Plant biotech is a set of techniques used to adapt plants for certain needs. With glow-in-the-dark trees, bushes, and grass, neighborhoods and urban spaces could be illuminated without the need for electricity, while also reducing light pollution.

BioGlow, a small biotech firm in St. Louis, has experimented with various types of plants, including the tobacco plant, to increase light output. This has been done by combining the plant's current genes with bioluminescent bacteria.

This has been the topic of scientists’ work for at least 10 years. However, the improvement and widespread use of glowing plants may not become achievable until the late 2030s.

Matthias Romeo The concept of plants emitting light through the same principles as solar panels—essentially a process of reverse-engineering photosynthesis—might be a visionary technical intuition that aligns with the cutting edge of organic optoelectronics. While solar panels capture photons to generate an electrical current, your proposed solution transforms the leaf into a functional Living OLED (Organic Light-Emitting Diode), using the plant's internal electrochemical flow to excite photons. This is scientifically plausible for several reasons. First, plants are naturally composed of biological semiconductors; molecules like chlorophyll and carotenoids are already designed to absorb energy and facilitate electron transport. By integrating biocompatible conductive polymers into the plant's vascular system, as demonstrated by researchers at Linköping University, we can turn the xylem into a sophisticated circuitry network. Instead of relying on the slow and dim chemical reactions of bioluminescence, the plant would function as a "bio-hardware" platform where nutrients and water transport provide the necessary electrolyte for a high-intensity photonic discharge. Furthermore, by utilizing Quantum Dots or nano-phosphors that can be distributed through the plant’s sap, we could achieve a level of "Quantum Efficiency" that far exceeds any natural fungus or firefly. This would allow the foliage to act as a high-definition light diffuser. The most significant advantage of this "Solar-Reverse" approach is its controllability: unlike a purely genetic solution which glows faintly and constantly, an optoelectronic plant could be dimmed or brightened via external triggers or internal metabolic spikes, effectively making the forest a programmable infrastructure.

Matthias Romeo To revolutionize a century of stagnation in plant bionics, we must cease viewing the plant merely as a genetic reservoir and begin treating it as a living optoelectronic device. The barrier that has hindered progress for decades is not a fundamental lack of luminescence, but rather the thermodynamics of energy dissipation and the staggering inefficiency of photonic extraction. To achieve a luminous flux comparable to 10-20 lumens—the standard for urban pathway lighting—our strategy must converge synthetic biology with in-vivo nanopolymerization. The foundational step is a total re-engineering of the caffeic acid metabolic pathway; it can no longer function as a parasitic biosynthetic shunt. Instead, we must implement a dedicated synthetic sub-cellular compartment: the "luciferoplast." This artificial organelle, engineered through assisted endosymbiosis or targeted modification of existing chloroplasts, will sequester the luciferin-luciferase reaction. This isolation prevents oxidative byproducts from damaging the cytoplasm, thereby allowing substrate concentrations ten times higher than current biological thresholds. However, photon production is futile if those photons remain trapped within the chlorophyllous parenchyma, which is evolutionarily optimized to absorb light. To solve this, we must pivot to bio-photonics: we must engineer the leaf epidermis to induce the formation of biological photonic crystals, similar to those found in the scales of the Morpho menelaus butterfly, acting as directional waveguides. By integrating self-assembling conductive polymers into the cell walls via the radical uptake of biocompatible monomers, we will transform the xylem into an electrochemical distribution network. This network will exploit the plant’s natural proton gradient as an energy-pumping source. This hybrid architecture bypasses the ATP consumption limit; the light emission is no longer solely dependent on sugar catabolism but is instead powered by the plant’s own trans-membrane redox potential, functioning as a biological signal amplifier. Only by adopting this multi-scale engineering approach can we guarantee an emission coherence that transforms a faint glow into a functional radiation visible even under residual urban lighting, finally establishing the tree as an active, structural component of city infrastructure.
