All important crops need to have their responses to various diseases studied under a range of expected climate conditions
levels were driving the plants to produce jasmonic acid more readily, to keepto flourish. Chemical analysis of the plants proved this theory correct.
To make matters even more complicated, evidence is mounting that changes in temperature and water availability also shift plant immune responses. André Velásquez and Sheng Yang He, at Michigan State University, wrote an extensive review on the warfare between plants and diseases inlast year. They noted that though some valuable crops, such as potatoes and rice, experience less disease as moisture levels increase, this is not the case for most plants.
The problems are daunting, then, but there is a way to try to solve them. First, all important crops need to have their responses to various diseases studied under a range of expected climate conditions. Second, genes which grant resistance to diseases that might become severe in the future need to be tracked down. Modern crops have been streamlined by artificial selection to be excellent at growing today.
