![]() This review provides a strategy for securing crop-based nutrition against severe pathogen attacks in the era of climate change.Ĭlimate change is a major factor in determining where humans can live on the planet under tolerable and safe conditions ( Timmermann et al., 2022). Here, we summarize and discuss the effects of major environmental factors such as temperature, humidity, and carbon dioxide concentration on plant immunity systems. Therefore, understanding the effects of climate change on plant innate immunity and identification of elite genes conferring disease resistance are crucial for the engineering of new crop cultivars and plant improvement strategies. Development of new plant breeding technologies including site-directed nucleases offers the opportunity to mitigate the effects of the changing climate. Since climate change has accelerated recently and is expected to worsen in the future, we have reached an inflection point where comprehensive preparations to cope with the upcoming crisis can no longer be delayed. ![]() ![]() In particular, the emergence of new infectious plant pathogens and the geographical expansion of plant disease incidence result in serious yield losses of major crops annually. Rapid climate change caused by human activity is threatening global crop production and food security worldwide. ![]()
