Coping with adverse environmental conditions is central to plant survival in nature so understanding the photoprotective mechanisms of light acclimation is important for crop improvement. Therefore, effective acclimatory mechanisms at whole plant, cellular and molecular levels are essential to accommodate short and long-term exposure to potentially photodamaging full sunlight and environmental stresses, such as drought and temperature extremes that lead to plant death or greatly reduced crop yields due to free radical damage. This project brings together a unique cross-disciplinary expertise in biophysics, biochemistry, physiology and genomics to elucidate the known mechanisms and identify unknown factors in photoprotection.

在自然界中，应对不利的环境条件是植物生存的核心，因此了解光适应的光保护机制对作物改良具有重要意义。因此，在整个植物、细胞和分子水平上，有效的适应机制对于适应短期和长期暴露于潜在光损伤的充足阳光和环境胁迫（如干旱和极端温度）是必不可少的，这些胁迫会导致植物死亡或因自由基损伤而大大降低作物产量。该项目汇集了生物物理学、生物化学、生理学和基因组学方面独特的跨学科专业知识，以阐明光保护的已知机制并确定未知因素。
