Implementation

PetalGlow is designed to increase bioluminescence by modifying the plant's natural metabolic pathways and introducing new genetic elements. The engineering effort focuses on optimizing the caffeic acid cycle and incorporating genes from fungal bioluminescence systems.

1. Target Pathway Caffeic Acid Cycle:

The caffeic acid cycle is integral to PetalGlow's bioluminescence. This cycle involves the conversion of substrate supply like phenylalanine and tyrosine into caffeic acid, a crucial intermediate in the synthesis of bioluminescent compounds. By enhancing this pathway, the plant can produce more of the substrates required for bioluminescence.

2. Introduction of Bioluminescent Genes:

PetalGlow's bioluminescence is achieved by introducing genes that enable the synthesis and recycling of fungal luciferin. These genes are primarily sourced from fungal organisms. The key components include:

• Hispidin Synthase (HispS): Catalyzes the formation of hispidin, which is a precursor to fungal luciferin.
• Hispidin-3-Hydroxylase (H3H): Hydroxylates hispidin to produce 3-hydroxyhispidin, which then forms fungal luciferin.
• Luciferase (Luz): Catalyzes the oxidation of fungal luciferin, resulting in light emission.
• Caffeyl Pyruvate Hydrolase (CPH): Catalyzes the hydrolysis of caffeyl pyruvate back into caffeic acid, allowing the cycle to continue.

3. Gene Modification and Integration:

The production process begins with constructing a synthetic pathway that combines enhanced caffeic acid synthesis with the fungal bioluminescent system. This involves:

• Overexpression of Key Enzymes: Genes like PAL (Phenylalanine Ammonia-Lyase), C4H (Cinnamate-4-Hydroxylase), and C3H (Cinnamate-4-Hydroxylase) are overexpressed to increase the production of caffeic acid.
• Integration of Fungal Bioluminescent Genes: Genes from fungi that produce luciferin and luciferase are introduced into the plant genome, allowing the plant to sustain the bioluminescent reaction.

4. Engineering the Bioluminescent Pathway:

The genetic elements required for bioluminescence are assembled into a plasmid vector. This plasmid includes:

• Promoters and Regulatory Sequences: A strong promoter, such as the CaMV 35S promoter, ensures high expression levels of the introduced genes throughout the plant tissues.
• Gene Stacking: The genes necessary for both caffeic acid production and bioluminescence are organized sequentially within the plasmid, ensuring their coordinated expression in the plant cells.

1. Vector Construction:

• Plasmid Vector: A plasmid vector with a multiple cloning site (MCS) is selected to incorporate the genes responsible for caffeic acid synthesis and bioluminescence. It features a strong promoter for gene expression, a selectable marker for antibiotic resistance, and the necessary bioluminescent gene sequences.
• Restriction Enzymes and Ligation: The plasmid and target genes are cut with restriction enzymes and then ligated together using DNA ligase, creating the recombinant plasmid.

2. Transformation:

• Agrobacterium-Mediated Transformation: The recombinant plasmid is introduced into Agrobacterium tumefaciens using electroporation. This bacterium then transfers the genetic material into plant cells via T-DNA integration.
• Plant Transformation: The Agrobacterium infects plant tissues, typically leaf discs, initiating the genetic transformation process.

3. Selection and Regeneration:

• Antibiotic Selection: Transformed cells are cultured on antibiotic-containing media to select for those that successfully integrated the plasmid.
• Regeneration: The selected cells are regenerated into whole plants in a tissue culture environment, using plant hormones to induce root and shoot development.

1. Cultivation Process

The cultivation of PetalGlow plants will take place in highly controlled environments to ensure consistent and reliable expression of the bioluminescent trait. This process will involve regulating key factors such as light, temperature, humidity, and nutrient supply to create optimal growth conditions. Additionally, genetic stability will be closely monitored throughout cultivation to maintain uniform bioluminescence across all plants, ensuring that each PetalGlow plant exhibits the desired glowing effect at its full potential.

2. Tissue Culture:

• Initial Growth: Transformed plants are initially grown in sterile in vitro conditions with carefully balanced nutrients and hormones.
• Acclimatization: Once roots and shoots develop, plants are gradually acclimatized to external conditions by controlling humidity and light exposure.

3. Optimal Growth Conditions:

• Light: Requires 12-16 hours of direct sunlight or equivalent artificial light.
• Temperature: Optimal growth occurs between 23°C to 26°C. Protect from temperatures below 10°C and above 35°C.
• Soil and Watering: Use well-draining, organic-rich soil with a pH of 5.5 to 6.5. Water moderately to maintain humidity and prevent root rot.

• Luminescence Quantification: In the future, light intensity will be measured with a luminometer to ensure the consistency and inensity of each Petalglow plant.
• Environmental Interaction: Testing plants will be tested under varying conditions to ensure consistent bioluminescence without degradation over time.
