Title:How to respond to elevated CO2 on Se in Chinese selenium hyperaccumulator?

Selenium (Se) is an essential trace element to maintain human health, especially for anti-inflammatory, antioxidant, and immune effects. Till now, it is worldwide for Se deficiency in soils (40%) and populations (14%). However, there is little information on Se changes in crops under global warming conditions although significant decreases in staple crops and vegetables were verified in Zn, Fe and vitamins levels because of elevated CO2. Here, a Chinese Se hyperaccumulating plant, Cardamine hupingshanensis, was employed to study the Se level changes and their relationship with the rhizosphere microbiome under an elevated CO2 scenario. So how to survive for Chinese Se plant under global warming? Is it beneficial to Se accumulation or not? What is the significance to future hidden hunger?
