Bt agave: why it is time to explore a new biotechnological frontier.

Climate Adaptation
Agave planted in xeric gardens and dryland restoration sites faces the same insect pest pressure that slashes commercial yields — and a bacterial pest-resistance technology already protecting corn and cotton may soon be deployable in these drought-proof giants.
Agave plants are remarkably tough — they thrive in hot, dry places where almost nothing else grows — which makes them increasingly important as the world gets drier. The problem is that insects damage agave crops badly enough to hurt farmers' livelihoods. Scientists are now making the case that a well-tested pest-fighting tool borrowed from agriculture — a natural protein from soil bacteria already built into corn and cotton — could be introduced into agave plants to help them fight off these insects on their own.
Key Findings
Drylands cover 41% of Earth's surface and are expanding due to climate change, raising the strategic importance of drought-tolerant crops like agave.
Agave's extremely low water requirements and high biomass productivity make it one of the most sustainable crops for semi-arid regions, yet insect pests significantly reduce yields and economic returns.
Recent advances in plant transformation and regeneration techniques have lowered the historical barriers to genetic engineering in monocots, making Bt integration into agave technically feasible for the first time.
chevron_right Technical Summary
Agave is one of the most water-efficient crops on Earth, thriving in dryland conditions where most plants fail — but insect pests are a serious threat to yields. Researchers argue that inserting Bt pest-resistance genes (already proven in corn and cotton) into agave is now technically within reach and could make this climate-resilient crop even more viable.

Agave is a genus of monocots native to the arid regions of the Americas. The genus is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves.
