Greater Resistance to Drought‐Induced Embolism Is Linked to Higher Yield Maintenance in Soybean

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT With increasing drought events worldwide, crop breeding must focus on drought resistance to maintain crop yields. To ensure a high level of gas exchange and growth, plants need to maintain the integrity of their vascular system under drought conditions. While the impact of drought‐induced vascular damage on tree species is well‐documented, its

Expert opinions regarding the concept of blue carbon in seaweed systems

open access: yesPhycological Research, EarlyView.
SUMMARY A collection of expert opinions critically evaluates the role of seaweed in blue carbon strategies for climate change mitigation. While the concept of fast‐growing seaweed to capture atmospheric carbon is appealing, the experts largely agree that its potential for direct, long‐term carbon sequestration is currently overstated and faces ...
