Interactive effects of elevated CO concentration and combined heat and drought stress on tomato photosynthesis.

Background: Extreme weather events are predicted to increase, such as combined heat and drought. The CO concentration ([CO]) is predicted to approximately double by 2100. We aim to explore how tomato physiology, especially photosynthesis, is affected by combined heat and drought under elevated [CO] (e [CO]).

Combined high light and heat stress induced complex response in tomato with better leaf cooling after heat priming.

Light and temperature are two primary environmental factors for plant growth and development. The response of plants to multiple stresses of high light intensity and heat stress are complex. The priming effects of high light and heat stress on improving heat tolerance of plants need to be further illuminated.
