e1“We studied the interaction of a CO 2 doubling and two levels of nitrogen fertilizer on the growth and chemical composition of tall fescue ( Festuca arundinacea Schreber cv. KY‐31) when infected and uninfected with the mutualistic fungal endophyte Neotyphodium coenophialum Morgan‐Jones and Gams.”
e2“plants grown in twice ambient CO 2 concentrations: photosynthesized 15% more”
e3“Plants infected with the endophytic fungus: photosynthesized 16% faster in high N compared with under low N”
