase plant biomass, then biomass levels can be improved over time, but the process is time-consuming and slow
Solution Approach 1:
The patent replaces traditional mechanical breeding methods with molecular genetic approaches. Specifically, it uses PCR-based marker systems and DNA sequencing to identify and manipulate genes controlling biomass, substituting the slow mechanical process of selective breeding with accelerated molecular selection and transformation techniques.
Solution Approach 2:
The patent changes the parameter of selection precision by moving from phenotypic selection to genotypic selection using molecular markers. By identifying specific DNA sequences associated with biomass traits, the method enables direct selection of desired genetic parameters, dramatically reducing the time required to achieve biomass improvement.
2Productivity
If molecular genetic approaches are used to rapidly produce plants with increased biomass, then biomass production can be enhanced quickly, but the complexity of the methodology increases
Solution Approach 1:
The patent segments the complex task of biomass improvement into distinct molecular steps: (1) developing PCR markers for biomass-associated genes, (2) screening plants using these markers, (3) selecting individuals with desired genotypes, and (4) propagating selected plants. This segmentation makes the complex molecular process more manageable and systematic.
Solution Approach 2:
The patent introduces molecular markers as intermediaries between the target biomass trait and the selection process. These DNA markers serve as detectable proxies for the actual biomass phenotype, allowing indirect but rapid selection without requiring complex phenotypic measurements or lengthy growth trials.
3Manufacturing precision
If specific genes and sequences are identified to enhance biomass, then precision of biomass enhancement improves, but the difficulty of detecting and measuring these genetic elements increases
Solution Approach 1:
The patent creates simplified copies of complex genetic information through PCR amplification of specific DNA regions. By copying and amplifying marker sequences associated with biomass traits, the method makes these previously undetectable genetic elements easily measurable and selectable using standard molecular biology techniques.
