Tomato
Those neighbors, never touched by aphids, preemptively activate anti-aphid defenses.
Tomatoes communicate underground. When aphids attack a tomato plant, it doesn't just defend itself - it releases chemical signals into its roots that propagate through mycorrhizal fungal networks to neighboring plants. Those neighbors, never touched by aphids, preemptively activate anti-aphid defenses. This is biological early warning: one plant's crisis becomes the community's preparation.
But tomatoes also demonstrate how organisms navigate environmental thresholds. They germinate optimally at 20-30°C, rarely below 10°C, and face heat damage above 35°C. These aren't absolute barriers - they're probability ranges shaped by evolutionary history. A tomato seed at 9°C isn't definitively dead; it's in a state of conditional viability where germination becomes increasingly unlikely. This probabilistic approach to environmental sensing reflects biological reality: thresholds are gradients, not walls.
For business, tomatoes illustrate two principles: information networks enable collective defense (one company's threat intelligence can immunize partners), and strategic thresholds are probabilistic, not binary. Companies that treat market conditions as simple go/no-go decisions miss the gradient of conditional viability. Success often requires operating in zones where outcomes are probable but not certain - just like tomato seeds germinating at suboptimal temperatures.
Notable Traits of Tomato
- Forms arbuscular mycorrhizal networks
- Transmits aphid attack warnings through fungal networks
- Receiving plants preemptively activate defenses
