Arctic Plants Under Environmental Stress: A Review

Arctic plants inhabit extremely cold environments and are exposed to a range of abiotic stress factors. Arctic species exhibit remarkable adaptability to multiple environmental challenges, including a short growing season, low summer temperatures, continuous 24-h daylight during the polar day, limited nitrogen availability in soils, water scarcity, and strong winds. This review examines the key features of growth, development, and reproduction in Arctic plants, as well as their physiological and genomic adaptations to extreme climatic conditions. While Arctic plants show remarkable physiological tolerance, community-level resistance varies regionally and remains an open question.
