How the apple escaped cultivation in North America

Area of Science:

• Evolutionary biology
• Plant genetics
• Ecology

Background:

• Domesticated plants adapt to new environments, forming local landraces.
• Some crops become feral, evolving independently of human cultivation.
• The genetics of feral perennial crops remain largely unstudied.

Purpose of the Study:

• To investigate the genetic evolution of feral perennial crops.
• To understand the adaptability of domesticated apple (Malus domestica) in North America.

Main Methods:

• Genetic analysis of feral apple populations.
• Comparison with cultivated apple varieties and native species.

Main Results:

• Domesticated apples exhibit a remarkable ability to thrive and reproduce in North America.
• Feral apples can establish and persist without genetic introgression from local species.
• This demonstrates the evolutionary plasticity of domesticated perennial crops.

Conclusions:

• The study provides new insights into the genetics of feral perennial crops.
• Domesticated apples showcase significant adaptive potential in novel ecosystems.
• Understanding feral crop evolution is crucial for predicting plant invasions and managing biodiversity.
