Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to effectively control plant flowering time by sensing small changes in ambient temperature, as the molecular mechanisms for temperature-induced flowering time regulation remain incomplete.
Innovation Solution
Regulating the formation of the SVP-FLM-β protein complex in plants to control flowering time by inhibiting or promoting its formation using RNAi techniques, such as SVP RNAi and FLM-β RNAi, which influence the expression of flowering promoter genes like FT, SOC1, and TSF.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional flowering time control methods are used, then flowering time can be controlled under extreme temperatures (4°C or below, 37°C or above), but the mechanism cannot sense small changes in ambient temperature (10°C to 27°C)
Solution Approach 1:
The patent changes the operational parameters of the flowering control system by introducing the SVP-FLM-β protein complex, which operates at ambient temperatures (10°C to 27°C) rather than extreme temperatures. This allows the system to detect and respond to small temperature variations (1°C to 5°C changes) that conventional mechanisms cannot sense, thereby improving temperature sensing precision while maintaining adaptability across a wide temperature range
Solution Approach 2:
The SVP-FLM-β protein complex acts as an intermediary mechanism between temperature sensing and flowering time control. This complex specifically responds to small temperature changes by regulating the expression of flowering promoter genes (FT, SOC1, TSF), serving as a mediator that translates subtle thermal signals into developmental responses, thus resolving the contradiction between precise temperature sensing and broad adaptability
2Manufacturing precision
If the SVP-FLM-β protein complex formation is regulated to control flowering time, then temperature sensitivity is reduced and flowering time is precisely controlled, but the complexity of the molecular mechanism increases
Solution Approach 1:
The patent segments the flowering time control mechanism into distinct functional components: the SVP-FLM-β protein complex as the temperature-sensing module, and the flowering promoter genes (FT, SOC1, TSF) as the execution module. This segmentation allows precise control of flowering time through regulated protein complex formation while organizing the molecular mechanism into manageable, functionally distinct units that can be independently studied and manipulated
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for precise control of flowering time by reducing temperature sensitivity and promoting or delaying flowering based on ambient temperature, thereby addressing the challenge of sudden temperature changes affecting plant development.
Implementation Method 1
the SVP-FLM-β protein complex is a regulating factor for plant flowering that senses small changes in ambient temperature
Implementation Method 2
RNA interference (RNAi) is a mechanism capable of inhibiting the expression of a gene in a highly specific and efficient manner, in which degradation of the mRNA of a target gene is inhibited by introducing a double-stranded RNA

AI summary
The present invention relates to a method of controlling the flowering time of a plant by regulating the formation of the SVP-FLM-β protein complex, based on the finding that the SVP-FLM-β protein complex is a regulating factor for plant flowering that senses small changes in ambient temperature. The FLM-β RNAi and SVP RNAi for controlling flowering time according to the present invention can be used to control flowering time by inhibiting the expression of FLM-β and SVP or regulating the interaction therebetween, and thus, they can prevent a decrease in crop production or a change in the ecosystem from being caused by a sudden change in temperature.
