Transcriptional Repressors of Cytokinin Signaling and Their Use

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes engineered fusion proteins that function as transcriptional repressors to control cytokinin signaling in plants. By introducing genes encoding these proteins into plants, it is possible to create transgenic plants with improved traits related to seed size, seed filling, seed loss, germination speed, and enhanced root systems. The invention covers the proteins, the genetic materials encoding them, vectors and cells carrying these genes, as well as the resulting transgenic plants and methods for producing them.

Use CasesContent extracted from patent full text and abstract with AI.

• Developing crop plants with larger and better-filled seeds for higher yield.
• Producing plants that have reduced seed loss, improving harvest efficiency.
• Creating seeds that germinate faster and support quicker plant reproduction cycles.
• Generating plants with more robust root systems to enhance nutrient uptake and drought resistance.
• Genetically modifying staple crops (e.g., rice, wheat, corn) for improved agricultural performance.

BenefitsContent extracted from patent full text and abstract with AI.

• Increased crop yield due to larger and better-filled seeds.
• Reduced losses during harvest because of minimized seed loss.
• Shorter germination and reproductive cycles, allowing for faster planting and harvesting.
• Enhanced root systems lead to better plant health, resilience, and productivity.
• Broad applicability across various crop species, supporting food security and sustainable agriculture.

Patent Abstract

The invention relates to fusion proteins capable of acting as transcriptional repressors of cytokinin signaling, to polynucleotides encoding these fusion proteins, to vectors and cells comprising these polynucleotides, and to transgenic plants and parts thereof comprising these polynucleotides, vectors, and cells. The invention further relates to a process for making these transgenic plants and to the use of these transgenic plants for producing seeds of enhanced size, with enhanced seed filling, with reduced seed loss and/or with more rapid germination, and/or for producing a live root system with increased root mass, root length and/or root branching. The invention also relates to a method for enhancing the seed size, for enhancing seed filling, for reducing seed loss, and/or for reducing germination time and/or reproduction time, and/or for enhancing the root mass, root length and/or root branching of a plant and to seeds obtainable by the methods of the present invention.
