Your tomato plants already know how to survive a late frost, they just can't shout loud enough. Scientists found two tiny chemical signals that tomato pollen sends out when temperatures drop during bloom, a kind of molecular alarm that keeps pollen alive long enough to set fruit. Plants engineered to broadcast that alarm more strongly held onto half the harvest that cold snaps would have destroyed. The same trick worked in rice, suggesting the rescue signal is ancient and widespread.

That theme of plants carrying defenses they haven't fully turned on echoes across this week's research. Disabling a single gene let tomato plants blast their built-in insect repellents at full volume against a devastating moth, with zero growth penalty. Bacteria pulled from sago palm roots helped tomatoes thrive in salty soil. Underground fungi thought to be helpless without a host turned out to run their own supply networks for over a year when given the right food.

The toolkit is already in the soil and the stem. We're just learning which switches to flip.
