Arabidopsis thaliana

Arabidopsis thaliana

Each individual in a population carries a degree of genetic variation.  Individuals often carry rare alleles that are not harmful but also offer no immediate advantage for the individual carrier, but if passed on could become advantageous in future environmental conditions.  

Loss of this genetic variability or loss of evolutionary flexibility, could limit a population to respond to long term changes in the environment.  

Arabidopsis thalianaEdit

Researchers are studying the european plant Arabidopsis thaliana to find clues about how this plant is adapting to climate change.  They have found genes that have been passed on to Arabidopsis that optomizes the plant's survival and reproduction in changing weather conditions.  Identifying the specific favorable alleles that this plant possesses may enable researchers to learn more about the ability for other plants to adapt to climate change as well.
