How plants survive in colder regions?

An international research team led by Osaka Metropolitan University has uncovered vital insights into how the repair of photosynthetic protein complexes can enhance plant survival in colder climates. They cultivated Arabidopsis thaliana, also known as thale cress, from various ecotypes around the globe. Initially, all plants were grown at a comfortable 22°C. Thereafter, some were held as a control group, while others faced a chill at 12°C for three days.
