Citizen science AI revealed earlier flowering in grasses at higher latitudes. Common garden experiments showed the opposite, reconciling this discrepancy by integrating genetic and environmental factors for adaptation insights.
Area of Science:
- Ecology
- Evolutionary Biology
- Plant Science
Background:
- Species adapt to diverse habitats using phenological regulation mechanisms.
- Latitudinal trends in plant phenology are crucial for understanding adaptation.
Purpose of the Study:
- Investigate latitudinal flowering time trends in warm-season perennial grasses using AI and field experiments.
- Uncover the genetic and environmental mechanisms driving phenological adaptation in plants.
Main Methods:
- Utilized computer vision AI to analyze citizen science observations across North America.
- Conducted common garden experiments with switchgrass (Panicum virgatum) to assess flowering time plasticity.
- Integrated genetic data (GI-Hd1-FTL1 haplotypes) with environmental profiles and plasticity.
Main Results:
- Observed an earlier flowering trend at higher latitudes in wild grass populations via AI analysis.
- Common garden experiments revealed an opposite latitudinal trend for switchgrass.
- Differential plasticity of flowering time gene haplotypes reconciled the observed discrepancies.
Conclusions:
- Citizen science and designed experiments are complementary tools for studying adaptation.
- Genetic plasticity and environmental interactions are key drivers of plant phenological adaptation.
- Understanding these mechanisms is vital for predicting future adaptive shifts in plant populations.
